Additives are never used nor alcohol added to produce awamori; only rice, water, yeast, and black koji culture, all of the highest quality,are used. Kumejima’s Kumesen uses clear water from pure Doga spring for particularly tasteful awamori. Careful manufacturing techniques of Kumejima’s Kumesen are also responsible for producing the nice-tasting awamori. To take advantage of the live ingredients such as yeast and black koji culture, underground spring water and a natural breeze, instead of refrigeration, are used to cool the mash. The mash is stirred gently by hand.Kumejima’s Kumesen employs optimal methods to keep the savor of the ingredients. The mash is heated indirectly and distilled at normal pressure using a single pot still. This is unique to Okinawa and developed through long experience.The distillation produces mellow liquor. It becomes mellower with maturation. Until its shipment, Kumejima’s Kumesen brand awamori sleeps soundly in tanks or earthenware pots to enhance its appeal even further.
