Why Japanese Tea Farmers Block the Sun

Mei Leaf Guide 22 days ago

Description

Ever wondered why Japanese tea farmers cover their tea bushes with tarps and scaffolding?

In this video, Don breaks down the science and art of shade-grown Japanese green tea. Learn how reducing sunlight alters the leaf’s chemistry—preserving the relaxing amino acid L-theanine while decreasing bitter catechins—to produce an intense umami and silky, brothy mouthfeel.

We brew and taste three distinct styles back-to-back to showcase exactly how shading levels shape character, flavor, and texture:

JAM ROCK SENCHA (unshaded): https://meileaf.com/p/tea-isec
A rich and raucous ride made from the alpine landscape of Tenryu. Jams, doughnuts and minerals with an energetic body sensation.

OKUMIDORI KABUSE (14-day shade): https://meileaf.com/p/tea-okac
Kagoshima Kabusecha made from the Okumidori cultivar. This is ultra-luxurious, soft smooth, sweet and creamy.

GYOKURO KARIGANE (Full 30 day shade): https://meileaf.com/p/tea-kgyc
A blend of Yabukita & Gokou cultivars from Uji, Kyoto. Cultivated under traditional scaffolding and blended 50/50 with shade-grown stems for a luscious, custard-like umami experience without overwhelming heaviness.

HATSU BLACK: https://meileaf.com/p/tea-hblc
A celebration of the original Wakoucha Black Tea using a heritage cultivar hardly ever used today. A wildly contrasting Black both warm, smooth and malty while being fresh with brisk eucalyptus.
