At Tenka, 4/4th cup.
Personally, I liked this one the best out of the four cups.
It has a complex taste with a number of tastes mixed together, including the soft acidity of lactic acid, the umami of rice, and bitterness.
Among them, I especially felt a mineral taste, which is similar to the taste one gets when drinking hard water, and thought that this is the taste of nama-hashigashi-zukuri.
Because it is a nama-hara, it is also sweet and easy to drink.
I wonder if this is what is meant by mellow in sake.
It was a good learning experience for me.
I want to drink it again.
