Columbus - Hopslist

The exact lineage of the proprietary hop Columbus is unknown. Its namesake was created in part as the result of a legal dispute between Hopunion and Yakima Chief when both parties attempted to patent the same hop. Yakima Chief’s variety was named Tomahawk®. After an agreement was reached, both names were registered. They are technically the same hop however.

Originally bred by Charles (Chuck) Zimmerman as part of a USDA breeding program sometime in the 1970’s, Columbus is sometimes referred to at CTZ (Columbus, Tomahawk® and Zues) though it is genetically distinct from Zues hops.

It features a punchy hoppiness and deep, pensive aroma with understated citrus notes—perfect as a dual use hop. Commonly used late in the boil and, when fresh, Columbus has a herbal flavor with a lemon citrus back note. Usable in a number of styles, notably American-style ales.
