Shinshuwase

Grown exclusively in Japan, Shinshuwase is a high yielding aroma hop. It dates back to the early 1900’s, possibly earlier. While it still exists, it has largely been replaced by Kirin No. 2, Toyomidori, Kitamidori and Eastern Gold as a commercial crop.

A cross between Saaz and open pollinated White Vine, Shinshuwase was originally used as a bittering hop, but after the introduction of super alpha varieties, it is now considered far more useful as an aroma hop. Shiga Kogen Beer currently uses it in that capacity for their Draft Pale Ale and Miyama Blonde and describes its aroma as lemon-centric.
