Double Distillation

Double distillation of you neutral spirit is the most important method you can use to improve the quality and quantity of your finished alcohol.

​1. Distil your wash as normal, you do not have to discard anything as you will do it on the second distillation anyway. This is called a "stripping" run because you "strip" the alcohol.
2. Collect the spirit and dilute to 45% using the calculator found here
3. For every 8-10L spirit add 1 tablespoon of sodium carbonate (not bicarbonate).  This is sold as washing soda at the supermarket.
4. Run the still as normal, discarding the first 50-100mLs. This is called the "spirit run"
5. Dilute to 40% and carbon filter

To save time you can strip the alcohol from two or three ferments and then do a single spirit run.
