Copper is the preferred material in the construction of a still to impart flavor into the distilled spirits. 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.
Is copper necessary for distillation?
There is a good reason to use copper for distilling. Copper catalyzes (allows to occur) certain reactions that remove undesirable notes/flavors in the distillate and make it ‘smoother’. Without copper, the distillate will smell and taste sharp and unpleasant. However, the still doesn’t need to be made of copper.
How does copper affect distillation?
During distillation in cop- per pot stills, the copper acts to reduce sulphury aromas in the resultant spirit by reducing the levels of sulphur compounds such as dimethyl trisulphide (DMTS). This work has shown that the copper is more effective in this role in some parts of the pot stills than others.
Why is copper used for distilling alcohol?
Think of copper as a ‘silent contributor’ to spirit quality; the availability of clean copper inside the still is vital to allow complex chemical reactions to take place, removing highly volatile sulphur compounds – chief among them dimethyl trisulphide or DMTS – and helping in the formation of esters, which tend to Jun 21, 2016.
Do you have to use copper for a moonshine still?
As I mentioned above, copper is a vital component when you’re distilling spirits. However, your entire still doesn’t have to be made out of copper in order to get the sulfur-eliminating benefits. You can go with a stainless steel still and also use copper in your column packing.
How does a copper still work?
It is effectively a giant copper kettle within which a low-strength alcoholic liquor – such as a beer or wine – is heated. The alcoholic compounds evaporate at a lower temperature than water and thus turn into a gas, separating them out from the non-alcoholic compounds.
What type of copper is used for still?
Do you need some copper pipe to build your still column? This is the pipe you need. This is type L copper pipe. We also have copper ferrules that you can solder onto the end of this pipe to build your distilling column.
How long does a copper still last?
These unwanted and flavor-changing sulfur compounds are chemically removed from the final product resulting in a smoother, better-tasting drink. All copper stills will require repairs about every eight years due to the precipitation of copper-sulfur compounds.
How do you make a still at home?
How to Make a Still at Home Supplies for Making a DIY Still. Step 1: Drill a 1/8-inch Hole on the Aluminum Pot. Step 2: Wrap the Thermometer with Teflon Tape. Step 3: Place the Thermometer in the Hole. Step 4: Secure the Thermometer with Hot Glue. Step 5: Drill a 3/8-inch hole in the Pot Lid. Step 6: File as Needed.
Why do stills have coils?
Each coil increases the surface area of water cooled copper to create more condensation. You might have noticed the reflux column the condenser, product cooler and even the column packing all constructed from copper. The main reason is copper acts as a catalytic to reduce some unwanted compounds like sulfur.
How are whiskey stills made?
Each time a whiskey is heated, condensed, and collected, we call that a distillation. The resulting distillate is called a “low wine,” and is diverted and distilled again in a “spirit still” to increase the alcoholic strength as well as build more flavor.
Can you put fruit in a thump keg?
You can choose to add fruit peel, herbs, spices, and mashed ripe fruit directly into your thumper keg. Just remember that in the case of mashed fruit, you will need to add large quantities to impart that flavor.
Do you put water in a thump keg?
Depending on your thumper, it’s typical to plan to fill it about halfway with liquid. This is the case for our Brewhaus thumpers, but if you are using a different thumper, check with the manufacturer or adjust the fill level as you see fit.
How thick should copper be for a still?
1/4 ” copper tubing – 8 ft should do.
Why is it called a still?
A still is a tool used to clean a liquid. Stills get their name from the word distillation. Distillation is the process of boiling and cooling a liquid to purify it. Stills are most often used to create alcohol, but they can also be used with any liquid.
How does a still make alcohol?
In a nutshell, wash is heated up in a still to a temperature above 172 degrees, but below 212 degrees. Ethanol starts to boil and turns into a vapor, separating from the wash water. The vapor is then condensed (turned back into a liquid) and drips out of the still into a mason jar or some other collection vessel.
Who made the first still?
Although the exact origin of stills and distillation remains unknown, Saracena alchemists who conducted some of the first scientific studies on distillation during the middle ages attribute the invention of the Alembic still and its use for purifying alcohol to Muslim alchemists in the 9th century.
What is copper tubing used for?
Copper tubing is most often used for heating systems and as a refrigerant line in HVAC systems. Copper tubing is slowly being replaced by PEX tubing in hot and cold water applications. There are two basic types of copper tubing, soft copper and rigid copper.
