For 120 years, Marusho Jozo has been using traditional manufacturing methods to hand make their products. They select high-quality local soybeans, rice, and natural spring water, then by using the brewery's unique old-fashioned manufacturing method and natural microorganisms, they carefully age their miso for two years. This all-purpose Shinshu miso is characterized by a faint acidity, a fully-aged, rich umami, and a balanced timeless taste.
