Re: [new_distillers] reflux still (copper for the tower)
The copper has two main purposes:
1. Provides lots of surface area for the alcohol vapor to condense on as it moves up the column. The condensation on the copper then drips back down the column, meets more hot alcohol vapor and re-heats and then re-vaporizes. What this does is essentially purify the alcohol vapor many times before it actually makes it to the top of the column. You can also use stainless steel scrubbers, ceramic rings called raischle rings, or marbles. The second reason is why you should use copper.
2. Copper reacts with chemicals in the alcohol vapor that contribute to off tastes in your final distilled product. It keeps the sulfer compounds (smell and taste bad) from getting into your final product. Stainless steel pot scrubbers are very popular for column packing but everyone that uses them comments how much better the finished product is once they change to copper.
Make sure the scrubbers are pure copper mesh. Copper plated steel scrubbers will corrode and make your distillate have an iron taste. Brawny brand copper scrubbers are best or pure copper mesh as sold by Amphora Society or Brewhaus is the way to go.
Note: Copper mesh is used primarily when you want to make a neutral, high purity product like vodka. If you want to make whiskey, many people run the still without the copper packing and it then works like a pot still. They usually distill the product twice to get the finished product. Using an unpacked column like a potstill retains the flavor of the grain, wheras using a packed column will remove the flavors as well as the impurities. All depends on what you are trying to make.
Hope this helps....
