There are no short cuts in brewing g. The rice used comes from one of the finest rice growing regions in the world, the Sacramento Valley. The climate, soil and water resources are ideal for growing rice and the trek north to Oregon is relatively short. Koji-kin and yeast strains used in g saké are both from Japan and combined provide the diversity of flavors layered in each bottle. And the water? Its from our home here in Oregon. Perfect for saké.
