Grimm Gradient Sour

We’re calling this beer a Young Bruin – a new American sour style splintering off from the Oud Bruins of East Flanders. The base beer is a supple medium-bodied brown ale showing caramel, dried fruit, and rich malt. Combining spontaneous wild microbes with a farmhouse primary yeast strain, we achieve a mouthwatering acidity and complex fermentation character. Blackberries are added directly to the fermenter for raw tart fruit flavor.
