Made with Shiga's sake rice "Tamakae". Since we came all the way to the Kansai region. Served with chicken liver cooked at low temperature. The sake is not too rough for a sake with a 70% ratio. According to my research, a 4-pack bottle costs 1,400 yen. It's pretty cosy.

I think it's 5 million stone. Limited to restaurants.
There are surprisingly few sakes that have both sharpness and umami.
Kamizo is definitely one of them.
