USDA ACCESSION NO. : 19001
SELECTION: Seedling selection made in 1919 at Wye College, England
CULTIVAR: Brewer's Gold
PEDIGREE: Wild Manitoba BB1 x Open Pollinated (OP)
PRIMARY SITE: USDA World Hop Cultivar Collection, OSU East Farm
ORIGIN: Selected by E. S. Salmon at Wye College, England, in 1919. The mother plant BB1 was obtained in 1916 as a cutting from a wild hop growing at Morden, Manitoba. It was believed to have been a genuine wild North American hop.
DATE RECEIVED: Before 1950

COHUMULONE: 39 (10 year range: 36 - 45)
STORAGE STABILITY: Poor
OIL: 1.96 ml/100 g (10 year range: 1.38 to 3.42). Humulene 11.3% Caryophyllene 6.5%; myrcene 66.7%; no farnesene. H/C ratio = 1.73

OTHER INFORMATION:Identical to USDA 21116. This cultivar was a major hop variety, particularly in Oregon until it was discontinued from commercial production in 1985 after the advent of superalpha hops which had higher alpha-acids content and improved storage stability. Brewer's Gold is the ancestor of most major high-alpha hops grown around the world today (1997). It is still grown commercially in some parts of the world, notably Belgium and Spain.
