Room Temperature Storage

Room temperature (15-25°C) allows continued microbial activity and gradual aging. Color deepens and umami intensifies.

Summer heat accelerates fermentation — be aware. Avoid sunlight, choose spots with minimal temperature fluctuation. For those wanting to engage with miso as something living, room temperature is recommended. Aging at room temperature over a year develops deep color and strong umami like red miso. Time-aged miso becomes so flavorful it works as a seasoning without cooking.
