Sorachi Ace

Japan

AROMA PROFILE

Sorachi Ace was developed in 1984 for Sapporo Breweries Ltd. From (Brewer’s Gold and Saazer-OP) x Beikei No. 2 (as a male) and is named after Sorachi, a subprefecture in Hokkaido. The aroma variety produces a good yield and is particularly resistant to powdery mildew, wilt and botrytis with a relatively high Alpha Acid content (12-16%) and also a high oil content (2-3 ml/100g). The original breeding objective was to develop a variety that was very similar to Saaz, but had a higher alpha content. Today, Sorachi Ace is grown only in the USA
