Like you, our co-founder Dr. Weil is equally picky about what he's putting in his body. It took years for matcha.com to create our matcha-growing collective in Japan to develop what our customers often call "The Purest and most potent matcha on the planet!" It all comes down to the Six (6) Stages of purity and potency required to validate the absolute quality of our tea-farms' matcha. 

The first step in matcha.com's proprietary Six (6) Stage screening is to ensure our products are free of microbial contaminants. These include coliforms, yeasts and molds, and any bacterial presence. Just like heavy metals, radiation, and pesticides – we take the purity of our matcha from any microbial contaminants with absolute concern. Keep reading for each of our six steps. ¹

Next in our Six (6) Stage purity evaluation is to prove that our matcha is compliant with the strictest Heavy Metal guidelines, including those of California. Accredited labs conduct a complete screening for heavy metals and ensure they are not detected whatsoever at unsafe thresholds. Even for those who have a serving of matcha everyday, there are no detectable 'Prop 65 levels' of Arsenic (As), Lead (Pb), Cadmium (Cd), nor Mercury (Hg).²

Step 3 in our official Six (6) Stage testing method provides for one of the most comprehensive pesticides screens of any matcha green tea in the world. Industry-leading instrumentation evaluates our matcha for any presence of more than 500 pesticides. With your health and safety in mind, our tea farm has never once used pesticides, and we're happy to report that absolutely zero tested pesticides are detected in our matcha/green tea. Note: these are accredited equipment with extremely low detection-thresholds for even the most microscopic presence of these toxic pesticides.²

Stage 4 is dedicated to making sure you are confident in our matcha by screening for Radiotactive Isotopes. Our tea farm in Uji, Kyoto and the surrounding region are some of the purest locales in all of Japan for growing premium matcha tea. ALL of our tea produced in this region are screened for any radiation at unsafe levels; our customers can rest easy with matcha.com as your source of radiation-free matcha and Japanese green tea.⁴

Step 5 is part of our proprietary Six (6) Stage method because it deals with the potency of the matcha you're ingesting. Since you want the highest quality matcha from all of Japan, we stand by the mood boosting effects you may experience. Our matcha is tested regularly for healthy concentrations of brain-boosters like L-theanine, synergetic caffeine, nootropic antioxidants, and even theobromine (one of the feel good compounds found in chocolate!). We promise that you'll literally feel the difference that our quality makes.3

Our Six (6) Stage matcha protocol wouldn't be complete without an industry-leading, 'Full Nutritional Panel.' Giving accurate insights about the nutritional value of our matcha products is something that you'll notice sets us apart from most every other matcha brand on the market. Added value of this final step means reporting potency of antioxidants in some of our matcha. Moreover, the specific nutritional data provides details found on our article: "Vitamins found in Matcha.com Matcha"⁶
