Brewer’s Gold Rhizome
High-yielding sister to Bullion, ancestor to most major high alpha varieties.
Hop Qualities
Brewer’s Gold Rhizome Flavor
British bittering hop developed in 1919. Both Brewer's Gold and Bullion are seedlings of BB1 (found wild in Manitoba). Many modern high alpha hops were developed from Brewer's Gold. Has a resiny, spicy aroma/flavor with hints of black currant. (Reference)
Hop Growers of America Information
Brewer’s Gold is an English variety that is primarily used as a bittering hop. It is a descendent of Bullion and has many of the same varietal attributes. American-grown Brewer’s Gold has a higher percentage of alpha acids than its counterpart in England.

USDA Brewer’s Gold Rhizome Information
USDA ACCESSION NO.: 21082
SELECTION: From a cross made in the late 1960's or early 1970's at the Institute for Agricultural Research, Univ. Novi Sad, Yugoslavia; Hop Research Station Backi Petrovac; cross was probably made by Mr. Andrej Mijavec who was hop breeder at the time.
GENUS: Humulus
SPECIES: lupulus
CULTIVAR: Neoplanta
PEDIGREE: Northern Brewer (64107) x [male (SxS02)]
the male originated from the cross Savinski Golding (USDA
21049) x wild Yugoslavian hop
PRIMARY SITE: USDA Hop Cultivar Collection, OSU East Farm, Corvallis
ORIGIN: Seedling selection; USDA Accession No. assigned in 1974
DATE RECEIVED: 1974
METHOD RECEIVED: Rhizomes
AVAILABILITY: Commercial cultivar, no restrictions

MATURITY: Late
LEAF COLOR: Dark green
SEX: Female
DISEASES: Downy Mildew: intermediate to resistant
Verticillium wilt: unknown, probably tolerant
Viruses: unknown
VIGOR: Excellent to very good
YIELD: Very good
SIDEARM LENGTH: 20-30 inches
ALPHA ACIDS: 9.1% (10-year range 7.4-12.0%)
BETA ACIDS: 3.9% (10-year range 2.9-5.0%)
COHUMULONE: 36%
STORAGE STABILITY: Good (retained 63% of original alpha room temperature storage)
OIL: 1.28 ml/100 g; humulene 20%, H/C ratio 2.30; contains about 5% farnesene.
MAJOR TRAITS: High alpha acids and high yield potential; green stems (in contrast to the red stems of Dunav).
OTHER INFORMATION: Originally developed to replace the landrace Backa, a lower alpha noble aroma hop; thus far the variety has not been accepted by the world hop trade and acreage remains very limited. Sister of USDA 21081 (Dunav) and Vojvodina (USDA 21083).
Description
Brewer’s Gold is a high-yielding sister to Bullion that is highly susceptible to all hop diseases. It is an ancestor to most major high alpha varieties, with origins in 1919, and is grown mainly in southern Germany. Alpha acid content can fluctuate seasonally from environmental influences.
