Review: Great product - Works each time
Review: A little dab will do ya - Works very well. I have tried one other brand that worked, but had mixed results. This consistently makes a nice koji rice "mat" every time with little maintenance. I am using roughly 1/8th of a teaspoon to inoculate and have my temperature between 85-90 degrees Fahrenheit and my humidity between 79 and 82 percent with the rice between two pieces of cloth. I then flip the rice every 12 hrs until 36-48 hrs have passed and haven't had a failure yet. Will most definitely buy again.

### ⭐⭐⭐⭐⭐ Great product

### ⭐⭐⭐⭐⭐ A little dab will do ya
*by J***L on December 21, 2021*

### ⭐⭐⭐⭐⭐ Good Stuff
*by M***E on October 20, 2021*

Works good. Used for amazake and working on sake. Spores are white, so it can be hard to tell when it has spored. I used a microscope and saw unopened pods at about 50hours. Recommend not letting it go longer. This makes 15kg koji, but because most recipies use only a fraction of koji to rice, it will last a long time.
