It has a very strong acidity and umami flavor typical of Furoisen. The acidity is better balanced at room temperature. The acidity disappears when it is warmed up. Is there a difference in the type of acidity?
Room temperature is recommended! The balance of rice flavor and acidity is good, and the rich taste can be enjoyed. If you heat it up, the acidity will be too assertive and you will feel the alcohol taste, so it is best to keep it at room temperature or lukewarm.
Recommended to be warmed to lukewarm! It has a traditional sake taste with a strong umami flavor, but it has a mild acidity that makes it easy to drink. When warmed, the acidity becomes more pronounced, but it is not harsh and is still easy to drink.
Recommended for people who don't like alcohol! Not as persistent sweetness as expected, easy to drink with tartness of mandarin oranges. It also has a slightly effervescent taste.
