Ah, this is Yamagata sake. It has a smoky aroma like straw. It is neither sweet nor spicy, but has a wide range of umami dimensions. A deep granary. Sake is interesting because you can encounter this kind of individuality.
It is said to have been created to accompany seafood, since sushi was called "yasuke" in the Hanayagi world. It has a mellow, full flavor, yet it is refreshing and easy to drink. My favorite type.
A bottle purchased for New Year's Day and not opened until April 12, when the groundbreaking ceremony was celebrated. The sweetness and umami spread clearly. The effort of the brewery is evident in this bottle of Kaiun.
