There are noticeable differences found in Kameya’s premium Wasabi Japonica plants vs. the artificially food-colored horseradish commonly found in most U.S. markets.
Real Wasabi's natural color is generally a soft muted green (not the neon green you may have grown accustomed to).
In Real Wasabi - made from only Wasabi Japonica plants - there is absolutely no food coloring, horseradish, or mustard added.
