Sold by weight at Okinaya in Kyoto. Sake-like aroma, fresh but not light, sourness and umami.
The following is from the brewer.
Rice that can take advantage of the softness of the brewing water is used. Gently and carefully brewed. It has a gentle mouthfeel and a calm aroma.
Bottled straight from the tank, no heat treatment. Keep in a refrigerator for at least 3 days after opening. Drink as soon as possible, either cold or on the rocks.
Since I went to Fukushima, I also stopped by the Nieda Honke to buy some. I had a paid tasting, but this was the one I was after from the beginning. It has a rich, sour and dark taste, something that Setogawa-san used to spice up and pair with sweets.
