6 Reasons Why Copper Is Used for Distilling Equipment manufacturers know that copper isn’t just a pretty face. When it comes to copper distillation equipment, the copper also serves a useful purpose. Here are six reasons why copper is beneficial in the distillation process.1.
- Oldest Pedigree: According to, “Copper is man’s oldest metal, dating back more than 10,000 years.” Simply by virtue of the technology available at the time, copper would have been the metal of choice for producing all manner of implements used to make ancient man’s life easier.
- And, since the practice of spirits distillation is some two thousand years old, it makes sense that copper would be the material of choice.2.
Easiest Deformation: As luck would have it, this ancient metal allows for an easy process of changing shape as copper is very malleable. Therefore, very early on in history, it seems clear that the use of copper for different types of vessels was a logical choice, given the fact that production technologies of the time were limited.
For distilling purposes, one assumes the use of copper was largely predicated upon ease of use.3. Antibacterial Properties: Interestingly, copper can eradicate certain types of bacteria and fungi. Copper is commonly used for fungus control in all kinds of agriculture. It is also no surprise that copper piping really is the preferred material for residential and commercial water supply lines as copper is commonly used as an algicide for water purification.4.
Thermal Transfer Properties: For some miracle reason, no doubt, electrons can move freely through copper. These conducting electrons help copper be a very good conductor of heat (and cold for that matter). For spirits distilling purposes, applying heat and the removal of heat is a requisite.
- Copper does both very well.5.
- Volatile Sulfur Compound Removal: Less than optimal fermentation practices can lead to poor yeast health as fermentation works toward completion.
- Aside from copper’s antibacterial qualities, the characters of copper allow it to have a chemical reaction inside of to remove volatile sulfur compounds released by the yeast during fermentation.
These sulfur compounds can affect the final perceived quality of the finished product. The debate will forever rage on with respect to how much copper is needed in the vapor path to sequester sulfides. However, one thing is certain: you can’t have too much copper in the vapor path.
- Be warned.
- Though, using copper as a crutch for practicing less than optimal fermentation techniques is not going to produce an elevated spirit.6.
- Beauty: Last but certainly not least, copper is for some reason so compelling to look at.
- When shined up, it’s hard not to stare! Even when the patina has been fully developed, it’s hard not to stare! For some reason it’s almost therapeutic to stare at it.
It is mesmerizing. It is magical. Ready to purchase copper distilling equipment for your commercial distillery? You’re in the right place! carries a variety of copper still components. : 6 Reasons Why Copper Is Used for Distilling Equipment

Why do you need copper line for moonshine?
– Copper is the preferred material in the construction of a still to impart flavor into the distilled spirits. According to Broadslab Distillery, both stainless steel and copper are excellent conductors of heat: dispersing the heat evenly across the entire surface of the metal and creating a more even distillation.
- But where both stainless steel and copper will not put harmful chemicals into your final product, copper has the advantage over stainless in that whisky out of a copper still simply tastes better.
- When distilling in copper, the copper reacts on a molecular level with the sulfurs put out by the fermenting yeast.
It “cancels-out” the sulfur taste which would otherwise be bitter and not as smooth. In the process of distilling, the sulfur coming from the yeast binds itself to the copper, making hydrogen-sulfide which in turn, forms copper sulfate. The copper sulfate sticks to the inside of the still after distillation is completed.
Does alcohol react with copper pipe?
As mentioned Page 2 Recycled Paper 2 Please Recycle above, ethanol is not compatible with soft metals such as zinc, brass, copper, lead, and aluminum. These metals will degrade or corrode in contact with ethanol and possibly contaminate a vehicle’s fuel system.
Why not to use copper fuel line?
Cummins – Diesel Fuel Piping. Diesel fuel lines should be constructed from black iron pipe. Cast iron and aluminum pipe and fittings must not be used because they are porous and can leak fuel. Galvanized fuel lines, fittings, and tanks must not be used because the galvanized coating is attacked by the sulfuric acid that forms when the sulfur in the fuel combines with tank condensate, resulting in debris that can clog fuel pumps and filters.
Copper lines should not be used because fuel polymerizes (thickens) in copper tubing during long periods of disuse and can clog fuel injectors. Also, copper lines are less rugged than black iron, and thus more susceptible to damage. Note: Never use galvanized or copper fuel lines, fittings or fuel tanks.
Condensation in the tank and lines combines with the sulfur in the diesel fuel to produce sulfuric acid. The molecular structure of the copper or galvanized lines or tanks reacts with the acid and contaminates the fuel.
How do distillers avoid methanol?
2.1.3. Inhibition of Pectin Methylesterase by Sterilization of Mash – A significant reduction of methanol by 40–90% can be achieved by thermal deactivation of pectin methylesterase (often referred to as “mash heating”). There are various suggestions for temperature/time combinations to achieve the enzyme’s denaturation.
- Sterilization at temperatures higher than 70 °C was generally suggested to effectively prevent the production of methanol by inactivation of pectin methylesterase,
- Methanol can be reduced by targeted thermal deactivation of pectin methylesterase by heating the mash to 80 °C up to 85 °C for a holding time of 30 min or to 60 °C for 45 min,
Pasteurization at 72 °C for 15 s prevented the production of methanol in fermented plant beverages containing Morinda citrifolia (noni fruit), In cider spirit, the pasteurization (30 min at 50 °C, then heated to about 85 °C) of the apple juice prior to fermentation reduced the methanol content by 34–46%,
- Lower methanol levels were obtained in Williams and plums by heating the mash to 65 °C for 5 min, followed by re-cooling for fermentation,
- Xia et al.
- Confirmed that autoclaving by steam injection of the mash of jujube reduced the methanol content in the spirit significantly by a factor of about eight.
The authors also determined pectin methylesterase activity confirming that their treatment method reduced the activity to one-fifth to half of that without treatment. Further technological approaches for inactivation of methylesterase are thermosonication (ultrasound plus temperature at 70° led to 30% methanol reduction in plum wine) or use of microwaves (70 °C for 1 min led to 70% methanol reduction in plum wine).
Can you drink distilled moonshine?
Consuming Methanol In Moonshine – Upon first sip, the dangerous potential of methanol is undetectable. It will simply get people drunker. However, after it is metabolized, the methanol can have an extremely harmful effect in someone’s body.10 milliliters (ml) of methanol is all it takes to permanently damage the optic nerve and cause partial, if not complete, blindness.30 ml of methanol is lethal.
For reference, and standard shot glass in the United States holds 40 ml. If less than 10 ml of methanol is consumed then the worst someone will experience is a hangover, (albeit, quite possibly the worst hangover of their life). However, if someone consumes 10 ml or more of methanol, even split up among drinks, that can be enough to cause permanent damage or kill them.
While there are processes today to discard the toxic alcohol that is visually indistinguishable from water, some illegal Moonshiners will add methanol back in to provide a stronger potency. Obviously, without regulation, there is no way to know if illicit alcohol contains methanol.
Can you make moonshine with a stainless steel still?
How To Make Your Own Moonshine Still With a little soldering skill you can easily build your own moonshine pot still. There are five vital parts to your pot still:
Boiler Vapor Column Thermometer Condenser Collection Container
Boiler The boiler is used for heating up the wash / mash. A copper or stainless steel pot is all that is required for a boiler. Be sure to pick a pot that is large enough to hold your wash / smash. You also want to be able to create a tight seal around the lid of your pot to prevent the escape of alcohol vapors.
At MoonshineStillPro we have boilers with copper domes that can serve as a starting point for your own homemade moonshine still. Vapor Column Any still must contain an adequate air space inside to allow alcohol vapors time to separate from water vapors. A tubular still column is commonly used to provide this space as the height assists the separation of vapors.
Copper should be the primary metal used for creating your vapor column because copper reacts with the steam vapors making your spirits taste better. We provide a wide range of copper tube sold by the foot, ideal for creating a vapor column. Thermometer It is important to monitor the temperature in your still.
Alcohol vapors separate from the water vapors at 173 F. A thermometer is key to maintaining the proper temperature for distillation to occur. Condenser After the mash is heated in the boiler, the alcohol vapors pass up through the copper tube vapor column as steam and must be then cooled back into a liquid before exiting the still.
Most homemade stills use a tube within a tube water jacket type condenser for this purpose. These can be plumbed to any cool water source. A pump placed in a large container of water is commonly used. Alternately some distillers choose to employ a copper tube spiral known as a “worm” to function as the condenser.
The “worm” typically passes through a container of water which then cools the alcohol steam causing it to condense back into liquid form. Container for Moonshine Now that your alcohol is back in liquid form, have a receptacle to collect your homemade moonshine. Glass containers are the most common. Make sure you choose one large enough or have several available and switch out as each consecutive one is filled.
Mason jars have been the container of choice for many years. Now that you’ve learned the basics of how to make a pot still, you can get started with the fun hobby of moonshine distilling!

Is brass safe in moonshine still?

- Why you should never use brass
The use of brass is always a controversial topic, yet no matter how frequently it comes up people still ignore the very negative side effects related to using it in a still. This is something that is brought up so frequently yet no definitive answer, which I personally think is very important since were talking about something that can poison, cause cancer and cause long term health issues.
- Against use of brass. The risks are not worth the savings, and there is always a safe replacement for brass.
- People who are for the use of brass or believe the negative side effects are to minor to worry about.
- People who have no idea but read something somewhere. Generally they see popular still designs using brass and assume it is safe.
Personally I am against using any brass in a still or boiler besides for irrigation fittings used for cooling or for decorative and cosmetic needs. Copper or stainless steel parts are not much more expensive and remove all worries about the lead levels you would be exposed to. My main reasons for being against brass use are:
- There is always a safe option available.
- The only reason to use brass is because it is slightly cheaper then other options, or slightly more available.
- There is no way to know how safe (or unsafe) brass fittings you are using are, regardless of steps (pickling) you take to try to make them safe.
- Most brass fittings are not even safe for water use, which makes them even less safe for distilling use.
- It is irresponsible and a dick move to share spirits with friends or family without telling them about the chances of drinking leaded spirits.
To start here is the information from the EPA on “lead free”, and use of brass, and what is covered.1417(d), “lead free” means that solders and flux may not contain more than 0.2% lead. pipes, pipe fittings, and well pumps may not contain more than 8.0% lead.
So from the start we can all agree that lead free isn’t lead free. Its like “unlimited calls” or unlimited bandwidth”. Lead free still contains lead period. Only items used in water consumption and more specifically end points are required to have less then 8% lead. Non-end point components can have more.
The WORST Mistake When Soldering Copper Pipe (Not Deburring) | GOT2LEARN
This is important to know later on. Here are some important details from the link above that the EPA discuss and I want to address
- What are the sources of lead in drinking water?
- Can plumbing fixtures or devices containing 8.0 percent or less lead contribute lead to drinking water?
- Is there an NSF performance standard limiting the leaching of lead into drinking water?
The amount of lead attributable to corrosion by-products in the water depends on a number of factors, including the amount and age of lead bearing materials susceptible to corrosion, the way they were manufactured, how long the water is in contact with the lead containing surfaces, and how corrosive the water is toward these materials. The corrosivity of water is influenced by a number of factors, including acidity, alkalinity, dissolved solids and hardness. In general, soft acidic waters are more corrosive to lead than hard waters.
Yes, any plumbing device or fixture, domestically produced or imported, that contains any amount of lead and is in contact with the water is a potential source of contamination. Brass fittings and plumbing fixtures, containing 8.0 percent or less lead, have been found to contribute high lead levels for a considerable period of time after their installation, even in cases where these devices are in contact with relatively non-corrosive waters.
NSF Standard 61, section 9 covers “endpoint devices.” The NSF Standard defines endpoint devices as mechanical plumbing devices, components, and materials which are typically installed within the last liter of the distribution system and are intended by the manufacturer to dispense water for human ingestion. The devices include kitchen and bar faucets, lavatory faucets, water dispensers, drinking fountains, water coolers, glass fillers, residential refrigerator ice makers, supply stops and endpoint control valves. These devices are regulated under section 1417(e) of the SDWA. For details, refer to Part IV of this document. Products that are NOT COVERED under NSF Standard 61, Section 9 include in-line devices, point of use and point of entry water treatment devices, bath and shower valves, drains, backflow preventers, utility, laundry, bidet, self closing or electronic faucets, faucets with hose thread spout, and non lavatory hand wash stations.
- So now from the information above we know that:
- Lead free is not free of lead. In fact it can be up to 8% lead.
- Only end point brass used for water consumption needs to meet standards and do not need to meet these standards.
- Brass not used in end points can have more then 8% lead.
- Many of the components distillers may use that are brass are not end point fittings, so they are leaded brass.
- They only test water on specific conditions and temperatures for lead leeching.
- Acceptable temperature range for specifically designed hot water usage is only 180 degrees.
- High temperatures, and high acidic fluids leech more lead.
- Even “lead free” brass has been found to contribute high lead levels for a considerable period of time after installation.
Now you might be saying well all brass items that have high lead in them will be listed as such or have a warning right? Well not really. Here is a perfect example from the Home depot website, which does list some info, but you will not see this in the store.3/4 in.
x 3/4 in. Brass NPT Compression Fitting You might recognize this as something similar used in the potstill design in the side bar. In the product listing you’ll see “California residents: see Proposition 65 information ” listed in the overview. Prop 65 wants this item to be listed (only in California) “California’s Proposition 65 entitles California consumers to special warnings for certain products that contain chemicals above certain threshold levels.” The general Proposition 65 notice is as follows: “WARNING: This product contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm.” You know those brass valves you use in your Boka? Here is a listing from the EPA about valves: Are valves dispensing water from point of use treatment devices covered under the “lead free” definition of the SDWA? Point of use a water treatment devices are not covered under NSF Standard 61, Section 9.
Therefore only the 8.0 percent lead free criterion is applicable to them. Point of use treatment devices are tested and certified under NSF Standard 58. Thus, while EPA encourages the industry to conform with this standard, the industry is not currently required to do so.
In fact doing a google site search for homedepot.com and brass fittings California residents lists 65,800 listings. Additional information: Study of lead leeching of “lead free” and leaded brass Initially, the leaded-brass components leached about 8.5 times as much lead as the ‘‘no-lead” parts, and by Day 19, the leaded-brass were on average discharging about 14 times more lead.
It is likely that ultimately, as initially-available surface lead is dissolved, that the discharge may reach the 50 to 70 fold ratio New school built found their brass to contain up to 18%-20% lead, and 30 times the federal standards, and they specifically went into the construction with wanting to keep lead levels minimal.
One of the excuse I see all the time is that lead is not solvable or make it to your final product as long as it is not in your distillate path. But lead can have a major impact on your yeast, in both cell growth upwards of 50% decreases, as well as off flavoring. And if you use dunder or backset distillers can very easily transfer lead from their boiler to their next fermentation.
Additionally lead can have negative affects on yeast in both their cell growth (upwards of 50%) and cause yeas to generate off flavors. If you use backset or dunder you will pass lead from boiler to fermenter frequently. Summary:
- “Lead free” it not lead free.
- “Lead free” only applies to drinking end points, and the bulk of the brass distillers use in their stills are not end point fittings.
- Even “lead free” fittings produce quite a bit of lead, and leaded brass can produce 50X to 70X more lead.
- All this information relates to highly controlled and monitored water and low temperatures. We distillers use the equipment for highly acidic, hot, volatile alcohols and washes, which have an even greater affect on lead.
- Nearly every bass fitting has a safe to use counterpart for a few dollars extra.
All brass has lead. The amount of lead in specific fittings for a specific purpose (water consumption) have “acceptable” levels of lead after a period of time (weeks, months), but still require you to flush the water that has been in contact with the brass (which is why you’re supposed to run your faucet for a few seconds prior to drinking).
But not all brass fittings are considered safe as seen with California wanting warning labels on these items. And since there is no way to regulate, test or know for sure how much lead is used there are many cases of lead levels being insanely high. I say this all the time; you don’t see brass used in professional distilleries and as hobbyists following the best practices of professionals is something we should all strive for.
Making safe spirits should be everyone’s goals, and to save a few dollars to use brass is not an acceptable choice especially if you are not the only person drinking your spirits.
Are copper pipes good or bad?
Copper pipes have been the proven standard of reliability for over 50 years! They are not prone to leaks, are extremely durable, stay fitted tightly, have a long life span and can be recycled, are resistant to heat, and won’t pollute your drinking water.
Can copper pipes cause copper toxicity?
What is copper, and how does it get into my water? – Copper is a naturally occurring metal and is usually found in small amounts in natural spring water sources. It also occurs naturally in rocks, soil, plants, and animals. A small amount of copper is even essential to the human body and helps regulate certain bodily functions.
- Copper is easily shaped and molded, which means it’s become an excellent resource for electrical wiring, plumbing, and household fixtures.
- Furthermore, copper is added to some agricultural fertilizers and manufacturing operations, which can taint underground water sources used by households and municipal authorities.
This copper runoff can even find its way into streams and rivers, contaminating fishing and other food sources. Copper also tends to contaminate water sources when pipes corrode, leading to higher amounts which can cause copper toxicity.
Does copper react with fuel?
Now, copper interferes significantly in the gum content of gasoline, because it is a catalyst of radicalar oxidation reactions and it accelerates peroxidation. Therefore, this metal must be avoided in any metal alloy that comes into contact with gasoline in the feeding system of engines.
Can I use copper for an oil line?

What is the best material for fuel lines?
What type of fuel lines should I use? Fuel Lines can be made from many different materials. If you plan to race, be sure to check the rule book for your track or sanctioning body. Using the right material the first time will save you time, money, and headaches.
Why do they use copper water lines?
Other Piping Materials – As many of copper’s competitors are quick to point out, copper is an ancient material. There is no denying that. Copper has been used to deliver safe drinking water to civilizations for thousands of years. Copper has seen many “new” materials come and go over the past 2,500 years.
Through the late 1980s and 1990s, many municipalities trying to keep pace with the construction boom turned to various plastic piping systems for their water service line installations. Copper’s market share slipped from 75 percent through the mid-1970s to 50 percent of all water service installations by the year 2000, as municipalities turned towards the lure of lower cost.
However, as the building boom continued through the early 2000s, this trend began to change. Utilities and municipalities began to struggle with leaks and loss of water issues in plastic service lines. One-by-one, water utilities began to re-evaluate their material choice and in wholesale began to turn back to the reliability of copper.
By the end of the decade, the material trend reversed course and copper once again accounted for nearly 80 percent of all water service line installations. These were conscious decisions on material choice made one-by-one by individual water systems after careful analysis of benefits and costs in the absence of any marketing by the copper industry.
What makes this even more significant is that these decisions were made at a time when the cost of copper was on an almost historic rise, which indicates that utilities found reliability trumps short-term cost in their overall infrastructure investment.
Most of the knowledge on the health, safety and reliability of piping materials comes from long-term use and service. A history that plastics do not have. One of the reasons is that when problems develop in the use of one plastic—the plastics industry switches to a whole new plastic—solving one problem but starting the learning curve to the next problem all over again.
“New” equals “unknown.” Lead Pipes —once favored for their durability and ductility—were the go-to material for service lines, but are now known to pose potential health effects even at the lowest levels of exposure to the drinking water they convey.
- While it has been illegal to install lead piping since 1986, its use for service lines began to fade in favor of copper through the 1960s and ’70s.
- However, from the dawn of indoor plumbing in North America until its ban, lead was a common material for this use.
- Today, an estimated 6.1 million lead service lines remain in use across the U.S.
Unlined iron, steel and galvanized steel pipes are robust but hard to install without multiple joints that can leak, and are easily clogged with mineral deposits in many waters. Plastic pipe is not constructed solely of a single polymer compound, but rather is a combination of plastic polymers and other agents like chemical stabilizers, antioxidants, heat stabilizers, plasticizers, etc.
To give the plastic compound necessary properties and protection. This makes plastic pipe vulnerable to leaching these additive compounds. Plastic pipe has been shown to leach a number of organic substances known to be harmful to human health. Copper leached from copper drinking water tube is a natural and essential nutrient to human health in small doses.
Plastic drinking water pipes can emit more than 150 Volatile Organic Compounds (VOCs), many of which are known to be harmful to human health. They can cause dizziness, vomiting and chronic illnesses, including cancer. Some Volatile Organic Compounds (VOCs) from plastic pipes generate unpleasant odors and potentially harmful vapors.
Early PVC plastic pipes became brittle when left exposed to UV light or chlorine in the water system and, were found to leach vinyl chloride monomer, a known human carcinogen. Polybutylene plastic pipes experienced wholesale failures in building plumbing systems due to embrittlement and stress fractures. Polybutylene service lines experienced significant, widespread embrittlement and stress fracture failures in teh late 1980s and early 1990s and were removed from the market. Their era of use was short and the inventory of installations small compared to the overall in-ground service line infrastructure. Polyethylene service lines are being removed by the thousands due to oxidative damage from chlorine and other disinfectants in drinking water. Polyethylene and PEX plastic systems have also been shown to leach various chemicals to drinking water, with unknown health effects, resulting in taste and odor issues. PEX releases methyl tertiary-butyl ether (MTBE), an organic compound, which the EPA lists as a toxic substance. Standards for MTBE have not yet been set nationally, although some states have set their own limits. Other plastics: new polypropylene plastic systems are beginning to show failures due to interactions with copper and other chemicals present in water systems.
What is copper mesh used for in distilling?
How to Clean Copper Mesh Copper mesh is used to reduce or eliminate sulfur compounds during beverage-grade distilling. It requires modest, yet regular cleaning to ensure its effectiveness and maintain the integrity of your still’s operation. Make sure to use pure copper, quality matters. Pure copper will not rust, contaminate, or scratch surfaces, but it does have a lifespan in mesh form. You can prolong its value, and help prevent off-flavors in your product, by cleaning it after every run. And, as soon as it doesn’t look clean—regardless how strict your sanitation protocols are—discard and replace it as necessary.
What are copper lines for?
Sales Director of copper capillary tube/ tin plating copper tube wechat: 18556881572 – Published Feb 4, 2020 Copper pipes are commonly used in the construction industry for water supply lines and refrigerant lines in HVAC (heating, cooling, and air-conditioning) systems.
Copper pipes can be manufactured as soft or rigid copper and offer excellent corrosion-resistance and reliable connections. The three most common types of copper pipe used in residential and commercial construction are Type K, Type L, and Type M. A fourth type, used for drain-waste-vent, or DWV, piping, can be found in some older homes.
Copper Pipe Sizing The actual outside diameter (OD) of rigid copper type is always 1/8 inch larger than the nominal size, or what the pipe is called. For example, a “1/2-inch” copper pipe has an outside diameter of 5/8 inch. It is true with all three common types of new pipe, K, L, and M.
- The inside diameter (ID) of copper pipe is determined by the wall thickness of the pipe, which varies by the pipe type.
- The internal or external fluid pressure may determine the type of copper piping specified for any application, the installation, the service conditions, and the local building code requirements.
Here Is a List of the Common Types of Copper Piping Type K Copper Pipe: Type K copper pipe has the thickest wall of all the common types. It is used for water distribution, fire protection, oil, HVAC, and many other applications in the construction industry.
- Type K pipe is available in a rigid and flexible form and can be used with flared and compression fittings.
- It is recommended for main water lines and underground installations because its thickness helps it withstand the pressure from backfilled earth in trenches.
- Type K pipe is not approved for use in natural gas applications because the gas environment can damage the joints of the pipes.
Type L Copper Pipe: Type L copper pipe is used for interior plumbing, fire protection, and some HVAC applications. It is available in rigid and flexible forms and can be used with sweat, compression, and flare fittings. Type L is considered the most common type of copper piping, as it can be used in many more applications than Type K.
Flexible Type L copper can be used to repair or replace old water lines, although rigid tubing is more durable. Type L also can be used outside the home where it will be directly exposed. Type L copper is thinner than Type K but thicker than type M. Type M Copper Pipe: Copper pipe type M wall is thinner than both type K and L copper.
Sold in both rigid and flexible forms, Type M is used most commonly for domestic water service and vacuum systems. It can be used with sweat, compression, and flare fittings. Type M tubing is favored for residential work for its relatively low price; a thinner wall means less copper and thus a lower price.
Type M copper is not allowed by plumbing codes in all areas and applications. Always check with the local building authority for restrictions on its use. Copper DWV Piping: Copper pipe for plumbing drains and vents was used in many old homes and has been all but replaced with PVC or ABS plastic pipe in modern construction.
It is suitable only for above-ground applications and has a low-pressure rating of 10 to 15 pounds per square inch (psi), much lower than the water pressure of most municipal water supply systems. DWV pipe usually has yellow markings to distinguish it from M type copper.
