It's totally different from Dewa Tsanzan. The difference in yeast is huge.
It's a little bitter, but maybe that's because it's been so long.
I like Gohyakumangoku, but I prefer Hayashi.

It has a little bit of a corner of alcohol taste, but the acidity, umami, and aroma are well balanced in all areas, and it gives you a nice fluffy feeling when you drink it ^ ^ ^.
