Made with natural yeast starter in Yamahai technique, it has a distinctively harmonious, deep flavor, making it the perfect accompaniment to meals enjoyed outdoors in nature.Established in 1830 with the motto of "quality first". Brewing sake is making rice. Not only do they focus on obtaining high quality sake rice, they dedicate time and effort in their labs to increase said rice's quality. Their efforts do not stop there however - in order to help sustain the environment, they implement the ISO14000 system of environmental sustainability, and also participate in various activities to preserve their natural surroundings. Additionally, they hold tea ceremonies, concerts, and cultural events for the local community. The goal is to make a fun, sustainable, and ultimately enjoyable environment with sake. A special Kubota seasonal release, "Seppou" can be served at all temperatures. Warming this sake releases all that Yamahai power and unleashes richer, rounder textures, whereas serving it cold increases the sharpness of its design.
