Review: New to Koji? This is a great starting product - Got this because I wanted to get into Koji and use it to "dry age" meats. I scrutinized whether this was aspergillus oryzae or not like the one offered from Cold Mountain but it wound up not mattering much. What I do to make the Koji powder is blend this rice in a blender until completely powdered. Pop that in a small plastic container and it can keep at room temp for several months. Then when I'm ready to use it, I generally coat the entire surface with the flour and pop the meat in the fridge. Before cooking be sure to rinse all of the Koji off using cold water. I haven't had the chance to use the flour to inoculate my own grains yet. But I'm pretty sure it would still work. Anyway this stuff made the best steak I've ever had. It just enhances the flavors that are already present. You might get some more flavor nuance depending on several things but this is a solid product.
Review: Good Japanese food - I use this to make Miso paste. I am glad I can get this on desertcart!

## Questions & Answers

A: I wouldn't freeze it because I wouldn't have it around that long.

A: Mine has been open but I put it into a large Ziploc. It's fine at room temp as long as it's dry and not exposed to moisture.

A: Miyako Kouji is produced using both white and yellow kouji.

**Q: How do I make more koji using this?**

### ⭐⭐⭐⭐⭐ Good Japanese food
*by K***M on December 3, 2025*

I use this to make Miso paste. I am glad I can get this on Amazon!

### ⭐⭐⭐⭐⭐ Still Pricey But Better Value Than Than Premade Amazake
*by K***R on April 12, 2024*

If you're buying it to make amazake 甘酒, what you can get out of a bag is cheaper than buying those pre-made pouches where you get 2 servings at most. Probably can save even more buying 2 bags at a time, but this was my first attempt at making amazake, and I was intimidated out of buying 2kg at once. The amazake I was able to make with this using an instant pot method was perfect. Just as sweet as the pre-made pouches I had previously purchased on Amazon where you just add hot water. I enjoyed drinking the amazake as well as using it as a sweetener in my cream of rice. I recommend trying fresh ginger in your amazake. The spice from ginger is a nice contrast to the sweetness of the amazake.
