Every batch. Every number. Published.
Most matcha brands say they test. Few publish the actual numbers. We publish every batch COA from Eurofins Scientific - an independent, ISO 17025-accredited lab - with specific values for lead, cadmium, arsenic, mercury, and 200+ pesticide residues.
Why this matters:Matcha is a whole-leaf product - you consume everything in the leaf, including any heavy metals. The only way to verify safety is third-party lab data with specific values, not just a "tested" badge.

The founding batch is in production. Real COA results from our independent lab will appear here at launch. We will not publish placeholder numbers.
Why we publish every number
The matcha industry has a transparency problem. Most brands claim to test but publish nothing. Some publish a single COA from years ago and apply it to all products. A few publish COAs on request - but only if you ask.
We publish every batch COA publicly because we think you should be able to verify what you are putting in your body without having to ask. The numbers are either good or they are not - hiding them helps no one except brands with something to hide.
When our founding batch COA is received, we will publish the specific values here. Every future batch will be published the same way, within 30 days of testing.
