Sour beer brings a truly unique taste to your glass or bottle. You won't find the malty or hoppy flavors beer usually provides. Instead, you'll get tart and (duh) sourness. The signature taste comes from wild yeast, although the methods for incorporating it into the beer can vary wildly. In fact, the scope of flavors is just as broad as the brewing styles and types of sour beers. American Wild Ale, Berlinner Weisee, Gose, Flanders Red Ale, Lambic, Faro and Gueze are among the array of sour styles you'll find.
