What is Koji Starter/Koji Seed?

Koji starter or koji seed is the Aspergillus spore that becomes the source of koji.

In the brewing industry, we call the koji starter "sprouts". We can make koji to produce fermented foods such as miso and amazake (sweet sake) with these sprouts.

The appearance of the koji starters bud popped out, and its whitish hyphae grow the bean sprouts and budding trees figure, so it's called like that.


What is Koji?

Give water to raw grains (rice, barley, beans, etc.), sprinkle seeds on steamed grains, and culture the seeds under temperature conditions suitable for the growth of Aspergillus oryzae.That is how this koji starter is made.

Koji has so many enzymes that it is said to be a treasure house of enzymes and could decompose grains with its power. Also, koji itself is a nutritious food filled with sugar, amino acids, vitamins, minerals, etc. All these nutritions are made by the koji starter (Aspergillus oryzae).
With koji, you can make traditional fermented foods such as sake, authentic shochu, mirin, miso, soy sauce, vinegar, amazake (sweet sake), etc.

・ If you want to store the koji rice for 2-3 days, please put it in the refrigerator.
・ If you want to store it for more than 3 weeks, please put it in the freezer. In the freezer, the koji starter can be saved until 3 months.

Can I drink koji starter as it is?

Since it's not a drink, please do not drink it. If you look for a supplement product, we recommend you to try KAWASHIMAYA "Lactic Acid Bacteria Powder" - Probiotic Supplement Taken from Japanese Fermented Foods (100 g)

How much should I use the koji starter when making koji rice?

The amount of koji starter is about 1.3g-10g for 1kg of rice (rice for raw material) (about 0.2g-2g per 150g of rice).
If you are still not used to koji rice making (first-time try), it's better to use the koji starter more.
Because even if you use much of it, there will be no problem.

About the finised amount:
・ The steamed rice will be 1.8-2 times heavier than the original/raw weight if you steam the rice.
・ Then, after the koji rice is completed, the weight will be 0.9 times the weight after steaming. Thus, the finished rice koji will be 1.62 (1.8x0.9)~1.8 (2x0.9) times from the original/raw rice weight.
・ For example, if the raw rice is 1kg, the finished amount of koji rice is 1.62-1.8 kg.
(This is an estimated amount. The amount of finished koji rice depends on the soaking condition, steaming condition, and the condition of fermentation process).

The color of the finished rice koji is reddish-brown and smells strange. Can I use it?

There is a high possibility that other bacteria are mixed and increasing in the process of making it. Please don't use it.

After you have sterilized all the equipment, please try increasing the amount of koji starter when making koji rice next time (about 3-4 times more) so it's easier to ferment.

In addition, please be careful about temperature control during the fermentation process.

How to Make Koji Rice — Without Fail!
how to make koji
Koji is a famous mold that is popular in Japan. It is the basic foundation of amazake, soy sauce, sake, and other traditional Japanese fermented foods. The mold, scientifically called Aspergillus Oryzae, is usually inoculated on all kinds of steamed grains like rice, soy, or barley. To make rice koji, steamed rice is sprinkled with koji starter (koji seed) and kept at a controlled temperature. When the mold starts to cover the rice grains, the koji is done and can be used as an ingredient.
