"Sakamoto Kurozu" fermented and aged for over a year is blended with black-jiuqu sweet potato shochu. The flavor and aroma peculiar to black vinegar are retained, but the richness and sharpness of the sweet potato shochu are tailored to create a refreshing taste. You can enjoy it widely as an aperitif, or as a drink before going to bed. This is the perfect drink for those who love alcohol but are also concerned about their health!
