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.

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.

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.

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 loves cool, dark, and dry. Before opening, keep it refrigerated to help preserve freshness. Once opened, seal it tightly and store it somewhere cool and dark, away from heat, light, moisture, and strong odors. Avoid moving an opened bag in and out of the fridge, since temperature changes can create condensation and lead to clumping. For the most vibrant color and flavor, enjoy it within about a month of opening.

Every order is covered by our 60-day, 100% money-back guarantee. If Tenzo isn't for you, we'll make it right — no hoops.
