Red Miso

Red miso is a fermented soybean paste originating from Japan. It is made by fermenting soybeans with salt and koji (a mold culture), often with the addition of barley or rice, and is aged for a longer period than other miso types, giving it a darker color and richer flavor.

Red miso is used as a flavoring agent to add a savory, umami depth to foods. Its robust taste makes it suitable for marinades, sauces, dressings, and hearty soups, particularly in Asian-inspired dishes.

Red miso is generally recognized as safe (GRAS) by the FDA when used as a food ingredient. Fermented foods like miso contain probiotics, which may support gut health. Regulatory bodies like EFSA have evaluated fermented soybean products. Evidence on the health effects of miso consumption at typical dietary levels is mixed, with some studies suggesting potential benefits for cardiovascular health and others noting high sodium content.
