Testing alcohol content
With some of the recent concern about alcohol content, I am wondering if there is an easy way to test that.
I use Kombucha brewing in my microbiology classroom to demonstrate several concepts. But, if there is measurable alcohol, I could have a problem. I'd like to be able to just say it's tested and below 0.5%.
Grape juice you buy at the store will actually be ~0.5%
You can test the original and final gravity with a hydrometer to get abv%
