Columbus US 47 Hops are often referred to as CTZ, a trio of similar hops including Tomahawk ® and Zeus.  Columbus is a half sister to Nugget and is a super high alpha variety.

Columbus is used as a bittering hop with an intense, pungent aroma and has a high resistance to mildew and other disease.

Columbus 47 Hops make a great dual purpose hop in your beer. Columbus brings both a bitterness kick to the table as well as strong dreamy aroma. Columbus brings a 13%-16% alpha acid rating to the table, making it ideal for laying the bitter foundation for beers such as Pale Ales, India Pale Ales, Stouts, and anything Imperial. In the same capacity Columbus is commonly used for late-boil or dry hopping for its herbal, earthy character. The aroma is pleasing and citrus notes may be found in fresh batches.

The oil content within Columbus Hops is moderate, and the essential oils are relatively balanced. It is a moderate yielding plant edging towards the higher side, and is grown widely in the U.S. This variety produces medium to large compact cones, and the lupulin is on the paler side of yellow. Some of the most forward looking breweries in the U.S. are using Columbus to flavor their American Style Ales.

The exact lineage of the proprietary hop Columbus is unknown. Its namesake was created in part as the result of a legal dispute between Hop Union 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.

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 Zeus) though it is genetically distinct from Zeus hops.

General Trade Perception

Solid Bittering Hop.  Excellent for dry hopping.  Some brewers may pick up Onion Garlic in early use and brewing but that will dissipate over time. Columbus provides a solid base note upon which to build strong hop forward American style ales.  Widely grown and a standout grower in Idaho Columbus has gained a lot traction of late in modern US IPA style use.
