MATURITY: late

LEAF COLOR: dark green

SEX: female

Viruses: free of major hop viruses when received.

VIGOR: very good

YIELD: very good

SIDE ARM LENGTH: 30 to 48 inches

ALPHA ACIDS: 7.4%

BETA ACIDS: 5.2%

COHUMULONE: 41%

STORAGE STABILITY: very good, retained 78% of its original alpha acids after 6 months at room temperature storage.

OIL: 1.77 ml/100 g. Humulene 9.6 %; caryophyllene 4.7 %; myrcene 58.5%; farnesene 4.2%; H/C ratio = 2.03

MAJOR TRAITS: high yield potential

OTHER INFORMATION: This is not a Hallertauer-type hop, oil and alpha are too high, the alpha/beta ratio is too high, cohumulone is similar to Cluster-type hops, and the H/C ratio is much too low. This hop also contains farnesene, while true Hallertauer has none.
