37525Re: [Distillers] What proof is preservative?
- Nov 2, 2006Hi Richard,
you'll need much higher %ages and preferably acidic. As an analogy,
think how easy beer turns to vinegar, and how much more difficult it is
to have 12% wine go off (it still does though). Alcohol as a sterilant
swab is usually ca 50% (higher is actually less effective, for reasons
I won't go into).
I suppose you are thinking of storing largish quantities, otherwise
distillation (or even boiling - preferably 2 times with 3 days between
to kill spores) would be good.
