Columbus
The current Super High Alpha varieties, which include the names Columbus, Tomahawk and Zeus (CTZ) have the same female parent as Nugget, making them at least half sisters to Nugget. The CTZ varieties are currently used extensively for beer bittering. However, CTZ’s are losing favor due to their very poor storage characteristics and susceptibility to mildews.

Characteristics
Chinook was developed by the U.S.D.A. breeding program in Washington State and released in 1985 as a high alpha acids variety. This cultivar takes its name from a Native American tribe indigenous to the region around Washington state. The female parent is one of the English Goldings. The variety has a robust spicy, citrus aroma and grows vigorously in all areas.
