Review: Economic method to ferment your own liquid Koji - High quality at a descent price versus the local Asian grocery store. Easy to make your own Koji from the inoculated rice. The is very versatile, adding wonderful umami flavor and tenderizing meats such as fish, beef and pork. It’s more economical to purchase this larger bag of Koji rice and fermenting your own liquid, than purchasing the liquid form. 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. ## Features - Contents: 1kg - Calories: - - Ingredients: Rice (domestic) - Product Size (width ~ depth ~ height): 220 ~ 40 ~ ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004FHB5OO | | Best Sellers Rank | #21,977 in Grocery & Gourmet Food ( See Top 100 in Grocery & Gourmet Food ) #17 in Winemaking Ingredients | | Brand | Isesou | | Brand Name | Isesou | | Coin Variety 1 | Rice | | Container Type | Bag | | Cuisine | Japanese | | Customer Reviews | 4.7 out of 5 stars 2,650 Reviews | | Item Form | Powder | | Item Package Quantity | 1 | | Item Package Weight | 1.02 kg | | Item Type Name | food | | Item Weight | 1.02 kg | | Manufacturer | Iseso Co., Ltd. | | Number of Items | 1 | | Number of Pieces | 1 | | Package Size Name | 1kg | | Part Number | 25080 | | Product Shelf Life | 300 days | | Set Name | Rice | | Shelf Life | 300 days | | Size | 2.2 Pound (Pack of 1) | | Specialty | Vegan | | Unit Count | 35.27 Ounce | ## Product Details - **Brand:** Isesou - **Item Package Quantity:** 1 - **Item Weight:** 1.02 kg - **Number of Items:** 1 - **Unit Count:** 35.27 Ounce ## Images ![IseSo Miyako Koji 1kg - Image 1](https://m.media-amazon.com/images/I/91qZVbC57FL.jpg) ## Questions & Answers **Q: How long will this keep?
