The only vodka I've found that ISN'T vegan, was Vodka O organic vodka, which had whey in it.
And champagne should be vegan, whereas sparkling wine generally isn't.
Find a Brown Brothers sparkling wine and you should be fine.
Sorry to bring up an old thread... was searching to see if Bollinger was vegan and woot, it is!!!
But seriously whey in Vodka O?! Where do they come up with these ideas!
