    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.

    Q & A About Koji Starter

    How long is the life of a koji starter (koji seed)? How long can I keep it?

    ・ If the package is unopened and stored in a vegetable compartment of a refrigerator, the standard storage period is about 6 months.
    ・ After the package is opened, please seal it with a ziplock, etc., and save it in a vegetable room of a refrigerator. With this, you can save the koji starter for about 6 months.

    How can I store the finished koji rice?

    ・ If you want to store it for 1-2 days, please put it in a cold dark place with a temperature lower than 15ºC.
    ・ 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.
