Buy Seiun Matcha by Yamamasa Koyamaen

Discover quiet sophistication in every sip with Seiun Matcha by Yamamasa Koyamaen, a premium ceremonial-grade Uji matcha celebrated for its deep umami, creamy sweetness, and radiant emerald hue. Named Seiun (青雲, “Blue Clouds”), this blend evokes clarity and calm — a tea made for peaceful moments and refined taste.

About Seiun Matcha

Seiun is crafted from hand-picked first-flush (ichibancha) leaves shaded for over three weeks before harvest. This long shading period heightens chlorophyll and L-theanine, creating a naturally sweet, mellow taste. The leaves are then steamed, dried, de-veined, and slowly stone-milled to achieve an ultra-fine, silky powder that dissolves beautifully in water.

The result is a matcha with exquisite smoothness, elegant aroma, and a long, clean finish — ideal for both usucha (thin tea) and koicha (thick tea).
