Boysenberry Sour is the very first sour project that we put together for ourselves here at Hermitage, way back in July of 2012. The base beer was actually fermented in the wood, so the beer spent its entire life inside California wine barrels. After a long, slow aging process of about two years we added hundreds of pounds of Boysenberries to the barrels and let the fruit deliciousness meld with the delicate wine-like character of the beer. The end result is a complex-yet-drinkable, pleasantly tart, fruit-forward beer that develops on the palate with every sip. Sour beer the Hermit way.
