The Miso Master Difference

Since 1979, Miso Master has been handcrafting miso using traditional Japanese methods, including natural fermentation for a smooth, unadulterated umami flavor.

Proud to be Organic, Non-GMO, Gluten-Free and Kosher!

Our products are certified Plastic Neutral by rePurpose Global, meaning your purchase helps to fund plastic recovery programs in the areas of our planet that need it most. These programs empower at-risk populations with safer working conditions, stable employment, and formal waste management systems that recover, reuse and repurpose plastic waste from the environment.

What Makes Our Mellow White Miso Superior?

Our miso is crafted using traditional Japanese production methods. That means making our own koji rice, limiting the ingredients we use, and allowing our miso to age naturally without the addition of yeast, fermentation accelerants, alcohols or artificial flavor enhancers. Enjoy the umami flavor that comes with the patience of natural fermentation.
