About

Part of the CTZ (Columbus/Tomahawk/Zeus) group of similar proprietary varieties, Columbus has very high alpha acids that make it one of the most efficient US bittering hops. It carries a pungent, dank, earthy and slightly spicy black-pepper-and-licorice character with subtle citrus that survives into late additions, and is a workhorse base in American commercial brewing.
