At my usual udon shop. It is said to be a fantastic sake. I thought it was too good for me as a beginner, but I had it. I felt it had a good balance of aroma and taste. I guess it is a sake like sake. Anyway, it was delicious.
It is a liqueur, but it is made with sake, so I am posting it as an extra version.
The savory taste of Kaga-boucha tea matches the sake, making it a perfect food wine.
