Chicago-based drinks company Sovereign Brands LLC has created what is says is the world's first alcoholic beverage distilled from soy. Called 3 Vodka, this super premium vodka took three years to develop by father and sons team Brian, Brett and Barry Barish.

However, a pending patent, has kept the manufacturing and distillation process a secret with only "soy isolates" being declared as a key ingredient; they are broken down into a liquid concentrate that that is combined with fermented grains to make the finished product.
