Take my word, speaking as a "problem drinker" who throws down vodka on a nearly daily basis and has drank everything from Grey Goose to the cheapest of the cheap (Nikoli, Bartons, McCormick, Hawkeye).....as long as you have the right "flavor" you like to mix with it (for me, it's mixed with lemonade and strawberry/watermelon MIO), it totally doesn't matter what the vodka is.....preferably the cheaper the better. And why anyone would ever do vodka straight, I'll never understand.
I'm quite content with buying a 1.75 jug of cheap stuff for $9.99 at the local Fareway, than spend $24 on a fifth, even being Cyclone Vodka....UNLESS you tell me how much percentage of the proceeds are going to ISU. Just telling me that "a portion of the proceeds" just doesn't work. It could be 1/2 of 1%. I'd rather just donate directly to the athletic program.
But, I guarantee you that I will have a bottle of Cyclone Vodka in my house. I might buy it, or maybe one of my friends will bring it as a gift, either way, it'll help the "percentage of the proceeds". THEN, after we drink it, I'll continue to utilize the bottle, by refilling it with the cheap stuff which does the same job, but for a whole helluva lot less.
P.S. For about every other alcohol, quality makes a difference, but with vodka, no.
