Matcha is shaded before the leaves are picked

Weeks under cover raise chlorophyll and theanine, deepening colour and savour

Tea bushes for matcha are covered with screens for around three weeks before harvest, cutting the light to a fraction of normal. The leaves respond by producing more chlorophyll, which deepens the green, and more theanine, which softens bitterness and adds savour. The leaves are then steamed, dried and ground on stone mills into a fine powder that is drunk whole.
