Tasting Kinzanji miso
The Kinzanji miso is a success! The rice fermented into a very soft paste that holds the whole thing together, the barley is soft but springy, and the soybeans are still nice and firm. It’s quite sweet but also tart and tangy, just right as a veggie or rice topping. Now the final trick will be giving it all away, because there’s no way we can eat 11 kilograms!

Making Kinzanji miso
Making Kinzanji miso takes three days of work—not continual work, but work timed at intervals such that it’s hard to do too much more than just make miso. Luckily for us we were guests of the woman in charge, and she did all the off-hours tasks.
Prepping the grains
The first day we arrived early in the morning and built fires for steaming the grains. We had one portable gas stove and the stove in the kitchen, and we also built three fires in the bays of the traditional stove and one under the outdoor steamer. A hot business, that, in August! I had my face close in to the fires until someone pointed out the length of bamboo with a hole poked in the distal end–a great way to blow on a fire from afar. It was a bit of a tap on the shoulder about our preconceptions, what we look for and what we overlook in going about our everyday affairs.
The rice had been soaking overnight, and was put on the steamer. While it was steaming for the first hour we hulled the soybeans in a hand mill, then separated the skins with a traditional tool—see videos of these steps below.
The barley and soybeans got mixed and were stacked on the steamers, so the rice was on for a total of two hours and the barley/soy for one.
Both were cooled to 37 degrees C and the special koji mold was mixed in. The rice was mounded in large containers and loosely covered with a moist cloth to prevent drying; the barley/soy mix was spread out in wooden trays with only newspaper draped over to prevent bugs from getting in.
Here we took a break and a welcome shower. Five hours later, in the evening, we poured the barley/soy back into large containers and gave it and the rice a good mixing to make sure the mold culture was evenly spread. The mold was very apparent on both by this time.
Koji mold fermentation
Many people are probably thinking that moldy food = bad food. Really, the only difference between fermented foods and spoiled foods is the type of microorganisms that are present in them. If you’ve ever had yogurt, cheese, beer … you’ve benefited not only from lactobacillic organisms, but also from yeasts, molds, and much more. As most experienced fermenters know, white mold is usually a good sign, and can be scraped off before eating. Molds of any other color are bad, the darker the worse, and their presence means a good cleaning and starting the project from scratch.
One other note on molds, or any microorganisms really, is that culturing is as much a numbers game as anything else. The salt in sauerkraut and other lacto-fermented foods is there to inhibit the growth of baddies while the desired cultures increase. When a miso maker we know up in the mountains moved into an old elementary school, he first took handfuls of his mold culture and threw it all over the walls, ceiling, and in every cranny of the room that was to be his culturing room. As anyone who’s been in old school buildings here knows, they’re havens for mold and who knows what else—he had to make sure that his mold was the only one growing in his culturing room.
But I digress … we gave our moldy grains a good mix and put them down for the night.
Lacto-fermented vegetables prep
The next afternoon we arrived and started preparing the ginger, eggplant, and ‘uri’ white gourd for pickling. After putting them down with salt we took off until the evening, when we returned to process the shiso leaves and sesame seeds.
Late that night our hostess mixed some salt into the rice and barley mixtures, stopping the koji mold fermentation. When we arrived for our last morning the only thing left to do was to mix the rice, barley/soy mix, and all the vegetables together evenly. We divided it up into buckets, and that’s where it’s been sitting for a month.
What a process! I definitely see why you’d want to do a hundred pounds or more at a time, but would encourage anyone with an opportunity to make miso to give it a try. At the very least you’ll have twenty-some pounds of reminder of your labors!
