The third cup was an all-Shizuoka sake, Eikun, a special junmai sake. Shizuoka rice, Honorifuji & Shizuoka yeast...and Mt. Fuji spring water. It is a sake with great flavor.
Initial impression is quite sweet (sake degree ±0). The umami of OMACHI is certain👍.
If it is to be used as an aperitif, it would be better to pair it with dark dishes. I don't think it is suitable as an aperitif, but it can be served alone after a meal.
