Originally selected by Charles Zimmerman for Hopunion, Inc., Columbus is a descendant of Nugget. It is a high alpha variety and is primarily used for bittering purposes. Columbus is often referred to as CTZ, a trio of similar hops including Tomahawk® and Zeus.
Columbus features a punchy hoppiness with a deep engaging aroma and understated citrus character.
It can be used at the beginning of the boil for bittering and as a late addition and dry hop for flavour and aroma.
