I would say xxx$ but its value is lost because "2nd-level registrant must have professional or academic qualification". Apparently its not enforced now but if someone buys this and the registry enforces it then they are screwed. An educational site about Vodka would not pay much for such a domain. low to mid xx$ at best is what I think the value of this is.
Don't think that if the domain in COM is sold for a big amount, the same word in other TLDs will cost much. The biggest producer of vodka already satisfied his requirements and doesn't need anything more. Others were not interested. I think that "vodka" domains don't cost anything.
