Fünke Blue

A sibling of the ‘Freedom’ beers, this Blueberry Kettle Sour was made with a slightly different grain bill, but like it's siblings, had the addition of nonfat plain Greek yogurt to the kettle. The Lactobacillus strains in the yogurt eat some of the sugars and produces the lactic acid, which in turn imparts a tart character to the beer. This time we fermented the beer with our house ale yeast strain and added blueberry concentrate to the serving tank to give the beer a pinkish hue, and some sweetness to balance the acidity.
