・About the finised amount:
If you steam the rice, the steamed rice will be 1.8-2 times heavier than original/raw weight.
Then, after the koji rice is completed the weight will be 0.9 times of the weight after steamed. Thus, the finished amount of rice koji will be 1.62 (1.8ｘ0.9)～1.8 (2ｘ0.9) times from the weight of original/raw rice.

I live abroad. Last year, I bought the "Koji Starter - Powdered Chouhaku-Kin Fungal Seed" and I made miso, shio koji (salt koji), shouyu (soy sauce) koji, and mirin.
This year I wanna try making barley miso, so I bought this product
Because I live in overseas, it's expensive to buy miso and there are miso that's not delicious.
I'm glad that I can make it myself.
In the process of making koji rice, I could smell koji's unique aroma and was unbearably getting happy.
Last year's miso is still being fermented, and I'm really looking forward to the completion!
This year I will challenge myself to make barley miso. I'm really excited!
I made koji rice with 5.4 liters of white rice.
Made using electric blankets, and the result is 5 kg of koji rice.
We ordered the koji starter, and thanks to the fast response of Kawashima-ya shop, the koji can be finished on my day off. Thank you!
I challenge myself to make my own koji for the first time.
I entrust the temperature control to Yogurtia device, and I use Akitakomachi rice for the ingredients.
Until the second maintenance, from my amateur eyes there's not much change in the koji and I got excited about how well it can be done. But after 40 hours, the fluffy koji rice was completed!
Next time, I want to make barley miso with barley koji.
The Benefits of Handmade Koji Rice
- ■ You know exactly what ingredients are being used. Formerly, in the Japanese family, miso, shouyu, amazake etc. were homemaded with koji. However, the eating habits change with the time, and miso, shouyu, amazake changed from "things to make" to "things to buy." Under such circumstances, there are many people who are uneasy because they don't know what type of rice is used, in foods such as miso and shio koji (salt koji) available at supermarkets etc. If it's handmade, you can make it with pesticide-free rice prepared by yourself so it's safe.
- ■ Handmade is fun! When Kawashimaya's staffs tried to make handmade koji rice, they're impressed that their hands became so smooth. It's a famous story that because they engage in sake-making, the hands of chief brewer at sake (Japanese liquor) brewery is beautiful. In koji rice's nutrients, there are a lot of components that make the skin beautiful. Then, if you make koji rice by yourself, you will take care of it like your own child. Thus, the miso and amazake you made will become more delicious.
- ■ It's more economical. When making miso, you will need koji in kilograms. If you buy it, it will be really pricey. For that, if you make your own koji using koji starter (Apergillus oryzae), it will be much more economical because you can even make koji rice from 15kg of rice.
- The Steamed Rice, is What Determines the Quality of Koji Rice
- If the rice used in koji rice making is cooked with rice cooker or the like, the amount of water (60% or more) becomes too much, and it won't be finished as a good koji rice.
In order to make the rice with moderate water content (about 38%), it's necessary to "steam" the rice with proper steam.
The professionals in koji-making are making steamed rice with bamboo steamer (seiro).
Furthermore, by using steaming cloth made of tetoron, the time loss (temperature drop) caused by the rice sticking on the cloth can be eliminated, so you can do the seeding step (sprinkling the koji starter on steamed rice) smoothly.
