Does ethanol go rotten in time like gasoline and produce varnish?
A. No. Alcohol is what preserves your wine and gets better as the years go by. But you need to start with triple distilled alcohol as made in the still I designed so that the fusil oils and other impurities are removed. But you must keep it sealed, as alcohol is hygroscopic–this means it will suck the moisture out of the air. So keep it capped so it doesn’t get diluted. Store it in glass, but plastic milk bottles are quite stable and the alcohol will keep OK.
