Oude Tart is a Flemish-Style Red Ale aged in red wine barrels for up to 18 months. This version has had boysenberries added for the final stages of barrel-aging. In fact, there are over two gallons of boysenberry purée per barrel. The final compilation is pleasantly sour with hints of leather, dark fruit, tart boysenberries and toasty oak. While the Flemish-style red ale is one of the more classic beer styles that we make, it’s not a style that you can find too often in the United States. Originating in style from the Flanders region of Belgium, near the French border, this dark, sour ale has roots deep in brewing history and predates most of the ales that have become popular in contemporary culture. We’re doing our best to keep the tradition alive by brewing and aging this beer here on the west coast.
