How Much Head Should A Beer Have?

0.5-1 inch head Generally, you should try to pour your beer to have a 0.5-1 inch head.

How much head is beer supposed to have?

How To Pour Beer > > Pouring beer is an art, and definitely part of the overall tasting experience. We always suggest that you drink a beer out of a glass, and recommend that you read, It’s a great primer to understating why, and a guide guide to pairing a beer to its appropriate glass. The following demonstrates the most common pouring technique which can be applied to most beers and glassware types. You’ll also find that most bartenders pour draught beer as follows too. Steps to a Perfect Pint

Use a clean glass. A dirty glass, containing oils, dirt or residuals from a previous beer, may inhibit head creation and flavours. Hold your glass at a 45° angle. Pour the beer, targeting the middle of the slope of the glass. Don’t be afraid to pour hard or add some air between the bottle and glass. At the half-way point bring the glass at a 90° angle and continue to pour in the middle of the glass. This will induce the perfect foam head. And remember, having a head on a beer is a good thing. It releases the beer’s aromatics and adds to the overall presentation. You may also want to gradually add distance between the bottle and glass as you pour, to also inspire a good head. An ideal head should be 1″ to 1-1/2″.

With bottled conditioned beers, that may have a considerable amount of yeast in the bottle, you may wish to watch closely as you pour, if you don’t like yeast in your poured beer. However, this is the highlight of some beers and actually wanted. Just note that the inclusion of yeast will alter the clearness and taste of your poured beer, and lively yeast is high in vitamins and nutrients! > > : How To Pour Beer

Should beer have a large head?

Different types of beer have different amounts of head – OK, so if beer foam is naturally occurring, why do different beers have different amounts of head? Well, it comes down to the brewing process, beer cultures and personal preference. For example, if you’re enjoying a pint in Germany, you’re likely to find it comes with a thick layer of foam – up to 2 inches (or 5cm) in fact and in Belgium a head of thick foam signifies the best beer.

• Pilsners / Lagers: a thick 2-3cm (approx.1 inch) head is normal and preferred
• IPAs / Pale Ale: should easily produce at least 1 inch of beer foam
• Bitters / Stouts / Porter : low carbonation so doesn’t tend to have a significant head – usually around 0.5 inch or 1cm, but some beer foam should ideally remain throughout drinking

Fun Fact: In the Czech Republic don’t be surprised if you’re served a glass almost entirely full of foam when you order a local beer, it’s even got its own name – mlíko!

Should your beer have a head?

Why You Want a Head on Your Beer – A nice head on your beer will make it less carbonated overall. You want this because that means there is less carbon dioxide going into your stomach. When carbonated beverages like sparkling ciders or soda reach your stomach acid, all the carbon dioxide gets released, which causes bloating.

How much foam head should a beer have?

In general, a beer should have a foam head of about ½ inch to a full inch thick that lasts for much of the duration of the life of the beer in the glass. Beer, in fact, is the only beverage that retains its head, and beer drinkers have come to expect this, even if only intuitively.

How long should head last on a beer?

Bubbles In Your Draft Beer Tell All The next time you’re served a cold draft beer, and before taking the first sip, study the glass and observe the bubbles. The bubbles in a glass of beer will reveal many interesting things. Bubbles show attributes of the beer style being poured. The cleanliness of the glass will provide a good indication of the condition of the beer dispensing system.

1. The process starts when the tap is opened and a glass is filled with beer.
2. The sudden change in pressure from the dispensing system to the glass causes dissolved carbon dioxide to escape from the beer as the glass fills.
3. Ideally the result is a (½ inch to 1 inch) thick head of well knitted bubbles, otherwise known as foam.

Foam is essential to delivering the true flavor and bouquet of the brew. Each type and style of beer has its own taste and aroma characteristics. Foam accentuates the aroma and enables beer to taste as the brewer intended. The gas within the bubbles also insulates, thus keeping the beer in the glass colder longer.

The head on the beer should remain until the last drink is taken. Foam (bubbles) should cling to the glass sides with each drink; this is called lacing, and is an indication the beer glass has been cleaned properly. A creamy head on a beer suggest the beer dispensing system is in balance, and that the carbonation brewed into the beer is being maintained to the brewer’s specification.

A head of foam on the top of a beer is ideal; however, bubbles forming on the sides or bottom of the beer glass and then rising to the top may indicate the glass is not “beer clean.” Bubbles form at the sides and bottom of a glass, where residue or microscopic cracks serve as starting points for carbon dioxide molecules to gather. An exception to this is laser etched glassware. Brewers are now marketing glasses where a logo or insignia is laser engraved into the bottom of the glass. This forces bubbles to form around the etching, highlighting the brewery logo. Eventually the bubbles grow large enough to rise to the top of the glass helping to maintain the head of foam.

1. This is done to enhance the beer drinking experience and to differentiate the beer brand.
2. Another interesting characteristic of beer bubbles was studied by a chemist, Richard Zare, the Marguerite Blake Wilbur Professor in Natural Science, who published a seminal paper on the “fizzics” of beer.
3. Zare’s beer science pointed out that beer bubbles got larger and rose faster as they floated to the top of a glass.

The reason bubbles expand and accelerate as they rise is bubbles themselves act as collection sites. Each attracts more escaping CO2 or, as Zare puts it, “bubbles collect on bubbles.” The absence of bubbles usually indicates a dispensing system problem.

• The beer on tap may have lost carbonation and will taste flat.
• This is a result of the dispensing system not being set up properly or dispensing with the wrong gas.
• Beer bubbles provide many insights into the beer style and quality, glassware cleanliness and dispensing system condition.
• When served the next pint, inspect, and insist on properly performing bubbles in your beer.

What causes too much head in beer?

Foamy Beer Due to Temperature – What causes beer to foam ? In general, beer will foam when it’s served too cold. It will also foam if, and usually the more common issue is it’s too warm. Have you heard this saying before ? Beer keeps foaming after opening.

• If your keg is stored in an area with a constant temperature, then you need to make sure the temperature of the beer inside is also constant and cold.
• Maintaining consistent refrigeration (38 degrees F) is important.
• One way to check where your beer temps at is by taking a digital thermometer, pouring some beer, and temping it.

Where we want to be is 38 degrees. When beer is served warmer, it becomes unstable foams because there is too much foam in the keg. The other place to check the temperature is inside the kegerator or beer cooler. Check the temperature by placing a glass of water in there and letting it sit for 24 hrs, then use a digital thermometer to check it,

Why doesn’t my beer have a head?

Head Hunting – As a homebrewer, fine tuning carbonation will ensure a good, consitent head. Undercarbonated beer will not form a head, which, in the case of a draft pale ale, may be desirable. If the beer is very overcarbonated, it is more likely to gush, which isn’t desirable for any style of beer.

Carbonation is only one aspect of a good, frothy head. Why doesn’t carbonated water have a head? Beer is a biochemically complex beverage. Within it are compounds that promote beer foam formation and stability and others that detract. Beer foam chemistry and physics can be disturbingly complex, so keep the following in mind.

If the promoters win, you have foam. If the detractors win, you have flat beer. Within beer there are water-loving compounds (hydrophilic) and water-hating compounds (hydrophobic). Beer also has compounds called glycoproteins that are part hydrophilic and part hydrophobic.

Imagine a molecule shaped like a tadpole. The head of the molecule hates water, but the tale likes it. When many of these compounds gather together on the top of a beer, the heads group together in a circle (with the tails pointing out) creating a pocket of CO2, naturally forming bubbles. Many compounds including iso-alpha-acids from hops and certain metal ions help stabilize these structures.

However, fats and detergents tend to destabilize the bubbles and cause the foam to collapse. This is why adjuncts that are high in fat including oats and eclectic brewing spices with high oil contents such as coffee beans tend to decrease foam. Also residual soap and detergents in carboys, kegs, and bottles will hurt beer foam.

Settling out trub will decrease the amount of fatty acids in the beer. In contrast ingredients that are high in protein and glycoproteins will bolster beer froth. Some of the more common foam-positive ingredients include flaked wheat, flaked barley, wheat malt, and barley malt. Many brewers make a habit of adding a touch of wheat malt to every beer.

At low levels the impact on flavor will be small while still imparting foam-positive characteristics. Mash ingredients that are low in protein such as corn, rice, and sugar adjuncts tend to dilute foam-positive compounds in beer. Malt extracts may lose foam-positive characteristics during processing.

What does a good head of beer look like?

Welcome to Ask Kate About Beer, in which The Takeout ‘s resident beer expert answers everything you’ve ever wanted to know about beer but were too drunk to ask. Have a question? Shoot it to [email protected]. Pickle Hard Seltzer Has Us Questioning Everything Spend any time looking at beer-focused Instagram accounts, and eventually you’ll come across strange glassware; not pint glasses or tulips or glass steins, but vessels that look more like vases or fish bowls,

They’re often filled by a so-called “boss pour,” a phenomenon that’s also sometimes called an iceman pour, in which the vessel is full entirely to the brim. It’s a relatively new and—to purists—perplexing development. Even some of the very people behind Instagram accounts with boss pours admit they’re just an aesthetic thing, not to be taken too seriously.

But the rising debate over boss or iceman pours has had one silver lining: It’s spurring people to talk about what a beer’s head should look like. And if the goal is to maximize a beer’s aromas and flavors, then a head is crucial to many beer styles. Sorry, iceman.

1. The foam atop a beer head is made up of proteins and sugars in a liquid around a large quantity of gas.
2. Foam is derived from the three major non-water ingredients in beer: malted barley, hops, and yeast.
3. Crucially, trapped within that foam are compounds responsible for beer aroma and, by extension, beer flavor.

“As the foam is slightly dissipating, that’s releasing those compounds toward your nose and allowing you to get a good read on those aromatic compounds,” says Brett Bauer, lead brewer at Idle Hands Craft Ales in Malden, Massachusetts. Beer judges know that a beer’s aroma can be quick to fade, as those volatile compounds come out of suspension in liquid.

1. Foam or head helps contain some of those compounds, keeping them around longer for your enjoyment.
2. How much of a head to expect on a beer varies based on beer style.
3. A high-ABV barleywine or acidic Belgian gueuze might not have much of a head at all, while a hefeweizen or American pale ale should boast a noticeable, persistent head.

Generally, “one inch of foam tends to be the guideline for a perfect pour,” says Jess Baker, editor-in-chief of craftbeer.com, a publication of the Brewers Association trade group. If you’re pouring a beer yourself, you can maximize your chances for getting a proper head by holding the glass at a 45-degree angle and pouring the beer down the side of the glass until it’s about halfway full, then turning the glass straight up and down and pouring straight into its center.

1. A proper, mousse-like head atop a beer is considered an important mark of quality if you want to fully appreciate what’s in your glass.
2. But some consumers, perhaps with memories of college keggers still in their head, think any beer foam is a bad thing.
3. Some people looking at that head of beer and they’re like ‘Oh I’ll wait until you fill that glass up,’ like we’re trying to save a couple ounces of beer.

Maybe there’s a public perception that they’re not getting what they paid for,” Bauer says. “That’s absolutely not the case. We’re trying to present the beer in the best way possible.” Baker echoes that sentiment. She says advocating for proper beer pours and good glassware isn’t about trying to impress anyone: “This advice is not to be snobby, but truly to get the best experience the brewer of your beer intended.” I’ll drink easy-going backyard beers out of a can or bottle when the situation’s right, but if I’m trying to fully experience a beer’s flavor, I hope it’s properly poured—with a full head—into a clean glass.

Should Heineken have a head?

When drinking at a bar with friends and colleagues, how many times have you blamed the beer for tasting rough or thin, for being flat, for bloating you or even dehydrating you after a few? Consumers can be quick to dismiss the production and quality of a beer when the culprit may in fact be poor service.

1. It’s rare for mass-produced lagers to find a regular place on taps at countless bars and pubs unless it has been developed and brewed to a finely scrutinised taste and texture profile, with an unblemished record for consistency.
2. So, when ordering a beer from a big international brand, familiar throughout the world, the texture and quality of the beer should consistently be spot on.

Unless, however, the beer has been wrongly treated through transport, storage or service. When such a beer is served to a drinker the most noticeable faults will be caused by the action of pouring and presenting the beer. In particular, the failure to correctly form the beer’s head will result in a flat, unbalanced or bad tasting beer.

Heineken is tackling this problem head on with a campaign to ensure the final frontier of a beer’s journey is true to the product. Their “Five Star Pour” sessions are training bar staff at participating Heineken venues how to pour their lager perfectly. Leading the lessons is Franck Evers, who travels the world for Heineken teaching the techniques and science of pouring the prefect beer.

Australian Brews News was invited along to witness a Five Star Pour session at Platform 28 bar in Melbourne’s Docklands. Evers introduced himself to the audience of bar workers with a story about his most recognisable claim to fame. He managed the bar Gompie in Nijmegen, The Netherlands.

1. It was the bar responsible for adding the line “Alice, who the f**k is Alice?” to the Smokie hit song “Living Next Door to Alice” when played by DJs at the bar.
2. The song was an international hit when covered by a Dutch novelty band that used the bar’s name, Gompie, in 1995 (the song was originally recorded by Australian band New World in 1972).

His diverse resume also includes psychiatric nurse and tennis coach. It was his time as a bar manager at several Dutch venues that lead Evers to his current role as Heineken draughtmaster. His tagline “you buy your second beer based on the quality of the first beer” came from his observations and dealings with his customers, as he sought to understand the major annoyances of drinkers, which would directly impact on their sales.

• In Holland, the home of Heineken, Franck worked closely with his staff to establish a serving ritual that would ensure the beer would always perform as it should when consumed.
• If you improve the drinkability of the beer, you improve your income through greater turnover of the product,” he believes.

Franck’s ritual has now become the Heineken Five Star Pour. The annoyances addressed by this ritual are universal – dirty or wrong glassware, lack of or broken head on the beer, incorrect temperature and poor service. Firstly, in a noisy bar communication is 93% non-verbal, thus presentation is vital to the sensory experience of the customer. With that in mind, the Five Star Pour asks bar staff to:

Serve the beer in a clean and correctly branded glass. Open the quickly tap and allow for a single, smooth pour. Close the tap in a quick motion and allow a Dutch Style Head of foam to form naturally through the rise of CO2 from the beer, which will retain throughout consumption and prevent the beer from becoming oxidised and flat. Skim the head with a wet skimmer on a angle of 450, removing any dry or broken foam and harsh bitterness. It also seals the head with a fine layer of water, retaining the head for longer. Present the beer on a branded coaster, with the glassware logo facing the customer, with a smile and say “Enjoy your Heineken”.

“A good pour will always taste better, no matter how many you’ve had,” Evers instructed. He offered “semi-scientific proof” by allowing each of the session participants to taste both a correctly poured Heineken and a badly poured Heineken side by side.

• The results of the taste test were clear.
• The badly poured beer, with a broken head, felt thin and unbalanced in the mouth.
• The “perfect pour” was clean, crisp and much easier to drink.
• Franck Evers conducted his presentation with confidence and interest.
• He showed a genuine concern for sharing the perfect pour gospel, despite repeating this presentation countless times before.

This has been his full time job since 2005. As a representative of Heineken, it was refreshing to hear Evers speak of beer as a whole, rather than just the heritage of the brand and product or the promotional qualities of this locally-brewed-under-licence lager.

1. He taught the fundamental science of how beer’s components react to the human body, in terms of both enjoyment in refreshment and the downside through beer’s diuretic and hangover effects.
2. He explained how a well-formed and retained head can mitigate these as it prevents oxygen from reacting with the hop rho iso-alpha acids, inhibiting antidiuretic hormone and altering anti-inflammatory properties.

His presentation and lessons apply truly to almost any draught beer poured at a bar. The Heineken branding is essential to his role, but Evers did not convey an evangelical preaching for the Heineken lager product. Rather, his mission is simple: “Treat beer better and people will buy more.” Evers spoke to Australian Brews News about how these sessions were more than just a flash in the pan for the bar staff he meets.

“I make the unconscious conscious,” Franck noted as he explained that bar staff already know how to pour a beer, they just don’t know why each part of the process is important and how it impacts the beer. “They leave here and say ‘now I know why I use a skimmer’.” “My goal is that bar staff give the consumer a better experience.

Having a ritual will activate the insights that were already there. They need to know their product like a barista or cocktail waiter knows their through each stage of service.” “Think big, act little,” said Evers of Heineken’s Five Star Pour campaign, which is further supported by a 12 month program of secret shopper rewards.

• Staff at bars participating in the program will be rewarded if they serve a secret shopper using the correct Five Star Pour.
• We will visit all the bars in the program, order and drink beers, engage, explain and do some on the job training.” The underlying message of the promotion is care for the product.

If you serve the beer well, you will sell more. The brewery can control the production and distribution of the product but once the kegs arrive at the venues, the beer is in the hands of the bar staff. This is a universal message that bars should heed, whether they serve Heineken or not.

That is where the connection with the consumer happens and that is when the judgement of the product occurs. These days most major brewing companies seem to focus their extensive marking resources on new or re-worked slogans, taglines, television commercials and other imagery that has little relevance to the beer itself or its consumption.

Heineken International, which includes their joint partnership with Lion Nathan in Australia, had marketing and selling expenses €2.1 billion in 2010. They claim that there is a 20% growth rate for Heineken products under the Five Star Pour program, which is essentially a grassroots internal operation rather than consumer marketing.

1. Heineken’s focus is still firmly on sales, but this campaign it truly about the beer.
2. The Five Star Pour promotion does not advocate for any dubious flavour, performance enhancing or historical qualities of the lager product.
3. Instead, it aims to help you taste and consume Heineken the way it is designed to be, emphasising lasting freshness.

Next time you are in a bar and decide to order a Heineken, watch for a perfect pour. Maybe you will discover the quality that sends you back for a second. View a brief version of Franck’s presentation:

How much head should a Guinness have?

But Why Is the “Perfect Guinness Pour” Still a Thing? – The 2 part pour was initially used as a means of dealing with a problem that was solved by Nitrogen. In that case, what is the reasoning behind the 2 part pour today? According to a quote from Colm O’Connor, a Guinness beer specialist, the reason is “.because if we poured it in one fell swoop, the head would be too big.” Per Fergal Murray, Guinness master brewer and global ambassador, the head size on your Guinness should be between 18-20mm, which is somewhere between 11/16″-12.5/16″.

Why do German beers have so much foam?

Page 4 – Some love it, some hate it. Sometimes it’s there, sometimes it’s not. It’s not really an ingredient, but it’s an essential part of beer. What is it? Foam. So where does it come from and what does it do? Beer foam is obviously related to CO2, but there’s much more to this story.

• How Foam Forms A particular protein in malt – Lipid Transfer Protein 1 (LTP1) – is like a foam protector.
• When beer is poured, CO2 bubbles rise, along with hydrophobic LTP1.
• When the CO2 bubbles reach the surface, LTP1 forms a coating that helps preserve them.
• At this point, bitter iso-alpha acids from the hops connect with LTP1 and make the foam more stable, so it clings to the side of the glass.

It’s a simple equation: the more malt the Brewmaster adds, the more malt proteins are present. And the more malt proteins in the beer, the foamier it is. But the temperature and alcohol content of the beer, as well as the condition of the glass, also affect the thickness of the foam.

That’s why it’s so important to start with a clean, cold, wet glass. Wet and Dry Foam There’s a difference between wet foam, which is part of the beer, and dry foam, which consists of CO2 bubbles pumped in at the keg. The foam you see on Pilsner Urquell comes from the brewing process, not the keg. It’s a creamy, flavourful part of our beer and a necessity for the Pilsner Urquell experience.

A perfect Pilsner Urquell pour always includes a thick head of dense, wet foam. The foam protects the lager from oxidation, sealing in freshness and flavour. So next time you’re enjoying the world’s first golden lager, look for laces of white foam on the glass with each sip.

Is too much foam in beer bad?

Instead, Bakker recommends a more active pour that allows the bubbles to emerge in the glass and release CO2 before you ingest it. Foam, isn’t the enemy: a heavy topping of bubbles doesn’t damage the drinking experience —eventually those bubbles themselves fizzle into beer.

Does beer head get you drunk?

Does Beer Foam get you Drunk Faster? – Getting drunk faster by consuming beer head would all depend on if you actually drink it, how much you drink, and your body tissue composition. Much like the claim that champagne bubbles (also CO2) increase the effects of alcohol so to, is it claimed that the CO2 in the head of a beer and within the beer itself, results in alcohol being able to move from your small intestine into your bloodstream quicker.

1. This is likely true, but again – only in some people as determined by specific factors and body types.
2. There is no question, however, that the consumption of food will delay the emptying of the stomach into the small intestine, so definitely eating whilst you drink will slow down any traits of inebriation.

The Bowling Green State University in Ohio did a poignant study on Alcohol Metabolism that is quite relevant to this question and may give clarity on some of the aspects and is well worth checking out.

How big should the head be on a pint of beer?

Step 3 – Get tilting and pouring – The most important thing to remember when pouring that pint is the tilt. Too little and your beer will have too much of a head, too much and your beer will have virtually no head. For the vast majority of beers, the magic angle to create the perfect liquid to foam ratio is 45 ° – exactly diagonal. Some beers like pilsners, helles and golden ales have more carbon dioxide than most. With these types of beer, straightening the glass too soon can still create too much foam. So, the best way to pour these is to keep the glass tilted for almost the entire pour, then tilt the glass vertically right at the end to create a head.

Why is my beer foamy but flat?

Foamy Beer Tap: How To Fix It There are many reasons you may be getting a lot of foam coming out your tap. Without being there to see your system setup and what you are doing it’s very difficult for us to give an answer as to why it might be. We’ve tried to cover the main ones below, along with what you can do about them.

Under carbonated – strange but true, if you are getting a lot of foam but it is flat when you taste it your drink may be under carbonated – let it sit for a day or so at the pressures recommended on, Over carbonated – if you are getting a lot of foam and the drink has carbonation when you taste it it may be over carbonated. You can adjust it by releasing some pressure, letting it sit for an hour then releasing some more pressure. Then set the regulator to the level recommended in the table on the to get the correct level. A warm glass or tap – Often the 1st pour will be foamy as the cold liquid with lots of dissolved CO2 loses the CO2 when it hits a warm surface like the inside of a tap or a glass. Keep your glass in the fridge or cool it with water before pouring if it’s warm. Keep your tap in the fridge if possible (like with our mini kegs), ensure any liquid lines outside a fridge are well insulated and ensure a font fan is blowing cold air inside the font to cool it if you have a bar top font. Pouring onto foam causes more foam – You will often see the bar tender at a bar put the glass under the tap after only a bit of beer has come through the tap and gone into the drip tray or they will pour out the bit in the glass if it is foamy before starting again. This is because if you have some foamy beer in the glass it causes the rest to foam as it pours onto it. Better to waste the first 30mls than have a whole glass of froth! Not enough beer line – Beer line is measured depending on it’s internal diameter. We provide minimum 1.5m of 4mm internal beer line with our kegerator packages etc as this is the length needed to slow the liquid enough that it pours well when it reaches the tap, if you cut it short and don’t have a flow control tap it will pour to quickly and cause foaming. Too much pressure – If your pressure is set too high the beer will flow too fast and cause it to be agitated and foamy when it pours. If you have a flow control tap or a kegerator with correct length lines you should set your pressure at the recommended one from the, Too little pressure – If your keg has too little pressure in it it will cause the dissolved CO2 to free itself from the liquid. This causes gas bubbles in the beer lines or tap. If you can see bubbles in your beer line this is a likely cause. Your beer may also be pouring heady but flat as it is becoming under carbonated due to not enough pressure to keep it carbonated. Beer hasn’t settled – If your keg has just been filled from a tap, then driven home, carried inside and plonked on the table it has been shaken, agitated and been through temperature changes. It will pour foamy unless you let it sit for at least 30min. We had someone wonder why their 50L keg was pouring foamy after rolling it from the pub to car, car to a speed boat, boat to party on an island and then tried to tap it 15min later. An interruption in the flow – This is something more equipment based you can look for if you think everything above is correct. A rough edge inside a hose where it was cut, a steel burr inside a tap etc. will interrupt the smooth flow of liquid and can make it pour foamy

Why does my beer always foam over?

The Magic of Beer and Magnets December 16, 2014 Beer foam is a noted fun-killer. Few things ruin the enjoyment of a cold one more than having your hands and clothes drenched in your drink. But now, Belgian food scientists have found a way to prevent this party-foul: with magnets! So what causes a freshly opened, unshaken beer bottle to overflow? The main culprit is a protein called which dwells within the drink.

1. Hydrophobins are created by a fungus that infects malt grains during the brewing process, attracting carbon-dioxide molecules within the beverage to the surface.
2. Too many carbon-dioxide molecules at the beer’s neck can cause the bottle to bubble over when it’s opened,,
3. This spontaneous foam overflow, called gushing, is a different process than what produces a frothy foam head in a freshly poured glass.

To thwart the hydrophobins, brewers add extra hops into the mix. The hops, in addition to giving beer a bitter taste, act as an antifoaming agent that prevents the proteins from binding with carbon dioxide. But even with extra hops, beer can still erupt like a sudsy volcano.

• The Belgian scientists decided to try magnets after noticing that magnetic fields can disperse particles and help emulsify mayonnaise.
• So the team brewed a batch of beer in the Belgian and after adding in the hops, passed the concoction through a glass tube that had a magnet wrapped around it.
• What they found was that when the brew passed through the magnetic field, the hops broke apart and spread throughout the beverage, effectively increasing their surface area.

With more surface area, the tiny antifoaming particles bound with more hydrophobins than whole hops could, the team reported in a paper set to appear in the January edition of the, After the brew was complete, the team found not only that magnetized beer produced less foam, it only took a minute to achieve the results.

Why does my beer head disappear so quickly?

Foam on some people’s beers seems to disappear faster than on others’. Is it something in their breath? Valentyn Volkov/Getty Images/iStockphoto The question I notice that foam on beer seems to disappear quicker for some people more than others (and not just because they drink faster!). Does this have to do with breath, stomach acidity? The answer Indeed it does do that – but my guess is that the answer lies more in the glass (or your lip gloss) than in the drinker’s gastrointestinal system.

• The foamy head on many styles of beer is prized by the cognoscenti.
• The science is worthy of (and probably has been responsible for) a few PhD theses.
• It has much to do with the chemical structure of proteins and hops, but the difference from one glass to another, when we’re talking about the same beer poured from the same keg or bottle, mostly concerns factors external to the brew.

Those glorious suds can be slayed by a variety of factors. As a sworn enemy of dirty or poorly rinsed glassware, I would speculate that the main culprits are dirt and soap. Foreign residue in a less-than-pristine glass can interfere with foam’s chemical structure, leaving you with a headless brew.

• But, as you hypothesize, the drinker may play a role, too.
• Waxy, oily components in, say, lipstick can do the same.
• I’m not discounting the possibility of saliva “backwash,” either, as unsavoury as that is to consider.
• But if you sniff your (foamless) brew and it smells like soap, don’t hesitate to politely let your server know.

You might just score yourself a free pour in a cleaner glass. The Flavour Principle by Lucy Waverman and Beppi Crosariol (HarperCollins) won top prize for best general English cookbook at the 2014 Taste Canada Food Writing Awards. your wine and spirits questions to Beppi Crosariol.

It’s time once again for a new installment of Homebrew 101, our blog series written by Collin Corcoran, our Senior Print Designer. Collin recently started all-grain brewing and wanted to document his progress to share with our readers. In the previous installments he’s written about building a mash tun, making a yeast starter, mashing in, and boiling,

Today’s topic: bottling! Let’s get started. The first thing you have to think about when it’s time to bottle your brew is the bottle itself. Choosing the right bottle for your needs is key, so you have to spend some time figuring out how you want to store and serve your beer. My goal was to have my homebrew readily accessible and easy to transport so I could take it over to friends and relatives houses to share.

I chose the classic amber beer bottle (11.2 oz./330 mL), This style is exactly what you get with your standard six or twelve pack you see on store shelves. The amber colored bottles deflect most light away from your precious brew, which is important because the UV rays in light will really hurt the quality and freshness of your beer. Preparing your bottles for bottling day is very easy. You want to clean them thoroughly until they sparkle inside and out. I have found that soaking your bottles in an oxygen-based cleaner for about an hour will strip off any old residue or bacteria, but if they are really nasty – maybe because of some leftover yeast sediment from previous brews – you will need to scrub out the residue with a pipe cleaner and re-soak in your oxygen based cleaner, But before you actually start bottling, you have to add priming sugar to your beer so that it’s properly carbonated. Depending on how much carbonation you want, the level of added sugar will vary. Check out the pros over at Brewer’s Friend for a handy-dandy calculator.

For my Genesis IPA recipe, I used ¾ cup of Homebrew Brewer’s Crystals to reach the level of carbonation I wanted. Once you determine how much priming sugar you need, combine it with two cups of water in a small pot, then boil on your stove. When it reaches a rolling boil, turn off the heat, and let it cool down completely.

Once it’s sufficiently cooled off, add the sugar solution to your bottling bucket. Then, transfer your fermented beer into the bucket on top of the priming sugar solution to ensure even distribution of the sugar throughout your beer – in other words, an equal carbonation level in every beer. Now that your beer is primed and ready, it’s time to get down to bottling. You already have clean bottles on your bottle tree, so basically, all you have to do is grab a bottle, fill it up, and repeat until done. Be sure to leave about 1½ inches of headspace to allow room for the carbon dioxide that builds up while the yeast works on the priming sugar.

If you leave too little headspace, you may end up having beer bottles exploding due to the gasses having nowhere to go. Helpful Tip: while you’re filling your bottles with beer, you should also fill up a container with sanitizer solution, and let your caps soak for about 10 minutes before you start capping individual beers.

This ensures there is no bacteria slipping into your precious brew. With the beer in the bottles and the caps sanitized, it’s time for the final step: capping! It’s important that you find a flat, sturdy surface for your capping because the last thing you want is any spills or accidents at this late stage in the game.

The capper device I purchased is called an Emily Wing Capper, It’s very easy to use (self-explanatory really), and it works efficiently on any sturdy surface. On bottling day, I asked a buddy to come over to help speed up the process. As I was filling bottles, he was capping them off, and when all was said and done, it took us about 20 minutes to fill and cap everything.

Once your bottles are all filled and capped, the final waiting game begins. Typically, it takes about two weeks for your brew to become properly carbonated. When those two weeks have passed, you’re ready to enjoy your brew! So that’s basically the whole process.

1. I really hope that you’ve learned something – I know I sure have! When I set out to brew my Genesis IPA, I was excited about the world of possibilities in front of me, and it’s my sincere hope that you feel the same way as you’re getting started on your homebrew journey.
2. We’ll have one more installment of this blog series coming up later this week, where I talk about the experience I had entering one of my homebrew in a local contest.

As always, if you have any questions, please feel free to reach out through the comment section below or on the KegWorks Facebook Page, Thanks, everyone!

How much head is acceptable on a pint?

The law – In the UK, draught beer must be sold by reference to quantity and normally in quantities of half a pint or multiples of a half pint. It is one of the few imperial measures that are still allowed to be used following metrication some time ago.

The normal quantity of beer asked for in pubs across the City of London is a pint which is measured into a pint glass that bears a stamp to show it is an accurate measure. Most pubs use what are termed brim measures – this means that they contain a pint when full to the top. A few pubs may still use glasses that are called line measures – these are slightly over-sized glasses that have a line near the top to show the level of one pint.

Even fewer pubs may use what are called ‘beer measuring instruments’ that accurately dispense beer into a glass in multiples of a half pint. One of the problems with using a brim measure for the sale of beer is that it is virtually impossible to get a full pint of liquid due to the frothy head that is formed when the beer is dispensed into a glass.

1. Over the years, the generally accepted norm is that a pint containing a minimum 95% liquid and 5% head is OK.
2. However, this is a legally complex area and if you ask for a pint, perhaps you should really expect to get a full pint of liquid.
3. As part of this project, a legal opinion has been obtained from experts at Gough Square Chambers.

In an ideal world, all pubs would be required by law to use line measures, making it far easier to get a full pint of liquid. However, no such legislation currently exists and pubs can legally use brim measures.
