Nov 5, 2018 at 18:58 comment added pkofod It might be a bit of a weird question, but say I'm fermenting something using bacteria or yeast on the skin or in the fruit/root (ginger)/cabbage. I know we're moving beyond brewing with the cabbage, but it's related to my question quite closely. How do you know that the fermentation is indeed producing ethanol and it is not homolactic fermentation? The question came into my head as I was gathering information on ginger ale/ginger beer production. Information was very different from different sources, so I wondered if you could directly measure alc % determine the role of yeast.
Nov 5, 2018 at 17:55 comment added Flydog57 I'm curious why you don't want an indirect measurement, and insist on a direct measurement. If you have access to a chemistry lap, you could, for example, use mass spectrometry. Just about every other measurement will be the result of deducing alcohol content through some physical characteristic of the mixture.
