Our years of experience in artisanal organic miso-making make Miso Master Organic Traditional Red Miso one of the finest miso in the world. For centuries Japanese craftsmen have used natural fermentation to transform soybeans and grains into many types of miso, the rich, thick paste used for flavoring a wide variety of dishes. Though now almost extinct in Japan, these ancient practices have been in constant use since 1980 at the American Miso Company, the largest traditional miso works in the world. This traditional method results in superior quality miso. Fresh and unpasteurized, it has subtle, balanced flavors that only great care, high quality ingredients, and natural aging can produce.
Miso Master Organic Traditional Red Miso is our best-selling miso because it combines the health benefits of long-term aging with a sweeter, lighter taste than our other long-term varieties. It is aged naturally without temperature control for 12 months in our four-ton, hand-crafted Cypress, Redwood, or Fir barrels. The high soybean content in relation to the rice koji (grain inoculated with aspergillus spores) makes it necessary to age this variety through four full seasons because soybeans are more difficult to ferment, with their high protein and fat content, than the high-carbohydrate grains. This gives the aspergillus spores and lactobacillus bacteria sufficient time to completely break down the complex protein and fat molecules into their more digestible constituents.
Long-Term aged misos also have a higher salt content which retards the fermentation so that the process moves gradually. Miso Master Organic Traditional Red Miso has a complex flavor profile that is hearty, mellow, and mildly sweet. These long-term misos are the cask-aged Bordeaux Wines of miso. But the story does not end with just a rich taste, for these misos have their own special health benefits.
Soybeans are the main source of the potent phytoestrogens known as isoflavones which have been shown to effectively combat degenerative diseases such as cancer, heart disease, and osteoporosis. All isoflavones, however, are not created as equally potent antioxidants. The isoflavones found in soybeans and unfermented soybean products such as soymilk, tofu, soy supplement powders, soy flakes, and TVP are mainly isoflavone glucosides, which cannot be absorbed intact into the human bloodstream.
Only another isoflavone subgroup, the isoflavone aglycones -which include the famous anticancer powerhouses genistein and daidzein- can be absorbed intact into the human bloodstream. These isoflavone aglycones are found in meaningful concentrations only in fermented soybean foods such as miso, soy sauce (shoyu and tamari), tempeh, and natto. During fermentation as much as 90% of the isoflavone glucosides are converted into isoflavone aglycones. Long-Term Aged Misos also contain melanoidins, another powerful antioxidant group. These melanoidins are the pigments that give Long-Term Aged Misos their dark colors.
