Making miso is very simple. As the ingredients are rice, soybean, and salt only, the difference in taste is obvious. It is said that 80% of the taste depends on the quality of rice malt. Rice koji is made by the traditional "ita malted rice" method over 40 hours. Making good koji is very important for making miso. We do not make koji by machine, we take time to make it carefully. The miso warehouse protected by miso craftsmen is a small warehouse without mass production equipment, but craftsmen continue to stick to natural brewing that can be done by hand.
