I opened a Kaya Iro for the comparison of drinking with Mashu.
The base is YAWARAKA Type 1. It has a little banana aroma. The acidity is less than the Mashu.
Polishing 49, firm taste and elegant fruit scent. As it's still freshly squeezed, there's a touch of spiciness typical of fresh sake, but it's also gentle.
I bought it at Takehara and Takehara Takeyoshiro Road and have been drinking it little by little. It has a solid taste, but it's fruity and not overpowering. It tastes good even if you put it to bed.
Glutinous rice 4-stage brewing, at room temperature.
This sake is brewed with glutinous rice in the fourth stage, and it has a strong sweetness (in the sense of glutinous rice, it is the same as Mirin). It has a faint sour taste, and the mouthfeel is a little dry, so the overall taste is not too sweet. In fact, it's better suited to the cold season.
