I finally tried a sake store, which I had been trying to get into for a long time because of the high hurdles,
I finally found the sake that I had always wanted to drink, Tobiran.
Delicious!
A 30 year old (Heisei 6!) unearthed from my parents' house. Echino Umezato. Old sake at room temperature...?
Surprisingly, it was not only drinkable but also delicious.
At a tasting at the Agricultural University store,
It is nigori, but it is recommended as good for warmed sake.
It is indeed delicious even when heated. It is also delicious cold!
