Dewasansan rice is named after a mountain range in Yamagata prefecture for which it was designed to thrive. Officially recognized in 1997, Dewasansan is highly prized as a junmai ginjo rice, giving the sake a smooth, soft and deep flavor. To use Dewasansan rice, Yamagata prefecture requires all aspects of the sake be made with Yamagata products. It then undergoes a tasting board review to ensure that it meets the expectations of quality.
