Kuro Koji Starter (Packet) - Black Koji

$25.00
Limit 5 per order

Black koji is the parent of white koji and it goes further in every direction. More citric acid, a deeper and earthier aroma, and spores that are genuinely black — they'll stain a cloth and dust a countertop, so I make it on a day I'm already cleaning.

This is the strain behind awamori in Okinawa. In my kitchen it goes into a sharply tart amazake, into shio koji for grilled meat, and into anything where I want the sourness to have some weight behind it.

It's the most advanced starter I carry. I'd make rice koji with a standard strain once or twice before trying this one.

  • If you like fermentation and want to make Shochu at home, try this new Koji starter. In addition to Shochu, you can also make Amazake, Soy Sauce Koji, and Salt Koji. The taste will be refreshing with solid citric acidity. Making Koji is the same as that of A.Oryzae Koji, but it is more complex than A.Oryzae. (1) Easy to dry, (2) The temperature rises quickly.

    Compared to A.Oryzae, it dries out more quickly. It is recommended to lightly humidify it with a mist on a cloth-covered sheet during the process. The standard time for Koji to appear is about 40 hours, which is faster than Oryze Koji.
