Vodka for base in extracts???! May I ask what "quality of vodka"? I'll admit to being a serious light weight with alcohol but, I'll just as easily admit to being an alcohol snob just the same. After all, if I'm gonna taste something it's not gonna be crap. My annual consumption can be calculated in the 6-pack per year category. And has been that way for, well... At least 40+ years of my life.... There were a few years where that avg. was breeched, 2 of them birthdays & once while in the Navy after graduating Rescue swimmer school.
You would be a drunken Souse compared to me.
I get that strange look when I am asked by medical people about my alcohol consumption. I am sure they think I am lying as people are either teatotalers or drinkers.
My reply is always “ I suppose a drink every couple months”.
