The matcha industry has a grading problem. "Ceremonial grade" is not a regulated term. Any producer can print it on any tin. The result is a tier that ranges from genuinely exceptional single-origin powder from Uji to green dust that is functionally indistinguishable from mid-grade culinary, sold for four times the price with a calligraphy logo.
What the grades actually mean
Before grading, the leaves are shaded for the final weeks of growth. This increases chlorophyll and L-theanine content, deepening the colour and shifting the flavour toward umami sweetness rather than bitter astringency. Ceremonial grade uses the youngest leaves from the first harvest (ichibancha). Culinary grade uses older leaves, later harvests, or a blend.
If a matcha is bitter and astringent when whisked straight with hot water, it was not grown or processed with enough care to be called ceremonial. The label doesn't change what's inside the tin.
What to actually look for
Colour: vibrant, almost electric green. Dull or yellowish powder is oxidized or low-grade. Texture: fine enough that it feels like silk between your fingers. Coarser powder is culinary. Smell: fresh, grassy, slightly marine. Flavour when sipped straight: sweet, umami-forward, with bitterness that fades cleanly rather than sitting on the palate.
Producers worth trusting
Ippodo and Marukyu-Koyamaen for Japanese sourcing. Kettl for curated Japanese imports in North America. For cafés: ask where the matcha is sourced. If they don't know, that's an answer.
