This is a strain for long-term rice misos, also known as red rice miso.

To avoid any confusion: this is NOT Monascus Purpureus. It is Aspergillus Oryzae. We don’t sell M. Purpureus, as it is both hard to source and hard to grow.

    Fast delivery and perfectly packed. I have already used red koji spores that have worked perfectly with the basic solution, oven and hot water bottles. 4 kg of miso are aging, and I did a little bit of shio koji.

    Very good products. I use this strain for making sweet red miso (Edo miso) because it needs just one month of fermentation, I cannot wait 12-24 month for red miso. The sweet red miso tastes delicious.
    I incubated my Koji at 30 degrees C for 48 hours.

    Cultured on basmati rice, at room temp. Kitchen at 25-26°C, rice/koji mat temp at 30-31°C.
    Fully grown at 50 hours.

    rich overripe fruit fragrance.

    Quick and reliable shipment to Switzerland.
