New Zealand’s Calicross emerged in the 1960’s and by-and-large disappeared by the 1980’s. Born out of a dire need for disease resistant varieties, Calicross was created as a cross between Fuggle and Late Cluster – the later being the crop decimated in the late 1940’s by Black Root Rot.
Developed by New Zealand’s then Department of Scientific and Industrial Research, Calicross changed the face of the New Zealand hops industry at the time and its commercial utilization remained strong for nearly 20 years. By 1980 however, its low growth rate made it a target for replacement by more vigorous varieties.
Useful for both aroma and bittering, it exhibits both earthy, fruity flavors and floral aromas closely matching those of Cluster.
