Matcha is the only tea in the world where the leaves are deliberately grown without sunlight. For three weeks before harvest, the tea fields in Uji are covered with tarpaulin canopies that block 80–90% of incoming light. The plants respond by overproducing chlorophyll — that's where the electric green color comes from.
But the bigger thing is amino acids. Tea plants produce theanine, the umami-tasting amino acid that gives matcha its savory quality. Sunlight converts theanine into catechins (the bitter, astringent compounds in regular green tea). By blocking light, growers preserve theanine and prevent catechin formation. The result: a leaf that's high-umami, low-bitterness, and high-chlorophyll — which is what makes ceremonial matcha taste like it does.
Culinary matcha skips the shading. It's grown in sun, harvested late, ground coarser. The result is bitter, gritty, and dull-green. Useful for baking, where the bitterness is masked by sugar; not useful for drinking straight.
Our Uji Matcha is shaded for 21 days, hand-picked, steamed (not pan-fired), de-stemmed, de-veined, and stone-ground at low RPM to prevent heat damage. Each batch is fresh-ground in lots small enough to use within 90 days — matcha oxidizes fast and turns brown if it sits.
How to tell good matcha from bad without tasting: look at the color. Ceremonial-grade matcha is electric, almost neon green. Culinary-grade is dull, olive-tinted, sometimes grayish. The brighter the green, the higher the theanine, and the better the cup.
