It is said that this sake was stored at the site of a former coal mine.
I heard that there is a similar old sake in Yubari, so maybe it is popular in Hokkaido.
The price is not cheap.
I asked him to choose one after consulting with a sommelier at the liquor store section in the basement of the Shinjuku Keio Department Store.
The same preference.
I asked the liquor store for some Konami sake for my friends to drink at the Koenji Awa Odori festival and they recommended it to me.
It tasted just the way I liked it.
