Black Cow Vodka.
Black Cow Vodka was created by Jason Barber and Paul Archard, through a trial and error process that took approximately five years. Barber had been inspired by the drink Araka, an alcoholic form of fermented mare's milk used by Genghis Khan and his armies. Araka, which is still made today, is approximately 7% ABV and more akin to a beer. 
The vodka is made using whey, as it is high in lactose and sugars to convert to alcohol with a specific yeast that will react with lactose. The product is triple filtered, including through a carbon made from coconut husk. After distillation, the product comes out at 48% ABV, at which point they process the liquid into Black Cow Vodka. The final concentration of the product is 40% ABV. In total, of milk are required to make of vodka.
The curds from the same milk are used to make "1833 cheddar" and "Black Cow Deluxe Cheddar", two other products from the same dairy farm, meaning that there is very little waste between the two processes. In 2016, the company produced 120,000 bottles of the vodka.
