I used to like Monopolowa for being an authentic Polish potato vodka. It was cheap and has an interesting, subtle flavor.
I think Belvedere is probably the best of all (again, a traditional Polish vodka), though my vodka-tippling pal prefers Chopin, another Polish vodka.
I tried cake flavored vodka at one point. Yes, it is wedding-cake flavored right out of the bottle, has to be tried to be believed. Pinnacle or Three Olives brand, I can’t remember which anymore, but do Not waste your money on UV brand.
Then this curiosity, like a fly to the bug zapper, brought me to Stoli Blueberry. It’s nectar, folks. Actually too good- I got wasted because of Stoli Blueberry, maybe twice in too short a period, and my gf got pissed and dumped it down the sink. I could either take a stand for getting wasted or reform my ways.
So now I mostly drink LaCroix, and don’t drink vodka (or alcohol at all) much anymore. Don’t end up like me, draw the line at the cake flavor!
