It starts at the source. Tenzo is Japan-sourced, farmer-direct, and quality-tested. We work directly with our growers in Japan, cutting out unnecessary middlemen and building long-term relationships with the people behind our matcha. Every batch is tested in Japan and independently validated in the U.S. for heavy metals, lead, and other contaminants, so you can feel good about what goes into every cup.

Most people start by swapping out their morning or afternoon coffee with Tenzo. But it's fine to drink Tenzo whenever you find yourself needing more mental clarity, energy, or focus. For the best results, use Tenzo to make similar drinks to the ones you already love. For example, black coffee = pure matcha and water. If you like adding cream and sugar, try that with Tenzo. Keep testing to discover what works and tastes best for you.

You’ll need an electric mixer, whisk, shaker, blender, or frother. You don’t technically need tools, but they are recommended for a good experience or a unique recipe.

The short answer is, "Yes!" We understand your concern for radiation and other contaminants in the products you consume. Our supply chain is kept under a close watch and we follow Good Manufacturing Practices with every batch of matcha that we import from Japan. We have our products tested regularly for radiation and other contaminants such as heavy metals. There are no detectable levels of radiation or heavy metals found in our products.

While our product is safe for most individuals, it’s best to consult with a healthcare professional for specific recommendations regarding children and caffeine consumption.

There are plenty of ways to make matcha, but you can keep it simple. Mix your matcha with a small amount of cold or warm water until smooth, then enjoy it straight or add your milk of choice. For hot matcha, aim for about 158 to 176°F and skip boiling water, which can bring out more bitterness and astringency. For a softer, smoother cup, cold-whisking naturally brings out more sweetness and less bitterness.

Matcha is naturally rich in antioxidants, including EGCG, and contains both caffeine and L-theanine. Together, these compounds can support calm, focused energy, mental alertness, and overall wellness—one of the reasons matcha fits so naturally into an everyday ritual.

Matcha naturally brings caffeine and L-theanine together. The result is a smoother, more sustained lift with a calmer, more focused feel than the jitters often associated with coffee. Caffeine levels vary by blend, harvest, and preparation, but the experience is part of what makes matcha feel distinctly different.
