Steady Matcha

Best Lab-Tested Matcha Brands in 2026

The best lab-tested matcha brands publish a Certificate of Analysis (COA) from an independent, accredited lab showing specific heavy metal values for every batch - not just a tested badge. In 2026, only a handful of brands meet this standard: Steady Matcha and Encha are the most transparent.
