Our high quality unpasteurised brown rice miso, a fermented Japanese soya paste, is carefully made to an old family recipe and traditionally aged. During the 18 years Clearspring's founder Christopher Dawson lived in Japan he became an expert on miso quality, and the Clearspring range is his selection of the finest traditionally made Japanese miso. All traditionally fermented Japanese miso is prepared by cooking the finest organically grown ingredients (whole soya beans and cereal grains) and combining them with a koji culture (grains or soya beans inoculated with Aspergillus oryzae mould spores) sea salt and water. Then naturally aged in cedarwood kegs over many months at ambient temperature the enzymes from the koji, along with naturally occurring yeasts and bacteria, gradually break down the complex grains and beans into readily digestible amino acids, fatty acids and simple sugars. The resulting miso has rich and complex flavours and an abundance of umami, the fifth taste.
