VIGOR: Very good

YIELD: Good to very good, 1500-1900 lbs/A

SIDE ARM LENGTH: 24-30 inches

ALPHA ACIDS: 8-9% in Germany, up to 11% in U.S. (5 yr. U.S. range: 7.9 to 12.9%)

BETA ACIDS: 4-5% in U.S., 8% in Germany (5 yr. U.S. range: 2.9 to 5.0%)

MAJOR TRAITS: Aroma hop considered by some to be comparable to Hallertauer mittelfrueh, moderately high alpha acids content, downy mildew resistant. Early maturity in Oregon (about Aug. 20).

OTHER INFORMATION: U.S. and Japanese breweries indicated that Perle is not a substitute for Hallertauer mittelfueher. Moderate acreage expansion in U.S. as a higher alpha/aroma hop for certain brewery blends. 1997 production: 792,400 lbs (about equally divided between Oregon and Washington)
