Biere Royale, modeled after the french cocktail Kir Royale, is a sour ale with black currants. First brewed as a popular draft-only beer for the Portland Fruit Beer Festival, the bottle conditioned version has a bright acidity from a house-grown Lactobacillus culture originally harvested from yogurt. Black Currants are added during primary fermentation to add additional acidity, fruitiness and a deep purple color to the final product. The process was catalogued very well by our friend Sanjay at The Not So Professional Beer Blog.
