Shirayuri Koji [Aspergillus oryzae] Spores Gluten-Free Vegan - 10g/0.35oz

Works! I made koji.. much better than the product I had got at the beer store.

I ordered this to propagate on barley grain, I use it for many fermentation projects in my kitchen. Worked great!! I love using it to “dry age” steak.

used to make sake and shoyu. works great

Used to make Koji rice. Worked great!

Was great for making koji rice and I plan to try using it for fermenting soy paste. Exactly as advertised

I grew koji successfully with this. The first time I didn't get the rice moist enough and it kind of petered out, but the second time My koji was healthy and smelled amazing. I still have about 1/4 of the packet left, you definitely don't need to use all of it to do a batch of koji rice. I was surprised that it was a white powder, not spore colored, but it works great.

Much appreciated, good price and well shipped.

Works awesome for soy sauce making
