How Do You Make Sour Beer? - Información de la cerveza

Sour beer is typically produced through mixed fermentation : either exposing wort to microbes from the air for a spontaneous fermentation or pitching brewer’s yeast, brettanomyces, and bacteria together, and then waiting a long time to see what happens.

How do they make sour beer?

WHAT IS THE PROCESS OF MAKING A SOUR BEER? – There many ways to make sour beer, but the most common methods involve brewing the “wort” (unfermented beer), then introducing acid-producing bacteria either naturally by exposing wort to the open air or by adding a bacterial culture.

The fermenting beer is then held in stainless steel tanks or oak barrels for several months (or even years!) while the slow, steady bacterial fermentation takes place.
During this time, the brewer may choose to add other ingredients such as fruits or spices to achieve a desired flavor.
Once the brewer deems the beer ready, a variety of barrels are selected and blended together into a single tank.

The finished blend is then packaged into bottles and kegs for consumption.

What is added to beer to make it sour?

Sour Beer: how is it made? – Allagash Brewing Company There are a variety of ways to get sour flavor into a beer—and an almost endless variety of beers that you can add sourness to. To be clear, we’re honestly not the hugest fans of the term “sour beer.” For us, sour is a flavor descriptor and not a beer style.

Sour beers can be dark, fruity, light, heavy, anything really. But that doesn’t answer the question: how do you make a beer sour? In pretty much all sour beers, you’ll find lactobacillus, pediococcus, or both. Both are souring bacteria that each add a different layer of sourness to the beer. How those two bacteria, or just one of them, make their way into the beer is what differentiates one sour beer from another.

At Allagash, there are four main ways that we give our beer that sour flavor profile.1: Add Lactobacillus and Pediococcus. The most direct route for us is adding these two bacteria to our beer manually. You’ll recognize lactobacillus as the same bacteria that gives yogurt its tartness.

Pediococcus serves to add another layer of tartness and flavor.
While yeast produces alcohol and carbonation, lactobacillus and pediococcus produce acid, creating tartness.
There are a couple ways of adding these two organisms to your beer.1: you can add a culture of lactobacillus and pediococcus to the beer.2: You can add a portion of “old” beer that already contains these two bacteria.

That small portion of beer will serve to create acidity in a new batch.2: Put the beer in a barrel. But not just any barrel. You’ll need a barrel that previously held a tart beer. An unused oak barrel, a wine barrel, or barrels that once held spirits like bourbon or rum aren’t going to magically turn the beer sour.

What happens in a barrel that previously held sour beer is that the souring bacteria (lactobacillus and pediococcus) actually finds a home in the barrel’s wooden staves. Even after cleaning out an emptied barrel (as we do for all the barrels we plan to re-use) that souring microbiota goes on living deep in the wood.

Thus, the next beer that goes into the barrel will eventually come in contact with that bacteria, which will then make that new beer sour. 3: Add fresh fruit to it. The key here is that we have to add actual fresh fruit. Souring bacteria like lactobacillus and pediococcus naturally live on the skin of fresh fruit. So we can take a non-tart beer and just by adding, for example, fresh cherries to it we’ll eventually have a tart beer.

The added bonus to this method is that you’re getting fresh fruit flavor in your beer as well! We use,,,, and more in our beer.4: Spontaneous fermentation. Think of this as the “sourdough” method of brewing beer. Instead of physically adding yeast or bacteria to beer, we send the unfermented beer (known as “wort”) out into an open vessel called a coolship.

In that vessel, the wort is introduced to all the microbiota floating in the air. After spending an evening outside, the beer is put into oak barrels where that melange of microorganisms gets to work, adding tartness to the beer while also fermenting it. You may have heard the term “kettle souring.” That’s not something we actually do at Allagash. In a kettle-soured beer, the brewer adds the lactobacillus before fermentation. More specifically, they add it while the beer is in a brewing vessel called the “kettle.” Thus the name “Kettle Souring.” By adding the bacteria at that point, the brewer is able to sour the beer in a matter of hours rather than months.

What you’re not able to get with kettle souring are many of the subtle and complex flavors beyond just tartness. In a kettle-soured beer, you’ll find a simpler, one-note acidity. Like everything else in brewing, neither method is “better” than the other. It simply comes down to what the brewer is looking for in their beer.

If they want that clean kettle-sour tartness for a gose, they can go right ahead. If they want something more complex, then they have barrels, fruit, spontaneous fermentation, and more at their disposal! One more note on souring, and this concerns a method that we think of as a bit too much of a shortcut.

: Sour Beer: how is it made? – Allagash Brewing Company

What is sour beer made from?

Beer aisles and bar menus have no shortage of popular styles like hazy IPA or crisp lager, But maybe you need to change it up, give your tastebuds a little surprise. A sour beer, like a summertime glass of lemonade, might just be the pleasant pucker you’re after.

Sour beer is a broad category, with various substyles that all give special attention to the acidity level a drinker will perceive. That tartness, if it’s slight, can be pure refreshment. You’ll also find sour beers that stop you in your tracks — cheeks collapse and eyes squint. Craft brewers make all kinds, and you’re bound to find your favorites.

How sour beers are made can vary, but they all depart from the standard yeast strains of most ales and lagers, which require highly sterile environments. Sour beers opt for “wild” yeasts, and they also welcome friendly bacteria like lactobacillus, which you find in common groceries like yogurt or sauerkraut,

How hard is it to make a sour beer?

Give It Time – Patience is a virtue, especially with wild yeast. One thing you’ll need to know going into your first sour beer is that you’ll need to give it time. Lots of time. Plan on fermenting this beer in secondary for at least 6 months, and it will continue to develop in the bottle for years after that.

What is a true sour beer?

What Is Sour Beer? – As its name suggests, sour beer has a distinct sour, acidic or tart taste. Essentially, “sour beer” refers to any beer that tastes especially acidic and lively. By including fruits like raspberry, cherry and peach, sour beers can create the perfect balance of sweet and sour flavors.

Unlike other beers, sour beers use wild bacteria and yeast during the brewing process to achieve a tart, crisp flavor.
The microbes most commonly used to create sour beer are the bacteria Lactobacillus and Pediococcus, while Brettanomyces is often used to add acidity.
Adding fruit can also give sour beer a more tart taste thanks to the organic acids found in most fruits, such as citric acid.

The wild organisms used to sour beer can bring a wide range of flavors from intensely sour to light and fruity to downright funky. More well-known types of beers use specific yeast strains in a sterile environment to maintain tight control over the brewing process and produce more familiar flavors.

Do sour beers use hops?

Brewer: Tomme Arthur, Port Brewing in California (Solana Beach, San Clemente and Carlsbad). – When it comes to making Belgian-style sour beers, we employ several different kinds of malts with each malt providing certain foundations. In our Cuveé de Tommé, a Belgian-style dark strong ale, we are looking to support the bourbon barrel character and the strong charred oak flavors by adding a nice caramel malt base.

In our Le Woody Blonde Belgian Style Ale, we attempted to brew a beer with a lighter body and therefore chose no crystal malt, opting to use Vienna malt and flaked corn instead.
Hops play an important role in sour beers.
There are many compounds that are found in new hops that are not desirable in sour beers.

When the hops are aged, those compounds fall to reduced levels. The role of hops in sour ale beers is to provide not bitterness but other acids in a supporting role. We use a process of adding pure isolated cultures to our brews at specific intervals. It is in this way that we can control and best manipulate the finished beer.

Numerous isolated cultures are available to the homebrewer through Wyeast and White Labs.
Other homebrewers and some professional brewers are using dregs of yeast cultured from lambic beers.
These cultures contain Pediococcus, Lacto-bacillous and Brettanomyces.
The only drawback to using these types of mixed cultures is the inability to separate each type of fermentation.

All of our soured beers start with conventional primary fermentation before proceeding to a barrel where the real magic takes place. We ensure through the primary fermentation that we have hit our target levels of alcohol, bitterness and attenuation before proceeding to the barrel.

For a homebrewer, no extra special equipment is needed.
While oak is desired for its oxygen transporting abilities — and widely used in commercial brewing — plastic is an acceptable substitute as it has a permeable membrane allowing oxygen transport as well.
If plastic buckets are used, oak chips can be added as a flavoring compound that also provides some tannins.

We add our souring culture (mostly Pediococcus and Brettanomyces) after a one-month primary fermentation. The goal of this fermentation is to attenuate the beer to the proper level and then settle out as much of the yeast from the primary as possible.

Why are sour beers so good?

Why Are Sour Beers So Popular in 2022? — Iowa Brewing Company When you think of beer, sour beers probably aren’t the first thing that comes to mind. But sour beers are actually one of the most popular styles right now, and there’s a good reason for that.

They’re delicious! And there are so many different types of sour beers available, there’s bound to be one you love.
In this post, we’ll take a look at why sour beers are so popular today and why they’re so unique.
But first, what is a sour beer? Sour beers acquire their fun flavor from a unique brewing process that uses wild bacteria and yeast.

Whereas other types of beer, such as IPAs, use controlled yeast strains to produce more familiar flavors. All of these bacteria eat sugar like traditional brewer’s yeast, but their production of lactic and acetic acids cannot be replicated by the controlled strains of yeast. Science aside, after years of experimenting and sharing tactics, many brewers have now perfected the processes to produce enough of the sours brew to keep up with growing demand. Across breweries that produce it, is quickly outselling other forms of craft beer like pilsner, stout and lager, with sales second only to IPAs for most breweries.

Because it offers beer lovers something new to try and appeals to those who don’t consider themselves beer drinkers, sour beer has become a craze.
Sour beer is comparable to wine in its method of preparation — both are blended and can be aged in oak barrels — and in the way it balances its sweetness with acidity.

Many sour drinkers find the tasty beverages more approachable than traditional beers because they’re lower in alcohol content and therefore less filling. They also tend to sell better during the hot and humid summer months when other types of dark beer are considered too heavy to drink.

While most sour beers finish between 3%-5% alcohol by volume (ABV), some can be as high as 8%-9% or as low as 2%.
The ABV of a sour depends heavily on the style of sour and the individual beer’s brewing conditions.
Because sour beer generally has a lower ABV compared to others on tap, most sour beers can be considered a session beer.

This includes any beer that is lower in ABV and high in refreshment, so you can enjoy multiple in a single sitting. With the fruited sour scene exploding over the last several years, brewers are pushing the boundaries of their creativity to come up with new exciting, unique recipes to keep drinkers coming back.

What yeast is used in sour beer?

Homebrewing: Introduction to Sour Ales Sour ales are one of the biggest things in craft beer right now. The style that started out as a niche Belgian import not too long ago has spread like wildfire across American bars and breweries. Producing sour beer at home can be difficult, but with some experimentation and education there’s nothing stopping a homebrewer from creating a tart and funky ale just like the best of the commercial brewers.

The word “sour” in the beer lexicon covers a broad spectrum of flavors. It can mean a puckering tartness in a Geuze such as Lindemans Cuvee Renee, or a mild sweet and sour combination in a beer like Monk’s Cafe Flemish Sour Ale. The term is even used to refer to beers that may not be sour in the traditional sense, but instead have rustic flavor qualities that might remind you of wet hay or leather.

The common thread in all sour ales is the ingredient used during fermentation. While all beer ferments using varieties of yeast known as Saccharomyces cerevisiae, a sour ale fermentation includes different species of yeasts and even some types of bacteria.

The yeast that can be used in sour ales is called Brettanomyces, and the most common bacterias used are Lactobacillus and Pediococcus.
These fermenting critters, affectionately called “bugs” in the brewing world, eat sugar just like regular yeast.
The difference is that they produce lactic and acetic acids that cannot be made by the usual yeast.

These acids, along with other flavor compounds, provide the tart and rustic flavors associated with sour ales. “a sour ale can take months to ferment and is typically aged for one to three years.” Fermenting beer with sour bugs can be very different than fermenting non-sour beer.

The most notable difference is the time commitment.
While a standard homebrew typically ferments in one to three weeks with a few more weeks of aging, a sour ale can take months to ferment and is typically aged for one to three years.
This aging process allows the sour flavors to develop, and smooths out the harsher flavors that can be produced by the exotic bacterias.

Historically, most beer produced before the use of stainless steel probably had at least some level of sourness. Sour bugs live quite comfortably in the staves of wooden barrels that were used to store and age ales. When a barrel was filled with a new brew, the bacteria would transfer to the liquid, eat the leftover sugars and then wait for the next batch of beer to be made.

If a beer was consumed quickly, the sourness may not have been noticeable.
Brews with a higher alcohol or hop content would also hold off the bugs for a longer period of time.
Since Brettanomyces and sour bacteria live so comfortably in wood, modern commercial brewers who are intentionally making sour ales will often age them in oak barrels.

This creates a natural habitat for the bugs to work. Some of the bacteria will produce more acid in the presence of oxygen, which can permeate an oak barrel much easier than a stainless steel fermentor. Homebrewers who are brewing sour ales can mimic the commercial oak barrel techniques by adding oak chips in the carboy.

The bacteria will find its way into the oak chips in one batch, and they can be transferred to a second carboy to pass on the souring bacteria from one batch to the next.
Brettanomyces, or Brett for short, is the most common yeast used when making a sour ale.
It can produce some very funky flavors that some homebrewers describe as “horse blanket”, but I prefer to call rustic.

These flavors pair quite well with the sour characteristics you will get from the bacteria used to produce sour ales. Using Brett on its own will not make a beer sour, but this yeast will always make a very dry beer with a very low final gravity and funky flavors.

Brett is actually able to eat more complex sugar than standard yeast, but it tends to be a little slower.
A common technique is to add a standard beer yeast and Brett to the fermentor at the same time.
The regular yeast will ferment as much as it can at the beginning, and as it slows down the Brett will take over and finish the fermentation.

In some cases, Brett is added after the primary fermentation is complete. The Belgian Trappist beer Orval is known for this technique, where the brewers add Brett to the beer just as it’s being bottled. In this case, the yeast actually continues to change the flavor of the beer in the bottle for years, which is why a 5 year old bottle of Orval will taste very different from a new bottle if you try them side by side.

Brettanomyces is available to homebrewers from both White Labs and Wyeast. Lactobacillus is a bacteria that produces a distinct tartness in the form of lactic acid. The variety used in brewing is closely related to the Lactobacillus used in making cheese, but it’s not exactly the same species. This sour bug is prominently exhibited in the sour German wheat styles Gose and Berliner Weiss.

It’s a very temperamental bacteria that does not propagate in beers with even a mild hop content or alcohol above 4% ABV. Homebrewers can buy Lactobacillus in most homebrew shops, but the use should be limited to styles that call for the bacteria specifically.

Pediococcus is a tenacious souring bacteria that also produces lactic acid and tends to make a lot of the buttery flavored compound called diacetyl.
It is typically used in conjunction with funky and rustic flavored Brettanomyces.
You can find Pediococcus in the bottom of bottles of the classic Belgian sour ales made by Cantillon.

This bug is less common in homebrewing stores, but it is produced by Wyeast and it’s available from White Labs in a blend of sour bacteria. Homebrewers should take extreme caution when using Pediococcus, since it can easily infect equipment and wreck other brews that are not supposed to turn out to be sour.

Are sour beers real beer?

Is Sour Beer the Same as Beer? – While sours are called “beer,” they are actually quite different than other types of beer, Sour beers typically do not use traditional brewer’s yeasts (like saccharomyces cerevisiae), and most are not brewed in a sterile environment. In fact, many Belgian brewers still encourage wild yeast strains and bacteria to infiltrate their sour brews by cooling their wort (unfermented beer) outdoors.

Is sour beer a lager or ale?

What’s the Difference Between Sour Beer and Saison? – Sour beers may be either a lager or ale, while Belgian saisons are ales. The two beer styles tend to be equally refreshing and highly carbonated. Depending on the brewer’s approach, saisons might have a slightly tart taste, but they are generally not as puckery as sour beers.

A variety of methods are used to produce sour beer. The common factor is the introduction of an acid-producing organism, which is responsible for producing the tart taste during fermentation. Saccharomyces is the standard brewer’s yeast species used to make beer. To create a sour-tasting beer, a wild yeast species called Brettanomyces (often abbreviated “Brett”) may be introduced to the wort,

Some brewers introduce bacteria like Lactobacillus and Pediococcus, which produce lactic acid (as in yogurt). There are also times when acetic acid is used or fruit is added during the second fermentation to impart a sour taste. When making a saison, the brewer may employ Brett, Lactobacillus, or a sour mash in the wort.

Mixed fermentation uses a combination of Saccharomyces and Brett along with bacteria.Wild fermentation may use Brett alone or pair it with Saccharomyces and is fermented longer than normal beer.Spontaneous fermentation can take years and relies on the natural organisms present in the environment or a beer’s ingredients.

Due to its untamed nature, brewing sour beer with wild yeast and bacteria is difficult to restrain. Many breweries choose not to dabble in wild yeast sours because it can contaminate beers that are highly controlled and throw off the entire production.

How much yogurt to add to sour beer?

Yogurt Souring – Mike Karnowski from Green Man Brewery Blueberry Berliner Weisse made from a yogurt starter Yogurt Souring refers to the method of souring wort using unpasteurized yogurt. Greek yogurt is often made with Lactobacillus acidophilus, Using cultures of L. acidophilus from yogurt reportedly can make a 3.0-3.5 pH sour wort in 24 hours, without producing vomit/fecal flavors and aromas.

To sour 5 gallons of wort with yogurt, make a 1 liter batch of unhopped starter wort the day before brew day.
Add 2-4 teaspoons of live yogurt to the starter wort.
Maintain a 100-110°F (37.8-43.3°C) temperature for about 24 hours.
On brew day, and after the 24 hour sour starter is finished, mash and sparge a low IBU wort as normal, boil for a few minutes, and then chill the wort down to 100-110°F (37.8-43.3°C).

Pitch the yogurt starter into the wort, and hold the temperature as close to the 100-110°F (37.8-43.3°C) range as possible. Bubbling CO2 through the wort is advised if possible to prevent potential off flavors, but is not required. Within 24 hours, the wort should be down in the 3.x pH range.

Boil the wort, adding any hops that the recipe calls for, yeast nutrient, etc., and then cool the wort down to Saccharomyces pitching temperatures.
Bob’s your uncle! Many strains of L.
Acidophilus, which is one of the more common species of Lactobacillus found in yogurt, produce toxins that can kill other species of Lactobacillus,

See Lactobacillus bacteriocins for more information.

What is the best base for a sour beer?

Creating the Right Environment – My specific approach to fast-souring, more than anything else, is about taking steps to ensure that flaws that can ruin a sour beer don’t appear in the final product. In the context of industrial beer production, pretty much everything about making sour beer is wrong.

Sour-friendly bacteria can ruin your average IPA or light lager.
The wild yeasts used for sour beer can literally make bottles explode due to excessive carbonation.
These are both justifiably regarded as contaminants.
As a result, making delicious sour beer is about controlled contamination, in a way that maximizes the characteristics we want—lactic acidity in balance with malt character, some supportive fruity esters, a dry finish—while minimizing those we don’t—vinegary acetic acid, sweaty/buttery fermentation byproducts, and cloying residual sugars.

For fast-souring, I always make a Berlinerweisse as the base style for two simple reasons: one, it’s low in alcohol (often below 3% ABV), and two, it’s very simple in flavor. The low alcohol content gives bacteria the best chance to convert as much of the sugar to lactic acid, as opposed to alcohol, as possible.

What is the hardest beer to make?

Light Beers – Light beers, such as light lagers or ales, pilsners, or Helles, are the most challenging to brew due to their subtle flavor profile, Mistakes during the brewing process are highlighted in the final product, usually in the taste, but may also appear in aroma and appearance.

What is a Belgian sour beer?

More info Tradition: Before mid-19th century advances in refrigeration, almost all beer was, to some degree, sour due to natural fermentation and aging, resulting in tart and funky flavors and aromas. Belgian Sour Ales offer a delicious window into this past, as today’s brewers of traditional sour ales still rely on patient aging and careful blending for complexity and balance.

Is Guinness a sour beer?

Key finding #1 – Guinness does use a sour blend for their stout – No ratios or processes were described, but the brewers did cop to the fact that part of the key feature of Gunniess Stout was a sharp acidity contributed by lactic acid. A simple fact of brewing history is that almost every beer before the late 1800’s was populated with all sorts of non-saccharomyces organisms; since Guinness has been brewing for such a large span of history it’s to be expected that a bit of that “infected” character is a part of the recipe.

My hypothesis, however, is that Guinness uses food-grade lactic acid instead of a separate sour mash (or other souring operation). Perhaps you’ve seen this quote around: ” they have a series of huge oaken tuns dating back to the days before Arthur Guinness bought the brewery, which they still use as fermentors for a fraction of the beer.

The tuns have an endemic population of Brettanomyces, lactic acid bacteria and Lord knows what else, and beer fermented in it sours emphatically. They pasteurize this and blend small quantities of it with beer fermented in more modern vessels. ” (confession: I don’t know the attribution of this quote, but I’ve seen it repeated extensively), but I don’t think there’s much of a chance of anything other than saccharomyces being in the new brewhouse.

What is German for sour beer?

German Sour Ales – Whiteys Liquors Gose (pronounced Go-suh) is one of the oldest styles brewed, dating back till at least the 11th century A.D. Originating in the mining town of Goslar, Gose is a mild, sour, and salty beer with exceptional complexity and drinkability, owing to its low alcohol content and dryness.

The salt and mineral content of the water in Goslar were responsible for the initial saltiness of the beverage, while a lactic top-fermentation gives the beer its tartness. As the mines of Goslar gave out in the late middle ages, production of Gose migrated to Leipzig, where by 1900 it was the most popular beer style in Leipzig, and there were over 80 distinct gosenschenke (Gose-Taverns).

The beer was sometimes served fortified with Cumin liquer or caraway schnapps, lending more flavor and a stronger alcoholic kick to the beverage. Unfortunately the 20th century was not kind to this beverage. The lager craze was sweeping the world so that many breweries were beginning to transform into lighter beer producers.

Almost all beer production ceased entirely during World War II, and after the smoke cleared from the war, Leipzig found itself in the communist half of Germany, where all barley production was diverted to making bread rather than beer.
The last Gose brewery was confiscated and closed by the state in 1945.

Leipzig’s Friedrich Wurzler Brauerei revived gose in 1949, but when the owner died in 1966, so did the style. So the style of Gose lay dormant until the 1980s, when it began to make a comeback with the revitalization of Ohne Bedenken, once one of the city’s most famous gosenschenke.

What beer is closest to a sour?

From Wikipedia, the free encyclopedia Norwegian sour beer aged for eighteen months in oak barrels with Lambic microbes Sour beer, also known as Sours, is beer which has an intentionally acidic, tart, or sour taste. Traditional sour beer styles include Belgian lambics, gueuze and Flanders red ale, and German gose and Berliner Weisse,

Are sour beers high in sugar?

So What’s The Truth Behind Sour Beer Calories? – “All things being equal, sours could be perceived as being more dry, having lower carbohydrates, and more ethanol because pure carbohydrates (C-H bonds) have more calories than mixed C-H-O bonds as they’re already partially oxidized,” says Peter Oates, co-founder of Equilibrium Brewery in Upstate New York. So a sour beer might have fewer calories than another beer style, but only if it has less sugar. And many of today’s sours — which are loaded with everything from fruit purée to unfermentable milk sugars — are filled with sugar. “We do mostly kettle sours, and something like a traditional Berliner would use less grain than most beers,” said Sean Biby, brewer at Grist House in Pittsburgh, Pennsylvania. When you consider the rise of adjuncts or additives in beer, you see that fermentable sugars from grain aren’t the only way to add calories to a beverage. From marshmallow and fruit purée to lactose and waffles, any calorically-dense item you put into your beer is going to increase the calorie count.

What is a fun fact about sour beer?

The second Saturday of September is Sour Beer Day! In honor of this quirky beer, here are some of the facts about this tart, sweet beer. There are six varieties of sour ales: American Wild Ale, Berliner Weisse, Flanders Red Ale, Gose, Lambic & Oud Bruin

Sour beer originated in Belgium but has spread across Europe and the US. Sour beers are made by intentionally allowing wild yeast strains or bacteria into the brew, unlike modern brewing that are produced in a sterile environment. The most common agents used to deliberately sour beer are Lactobacillus, Brettanomyces, and Pediococcus The tart flavor can also be accomplished by adding fruit during the aging process to push a secondary fermentation or microbes present on the fruit’s skin Sour beers come in a variety of colors: from pale ales to sours that almost look like porters or stouts Since wild yeast is unpredictable, the sour beer brewing process is extremely fickle and takes months to ferment and years to mature Because of the sour beer brewing process many breweries have a special sour brewing room or building for their sour beers permanently away from their modern brewed beers

Brettanomyces is available to homebrewers from both White Labs and Wyeast.
Lactobacillus is a bacteria that produces a distinct tartness in the form of lactic acid.
The variety used in brewing is closely related to the Lactobacillus used in making cheese, but it’s not exactly the same species.
This sour bug is prominently exhibited in the sour German wheat styles Gose and Berliner Weiss.

Pediococcus is a tenacious souring bacteria that also produces lactic acid and tends to make a lot of the buttery flavored compound called diacetyl. It is typically used in conjunction with funky and rustic flavored Brettanomyces. You can find Pediococcus in the bottom of bottles of the classic Belgian sour ales made by Cantillon.
