It may be foul to put it in a sake crocodile, but Jersey yogurt and Junmai Daiginjo sake. The classification is liqueur. It is sweet and sour and dobrok-like. Might be good for a dessert sake.
I ordered four bottles when I got home because I enjoyed drinking it served as a dobrok at a liquor store in Tsumago. This is the second bottle. It has 19% alcohol.
