Two-Year Aged Shinshu Miso for Miso Soup and Everyday Cooking
Made by Maruman in southern Nagano Prefecture, this Shinshu miso is slowly aged for two years at low temperatures, allowing it to develop a deep, complex umami and rich aroma. A blend of three types of koji, made from rice, barley, and soybeans, contributes to its distinctive flavor. With a robust, savory character and a pleasantly coarse texture, this red-toned miso is especially delicious in hearty miso soup, stews, and yaki-onigiri (grilled rice balls).
Made with 100% Japanese ingredients—soybeans, rice, barley, and salt—this miso contains no added alcohol or preservatives and is left unpasteurized to preserve its naturally occurring yeast. Its rich flavor also makes it a wonderful addition to your everyday miso soup when you want a little extra depth.
Maruman – Pioneers of Additive-Free Miso Since 1888
Founded in 1888 in Iida, southern Nagano Prefecture, Maruman has been making miso for generations, combining traditional fermentation techniques with innovations in miso production.
The company’s fourth-generation president, Kyoichi Nakata, pioneered a method of producing additive-free, unpasteurized miso (nama miso) while maintaining its quality and stability. Rather than keeping this patented technology exclusively for Maruman, he shared it with other producers, contributing to the wider availability of naturally fermented miso in Japan.
Today, Maruman continues this commitment to quality miso making. Its Two-Year Aged Shinshu Miso, known in Japan as Kyukyoku no Ippin (究極の逸品), meaning “The Ultimate Masterpiece,” is one of the producer’s most beloved varieties, with the highest repeat-purchase rate among its miso products.
