Thunder Island Brewing Company: Vitamin K Kölsch

The grain bill of the classic copper-colored altbier — which is internationally also known as a German Brown Ale — is almost Munich-like, but with a slightly less “caramelly” character than a Märzen, and less dark than a dunkel. It differs from a Munich brew, however, in its much more pronounced hoppiness. This creates a wonderful blend of malt-and-hop aromas in the finish, which is often described as bitter-sweet. The uniqueness of this beer — an ale after all — comes from the clean fermentation of a relatively cold-tolerant, top-fermenting specialty yeast.

According to Goose Island's website, "With a light fruity aroma and a bright, crisp finish, Goose Island Summertime Kölsch is the perfect summer session ale. A Kölsch beer brewed in the traditional German fashion, you’ll find yourself enjoying and savoring each sip of Summertime as much as your do those hot summer days and cool summer nights."
