Repeated distillation of vodka in compliance with proper techniques removes third-party impurities, improving the quality. People the final product is called a “double brew”. Will have to spend 2-3 hours longer, but the end result is crystal clear, soft distillate odorless.
The secondary stage lends itself to any brew, regardless of raw material. Recipe of Braga and selected the technology of distillation (moonshine) do not change. To Refine you can even drink, kicked much earlier.
The technology of obtaining of double moonshine
1. The dilution with water. Before the double distillation measure the fortress, determine the amount of pure alcohol, for example in 1 liter of 40% contains 400 ml of pure alcohol (this is necessary for the selection of fractions in the third stage), then the brew is diluted with cool water to 20%. To distill a stronger liquid is dangerous, since high concentrations of alcohol vapors can lead to fire moonshine. In addition, strong brew a very strong molecular bond with fusel oils, in consequence of which repeated distillation did not produce the expected effect.
2. Cleaning. Sugar and cereal brew (in some cases) further purified charcoal, potassium permanganate or other method. Fruit distillates are usually not clean, so there was a slight aroma of raw materials.
If you select potassium permanganate, a three-liter jar of moonshine 40% mix 3 grams powder in 300 ml of hot water, pour the solution into the brew, stir well and allow to stand for 15-20 minutes. Then add a tablespoon of salt and baking soda. After 2 hours, strain the mixture through a cotton-gauze filter.
3. Distillation. Does not differ from the first distillation, but it is very important to split the output into two fractions: “heads”, “tails” and “body”. The first 8-12% yield from the amount of pure alcohol (identified in the first stage) to not drink, it is harmful faction called “heads”, it has an unpleasant smell.
The next 80% is a double brew, which we need. It is harvested until the fortress in the jet falls to 45-40%. The last faction – the “tails” can be used to improve the next fortress of Braga, to drive to a distillation column (to be pure alcohol) or just pour out.
Fraction after distillation
After the second distillation turns the brew 60-70% not requiring additional treatment. It remains only to dilute it to drinking strength (40-45%).
