This strain produces, unlike other strains, white spores. It is best suited for amazake, but can be used for light misos as well. If your main aim is to make amazake, you are best off with this strain.

The fragrance this strain produces is outstanding, in my opinion. It also grows well on barley.

    Loving it so far. Using pearl barley right now and it never failed for me. The yield is also slightly more than prescribed, so that’s great aswell!

    Excellent product- very active and copious . I mixed the kojikin with potato starch, because it said in the instructions to mix it with starch to facilitate handling. Next time I will take rice flour and sterilize before mixing in the spores. I am very satisfied with the ease of procedure, the product arrived very quickly. I can fully recommend fermentation culture. I am wondering if they will organize a workshop in shout making one day in beautiful Austria ? Servas und Pfiat‘Enk

    Took a little time to grow. Maybe too low temperature in the beginning but next time ill take the green ones for koji rice.

    Lively spores, I got nice fuzzy grains, they’re almost cute. Made shio koji and amazake with them, tasty results. Second time ordering these. (Get a sousvide like thing for the amazake, it makes everything easier!)

    I feel that they taste more acid than the ones I used to order before here, but still very nice flavour, just less flowery in taste.
