Cowdery - Have you tried it? I've not, so I can't comment on the product itself, but putting myself in the consumer seat, I feel pandered to, and I don't like the message. For all I know its no different than a "whiskey" vodka, and not all that different than, say, "Whipped Cream Vodka"?
I wonder if TTB would allow a "WHISKEY FLAVORED VODKA"? Not that I want to make that, sell it, or even drink it, but, if you can have a "JUNIPER FLAVORED VODKA", rather than "GIN," then why not let the market decide.
