I've used vodka in the airlock for awhile now. Smirnoff for the airlock and Imperia for drinking.
In the rare case there is some small amount that makes it from the airlock into the beer, I'd rather have a little vodka with my beer instead of sanitizer in the beer.
I disagree with Kay Jewelers. I would bet on any given Friday or Saturday night more kisses begin with alcohol than Kay.
