Columbus is sometimes referred to at CTZ (Columbus, Tomahawk and Zeus) though it is genetically distinct from Zeus 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. When fresh, Columbus has a herbal flavor with a lemon citrus back note. Usable in a number of styles, notably American-style ales.
