This authentic sweet potato shochu is made using the new and rare variety of sweet potato, "Suio." "Suio" can be eaten stem and leaf and is packed with essential nutrients such as iron, calcium, carotene, dietary fiber, and polyphenols. It is also said to suppress the accumulation of fat in the liver and prevent blood sugar levels from rising. For this rare new variety of sweet potato, black koji is used, and 100% domestic rice is used for the koji rice. The water used for dilution to adjust the flavor from the original alcohol is the local Shimanto spring water, "Inoriyama no Mizu" (ultra-soft, natural water), resulting in a unique richness and depth of flavor. The label and production are overseen by Takeshi Koike, who sold the shochu "Dorokame" in 30 countries worldwide, with 540,000 bottles sold. Volume: 180ml
