Dual Purpose, Aroma and Bittering

The hops prefers fresh environments and fertile and well-worked soils. It grows spontaneously on the banks of watercourses, along the hedges, at the edge of the woods, from the plains to an altitude of 1,200 meters if the climate is not too windy and humid. Its presence in nature is very common in northern Italy; wild hops are also present in all regions, including islands, although they become progressively more rare to the south.

It is cultivated for commercial purposes in both hemispheres, approximately between 30 ° and 52 ° latitude, and being very resistant to cold climates can withstand up to -30 ° Celsius.
