Since I'm on a "bar" theme, I'd like to add the note of one who has never consumed alcohol, but made a living for a while as a bartender.
The predominance of Vodka only shows that most people consume cocktails, worldwide. While rarely does one hear an order of a mixed drink with WT101, most liquors are not consumed straight, especially vodka.
The young Beatles were told that classy people drank brandy. They hated it, so they had it with coke. I actually got to serve one to Ringo in the early 80's. Remy and coke.
Seriously, baby, I can GET a prescription for anything I want.
