Many of the Japanese were astonished that "American’s" managed to find the secret of growing wasabi out of it’s natural habitat. There were several occurences of "spying" on our farm to learn how we were growing it including fly by’s with airplanes and a helicopter. Wasabi is a degree or so milder than horseradish and has a sweeter cleaner aftertaste. It should only be used in very small portions until one is accustom to it’s flavor. The typical serving size is 3 grams or 3/4 of a teaspoon.
