Lab testing & Quality Assurance

In addition to being certified organic, every batch of our matcha undergoes thorough testing in Japan and independent testing here in the U.S. We screen for radiation, microbial contaminants like mold and yeast, heavy metals, and more. Our matcha meets even the strictest heavy metal standards, including California’s Prop 65 guidelines. You can sip Poṣaṇa matcha with confidence, knowing it's as pure and safe as it is delicious!
