Long time no drink a Kijoshu - surprisingly it is not very rich, which is easily drinkable. Quite rich sourness like yogurt and lactic acid - together with some rich sweetness. Again better to be paired with food :)
It is a Ishikawa style sake - rich in texture and more bitter in taste. I think it will be better pair with oily and meaty food, else it will be a little bit too much. The umami and minerals at the end will be a diverse one - depends on whether you like it or not.
