STABILITY OF ESSENTIAL OIL OF HOPS [PDF]

Journal of the Institute of Brewing, 1976
The stability of hop essential oil in beers, in hops and in aqueous emulsions has been investigated. Hop character of beers treated with hop oil emulsion has stability on pasteurization and storage similar to that of dry hopped beers. When bottled with high levels of headspace air, beers lose hop character.
