Around April, shortly after new shoots appear on the bushes, the fields are covered, with the plants being almost completely protected from sunlight.
In Uji, reeds have been spread on bamboo poles for centuries. Today, only a few farmers still use this traditional method. The shade allows the tea to bundle and increase nutrients. Bushes that are not exposed to sunlight significantly increase the production of chlorophyll.
Also important is L-theanine, the amino acid responsible for the umami flavor in tea. The gentle taste is preserved through the shaded cultivation.
