I am a chemistry nerd, and while I'm sure no one else really cares, the polyphenol is from the alcohol. Anything chemistry related that ends in "-ol" is a type of alcohol.Ah! It's been 6 years since I've been in a Chemistry class, but I feel as if I should have remembered this. Thanks for the info!
Just a note on cheap vodka vs. expensive vodka...Very informative, thank you! That's good to know.
I'm very pleased that so many people are finding this useful and so many people are giving more suggestions and helpful tips to those of us who need them! I can't say enough how awesome you all are!
