What process applied to Matcha plants before harvest encourages the production of L-theanine and chlorophyll?
Answer
Shading the tea plants from direct sunlight for several weeks.
The characteristic brilliant green color and enhanced flavor profile of Matcha are achieved through a specific cultivation technique implemented before the leaves are picked. The plants intended for Matcha are subjected to deliberate shading, blocking them from direct sunlight for a period spanning several weeks. This environmental manipulation causes the plant to alter its chemical composition: it reduces the production of catechins, which are associated with bitterness, while simultaneously promoting higher levels of L-theanine, an amino acid contributing to sweetness and calm alertness, and boosting chlorophyll, which deepens the green hue.
