Unlocking Umami, Tenderness and Next Level Browning
Koji is one of the most powerful natural flavor enhancers in the culinary world. Used for centuries in Japanese cooking, Koji is a type of rice or barley inoculated with a mold called Aspergillus oryzae. It is responsible for creating iconic ingredients like soy sauce, miso, mirin and sake.
When applied to beef, Koji can dramatically improve tenderness, deepen flavor and supercharge crust formation when searing or roasting. Think of Koji as a natural dry aging shortcut that brings out a richer, beefier flavor in a fraction of the time.
Koji transforms beef through three key processes that create restaurant-quality results at home
Koji contains natural enzymes like proteases that gently break down tough muscle fibers. This results in a tender, silky bite without making the meat mushy.
Koji increases glutamates in the meat, which enhances savory depth. The beef tastes richer, more aromatic and more complex, similar to a dry aged steak.
As Koji breaks down surface proteins and carbohydrates, it accelerates the Maillard reaction. That means:
Three proven methods to transform your beef with Koji
Most Common Method - Creates a dry aged effect in 24 to 48 hours
This method gives you deep flavor without overpowering the beef.
A faster, salt-forward method that produces incredible tenderness
For brisket, prime rib or picanha
Apply Koji powder 24 to 36 hours before cooking for optimal results.
This technique boosts bark formation and enhances the meaty flavor of big cuts.
General guidelines for optimal results:
Ribeye, strip loin, filet
Flank, skirt steak
Brisket, prime rib, picanha
Important: Going too long can cause the surface to break down too much and turn pasty, so staying within these windows is ideal.

Everything You Need to Know About Using Koji on Beef
The Ultimate Technique for Next Level Steak
Koji alone can transform beef, giving it dry aged style tenderness and deep umami. The Japanese Triple Sear technique builds layers of caramelization, umami and aromatic complexity through repeated searing with sake, whiskey and aged shoyu.
Combine the two and you get one of the most powerful steak techniques possible. Koji elevates the flavor of the meat from the inside out, while the triple sear creates an insanely crunchy, glossy crust with a flavor depth you cannot get from standard grilling or pan searing.
If you want the richest, beefiest, most umami packed steak you have ever made, this is the method.
Koji breaks down proteins and carbohydrates on the surface, creating the perfect canvas for browning. Each sear step browns faster, darker and more evenly.
The triple sear adds sake, Japanese whiskey and aged shoyu. Koji amplifies these flavors, making each pass richer and more savory.
Koji tenderizes the interior gently, which pairs beautifully with the high-heat exterior searing.
Because Koji preps the surface, each sear step bonds and caramelizes more aggressively. The final crust is thick, crunchy and packed with complex flavor.
