Black Cow Vodka is pure milk vodka, produced in Dorset, England, from the milk of grass-fed cows, the company says.

It is distilled from the whey of milk and treated to a proprietary blending process created by dairy farmer Jason Barber, whose “inspiration came from a desire to diversify the product of his 250-head dairy herd and his personal interest in vodka,” the company says.

Black Cow Vodka is now available in the US for a suggested retail price of $39.99 for a 750ml bottle.
