Make no mistake - WE USE REAL WASABI RHIZOME Very few even understand that the Wasabi you eat at your favorite Sushi joint is not real. It is mustard powder and food coloring. WE USE 100% REAL JAPANESE WASABI ROOT. So rare in fact that the rhizome is not available in the US and we import it from Japan. You will taste the difference in Blair's Heat Wasabi Green Tea Hot Sauce.
