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.

    I thougt starting my first koji project would have more hiccups, but everything went smoothly. Prices are on point, shipping time was also good. I actually sucessfully grew koji with it. I can’t really talk about the finished product, cuz my red miso is only 3 months in (aiming for 6 at least), but already smells good. I’m genuinely happy that someone just across the border is doing this kind of niche thing. If I wanted to start another koji project I would definitely order from here again. Thank you!

    Delivery was fast, well labelled and accompanied by an explanatory leaflet.
    For me, this was the first experience using spores to make koji. I used these spores to inoculate basmati rice and all when fine.
    I used the koji to make different short fermentation miso from soya beans, split peas, and dark lentils + dried porcini mushrooms. I made also a long fermentation batch with soya beans.

    Super fast delivery. Great quality that allows me to produce perfect Koji from different types of rice even with my selfmade stuff. Can 100% recommend the spores!

    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.

  37. Jean-Luc (verified owner) –

    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.
