Sour ales encompass a wide range of tart and acidic beers that are intentionally fermented with wild yeast strains or bacteria. They can vary in flavor from mildly tangy to intensely sour, with fruity, funky, or vinous characteristics. Sour ales may be aged in oak barrels to develop additional complexity and are prized for their refreshing and palate-cleansing qualities.
