SUIO is made from sake made with local Gifu-grown sake rice "Hidaminori," which is poured into enamel tanks lined up in the back of a dimly lit storehouse and aged. The sake, aged in a dark and air-shielded warehouse, has a variety of colors, from transparent to honey-colored, and is now beautiful amber. The theme is "perfection of imperfection." Sake matures with age. The endless journey of maturation is a journey without completion. With this in mind, the symbolic motifs are a "triangle," which represents regeneration and repeated growth, and a "circle with one missing side," which represents imperfect perfection, and the seal is a "shide" (paper streamer) (used in Shinto, a spiritual culture of Japan) that represents a barrier. Package design (right side of photo)/The bottle box is made of a cylindrical paper tube. The surface of the lid is embossed with a concentric pattern of tree rings from the center of the front, expressing the aging period of the sake. In addition, the top and bottom of the paper tube are decorated with wooden caps made from recycled Hida cypress wood, making it an environmentally friendly product.
