What is gyokuro? Like matcha, gyokuro is a shaded Japanese green tea. The difference lies in post-harvest processing. Gyokuro is considered to be the finest loose leaf Japanese green tea.
Around three weeks before harvest, gyokuro leaves are shaded from the sun. Shading contributes to higher operating costs, which makes this tea more expensive than non-shaded teas.
There are two typical methods of shading:
The second method is the simpler, more modern “jikagise” method wherein the leaves are covered with black fabric.
Shading causes the tea leaves to receive limited amounts of sunlight which inhibits photosynthesis. Usually, during photosynthesis, L-theanine converts into catechins, and it will only do so through exposure to sunlight. Thus, if there is no sunlight, then L-theanine starts to build up in the tea plant.
However, too much shading can be harmful to the tea plants and can cause them to die. Finding the optimal amount of shading for each year’s harvest conditions is a special skill developed by gyokuro farmers.
The shading that produces L-theanine has a strong effect on the flavor of the tea. It gives gyokuro its characteristic umami flavor, highlighted with sweet undertones. Additionally, gyokuro has less astringency because it contains less catechins.
As mentioned above, photosynthesis converts L-theanine into catechins, and catechins are responsible for the astringency in tea. Thus, the less photosynthesis, the less catechins, the more L-theanine.
After shading, the post-harvest processing for gyokuro is similar to the processing for sencha.
