Carolina Beer Co. Cottonwood Frostbite

Also known as Carolina Beer Co. Cottonwood High Gravity Frostbite
Commercial description
From the breweries of Colorado and the Pacific Northwest comes the winter tradition of a hearty brown ale that finishes with a strong hoppy taste. Made with a blend of Crystal Malts, and balanced with Centennial and Columbus hops, the frostbite was aggressively brewed to warm the beer drinkers in the southern Appalachian Mountains. Even if it’s not cold where you are, you will certainly enjoy this distinctively bold ale. After the change in NC ABV laws, this beer was reformulated as High Gravity Frostbite.
