Eastern Gold

Eastern Gold is a Super Alpha variety developed in Japan by Kirin Brewing Co. Ltd Hops Research from Kirin No. 2 and OB79, an open-pollinated wild American hop. Despite its yield potential, high alpha acids and storage stability, it seems it is not currently being grown in any significant commercial capacity.

Very little is known about the history of its use and its flavor profile but it was originally bred in a similar vein to Toyomidori and Kitamidori as an effort to replace Kirin No. 2 with a similar, yet higher-alpha variety.
