I got it from Kazu!
I heard that you have to freeze half of it to drink it, but it was a little cold because of the time it took, but it was a little bit like Hineka.
It is softer and mellower than normal Fukuji.
Is it because it has been laid down for a year? For a moment there seems to be an old-fashioned flavor, but this is probably due to the unique flavor that has matured deep underground.
