When I visited Akita, I bought this at a sake brewery. The acidity and umami spread in the mouth and gave it a refreshing taste. I drank it at home with mackerel with nanbanzuke and potato salad.
I drank this sake at the Akita Sake Kingdom Akita Sake-Navi, a store where brewers from 37 Akita breweries gather. It is called "Hiden Yamahai," but it is a pleasant sake with a good balance of umami and sweetness that spreads from the inside of the mouth to the throat.
At [Akita Sake Kingdom Akita Sake-Navi, a store where brewers from 37 Akita breweries gather] in Kawabata, Akita City, we compared three kinds of sake: Yamamoto: Junmai Ginjo Pure Black, Junmai Ginjo Wa-in, Junmai Ginjo Forest Green.
