飛良泉 マル飛 山废純米 はま矢酵母

Hiraizumi Maruhi Yamahai Junmai Hamaya Kobo is produced at Hiraizumi Honpo, one of Japan's oldest breweries founded in 1487 in Nikaho, Akita, using the brewery's proprietary Hamaya house yeast alongside the traditional yamahai fermentation method. The yamahai process naturally develops elevated lactic acid, giving this junmai a pronounced backbone of acidity, earthy depth, and robust umami that integrates beautifully when served warm.
