Admiral is an excellent mid-season hop variety derived from Challenger and Northdown. Efforts to create Admiral began in England in 1984 at The College of St. Gregory and St. Martin at Wye, more commonly known as Wye College. The successful breeding program was led by prominent British hop researcher Dr. Peter Darby. It was released commercially to the brewing world in 1996 and was introduced as a potential high-alpha replacement or complimentary addition to Target hops.


It features higher acid content than either of its elders, possesses aggressive but smooth bittering qualities and boasts an orange-citrus and herbal resonance. This profile makes it a favorable choice for more bitter Pale Ales and ESBs. Taste it alongside East Kent Golding in Three Floyds BlackHeart English IPA.
