A Vodka made from cow's milk?  Yes, it's a reality, a guy in England makes it and apparently people really love it.  Here's what their website says:

Black Cow is the world’s first pure milk vodka, made entirely from the milk of grass grazed cows and nothing else. Fresh whole milk makes an exceptionally smooth vodka with a unique creamy character.

Jason Barber is a Dairy Farmer with 250 head and he got the idea from a documentary on how Siberian's make vodka from Yak's milk.   So HOW is it made you ask?  Here's another description from their website:

The milk is separated into curds and whey. The curds are used to make cheese, the whey is fermented into a beer using a special yeast that converts the milk sugar into alcohol. This milk beer is then distilled and treated to our secret blending process. The vodka is then triple filtered and finished, before being hand bottled.

Apparently 007 actor Daniel Craig and Elizabeth Hurley love it and it's critically acclaimed by so-called "experts".  Is this something you would actually drink?  Maybe there's a new market here for dairy farmers that we may have never thought of before.
