What is the approximate shading duration for Matcha's base, Tencha?
Answer
Closer to three or four weeks
The duration of light deprivation is a crucial differentiator among shaded teas. While Gyokuro bushes are typically covered for around three weeks prior to picking, the leaves destined for Matcha production, known as tencha, undergo a more intense shading period, often lasting closer to three or four weeks, or even longer. This extended shading maximizes the chemical changes, boosting the desirable compounds like L-theanine even further before the leaves are dried (without rolling) and eventually stone-ground into the final Matcha powder.
