Created in 1985 by Hop Products Australia in the Rostrevor Breeding Garden in Victoria, Topaz was always intended to be a high-alpha hop. The result of a mix between an Australian high-alpha variety and a UK male sourced from Wye College in England, Topaz is a unique blend of Australian and European flavors and aromas.
Aroma: Australian Topaz Hops have a rich and intense aroma of fleshy citrus and apricot, with a "dank" overtone. Very similar to Amarillo, Apollo, Columbus and Summit but with a softer citrus edge.
Possible substitutions include Galaxy, Citra®, Cascade, Riwaka, Rakau, Amarillo®, Apollo, Columbus and Summit
