This sake is carefully brewed with 100% Yumenokaori, sake-brewing rice from Aizu and the underground water drawn from 100 meters below in Kitakata. After pressing, it is immediately bottled and undergoes 20 days of fresh storage without pasteurization, allowing the glucose concentration to increase. It is then subjected to a single pasteurization process and kept under -5℃ refrigeration.

The sake has a soft and gentle mouthfeel, with a subtle yet refreshing sweetness, and a well-defined umami flavour that emerges afterward. Despite being medium-dry, it retains a mild and pleasant sweetness.
