2. How To Grow Wasabi

To grow wasabi requires a cool place and a lot of clear water. It is grown in the shade as it is intolerant of high temperatures and direct sunlight. Based on these conditions, there are 2 ways to grow wasabi.

Water-grown wasabi: It is grown in fountains of valleys or streams. Since it specifically needs plenty of clean water of a particular temperature, not a lot of places produce water-grown wasabi in Japan.

Farm-grown wasabi: It is grown in humid and cool places or greenhouses. Its root doesn’t grow as big as water-grown wasabi’s.

4. Real Wasabi And Wasabi Paste

Most wasabi paste (usually in a tube) seen in daily life does not contain real wasabi at all or is mixed with horseradish (a kind of radish produced in Northern Europe and Hokkaido in Japan). Real wasabi is usually grated to be eaten. Its pungency and flavor are strongest 3-5 minutes after being grated, and after another 30 minutes you will feel wasabi is delicious. Real wasabi is much better in taste and flavor. On the negative side, it is produced less and is more expensive. Furthermore, it does not last long as the component of the flavor goes bad easily. On the other hand, horseradish is easy to process and is cheap. Therefore, it is often used for wasabi paste.
