Admiral is an excellent mid-season hops variety derived from grandparent Challenger and likely parent, Northdown. Its exact lineage is unclear. Hailing from Wye College, England it was released to the brewing world in 1998 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 making it perfect for more bitter Pale Ales and ESBs. Chapel Down employs Admiral almost exclusively in its Curious Porter due to its outstanding bittering abilities.
