Origin and Description

Calicross has come and gone as a hops variety. The story goes that Black Root Rot was cause for major crop loss in New Zealand, namely to the Californian (Late Cluster) variety. In 1949 a new program was setup to work on more disease resistant varieties. Fuggle Hops was crossed with California Cluster to produce Calicross. This was the year of 1960, and it helped to transform a new generation of hops production in New Zealand. Calicross was grown until the early 1980's when it was replaced with more vigorous varieties.

Calicross hops is/was a dual use variety with an alpha acid content of 5.8%-7.9%, great for all kinds of beers. It carries a high co-humulone content at 36.0%-44.0%. It is another New Zealand variety with high myrcene oil content. It also has uniquely low caryophyllene levels. Calicross is compared to Cluster with a floral flavor and aroma.
