SEX: Female

DISEASES: Downy Mildew: tolerant

Verticillium wilt: unknown, probably tolerant

Viruses: unknown

VIGOR: Good

YIELD: Good to very good (considerable year-to-year fluctuations)

SIDEARM LENGTH: 12-24 inches

ALPHA ACIDS: 10-12%

BETA ACIDS: 4-5%

COHUMULONE: 25%

STORAGE STABILITY: Fair to good (retained 50% of original alpha acids after 6 months room temperature storage)

OIL: 1.8-2.2 ml/100 g; ratio humulene/caryophyllene 1.90

Humulene 7.6%; caryophyllene 4.3%, myrcene 61.1%; farnesene 10.4%. H/C ratio = 1.96

MAJOR TRAITS: High alpha acids content

OTHER INFORMATION: This hop together with its sister selections Apolon (USDA 21051), Atlas (USDA 21052), and a related selection,Aurora, (USDA 21053) entered the hop trade in the 1970's as "Superstyrian" hops. The implication was that they be similar to Styrian (Fuggle-type) hops but higher in alpha acids content. In reality they are Brewer's Gold seedlings, and their quality characteristics are different from the true Styrian (USDA 21049, Savinski Golding). This has caused considerable confusion in the world hop trade. In recent years the acreage of Superstyrians has been reduced in favor of the old established Savinski (Styrian) Golding (21049). The acreage of Ahil in Slovenia has remained very limited.
