Ceremonial grade matcha is a made-up marketing term and is basically meaningless. The quality variability is enormous from vendor-to-vendor and the terms are completely unregulated. Anyone can use these terms and tea ceremony practitioners are definitely not the gate-keepers of quality that the name implies.

Washing products in a “ceremonial grade” label makes it much more difficult for consumers to differentiate between high and low quality products. Ultimately the classification of “ceremonial grade” commodifies products.
