After our barrel aged Blueberry Sour (for Fats Domino) was finished aging on 4# of blueberries per gallon we took the used blueberries and added them to a new beer and let the wild yeast ferment it out. The second use fruit still has an amazing amount of color and flavor left in it and it lets the underlying beer and wild yeast to shine. Bright and refreshing, this is a perfect summer thirst quencher.
