Tane Koji / Koji Starter

This Kosher-Certified Koji spore is used at Shochu distilleries in Japan.

Koji made from White Koji Spores has a sweetness from the rice decomposition and a sour taste from the naturally-occurring citric acid. The color of the spore itself is somewhere between off white to eggshell color, and the finished Koji has a white color and a beautiful appearance.

You can enjoy a sour taste amazake from the Koji made from these spores, which makes a perfect summer drink.

Instructions:
1. First stage (after applying the koji spores): Maintain the koji temperature within 37~38℃

2. First maintenance (18~20hr after applying the koji spores): Maintain the koji temperature within 35~38℃

3. Second maintenance (25~27hr): Maintain the koji temperature within 35~38℃

4. Third maintenance (30~32hr): Bring down the koji temperature within 32~33℃ and maintain the temperature until completion.

5. Completion: 42hrs after applying the koji spores.

*If an incubator was used for the yellow koji spores (such as koji spores for rice, barley and soy source) previously, make sure that you sanitize the incubator very well. Otherwise, if the yellow koji spores leftover exist, yellow koji spores will suppress the black koji spores which also reduces citric acid production. 

When using a wooden incubator, you can spray 70% proof Ethel alcohol, hydrogen peroxide or boiling water, then wipe it and wait until it’s completely dried.
