Horizon is an excellent bittering hop, not only for its high alpha percentage, but also low cohumulone content, which ensures a very smooth bitterness. Horizon is a dual purpose variety and the aromatic qualities are not to be overlooked. It has a very desirable, delicate nose with floral and citrus notes. Horizon hops are the half-sister of Nugget that features the lowest cohumulone level of any hop. Horizon hops are commercially grown in small quantities and are quickly gaining popularity in the craft brew industry. Horizon was developed in Oregon in 1970.
