A famous female toji (brewer) was there, and we were able to talk with her. It's a very thick sake with a lot of body, but very drinkable. It seems like it would be good even if you let it sit.
It is a raw and unpasteurized sake with 13% alcohol content, made partly from white koji.
It has a refreshing, sweet and sour taste in the mouth and is easy to drink. It has a refreshing sweet and sour taste and is easy to drink.
Sweet and refreshing. This is the one that broke the image of traditional sake (old man's drink, alcoholic and difficult to drink).
The cup is Morozoff, which is a charm.
