Five Matcha Myths We Hear All the Time (And What's Actually True)

Working behind a matcha counter every day means hearing the same handful of myths on repeat. Some are harmless misunderstandings, others lead people to brew matcha incorrectly or avoid it for the wrong reasons. Here are five worth clearing up.

Myth 1: Matcha is just powdered green tea

Not quite. While matcha does come from the same plant as regular green tea, the growing and processing methods are entirely different. Matcha leaves are shade grown for weeks before harvest, steamed, and stone ground into a fine powder, while regular green tea leaves are typically grown in full sun and simply dried and steeped, not consumed whole. The shading process specifically is what gives matcha its higher concentration of chlorophyll, L-theanine, and that distinct umami flavor.

Myth 2: Matcha has way more caffeine than coffee

This depends heavily on serving size and preparation. A typical bowl of matcha contains a caffeine amount broadly comparable to a cup of coffee, sometimes a bit less, though it varies by grade and how much powder is used. What differs more is how that caffeine is experienced, since the L-theanine in matcha tends to produce a steadier, calmer form of alertness rather than coffee's sharper spike.

Myth 3: All matcha is the same, so cheap matcha is fine for drinking straight

Matcha grades vary significantly, and this matters most when you're drinking it on its own rather than mixing it into something like a latte. Culinary grade matcha, often grown without shading and ground more coarsely, tends to taste more bitter and astringent. Ceremonial grade matcha is specifically cultivated and processed for drinking straight, with a smoother, naturally sweeter flavor that doesn't need sugar or milk to be enjoyable.

Myth 4: You need to whisk it for a long time to get foam

Excessive whisking doesn't necessarily produce better foam. Technique matters more than duration. A quick, brisk whisking motion in a W or M shape for around 15 to 20 seconds typically produces a fine, even foam, while slow circular stirring tends to leave clumps no matter how long you continue.

Myth 5: Matcha goes bad quickly so it doesn't matter how you store it

Matcha is sensitive to light, heat, humidity, and air exposure, all of which accelerate flavor degradation. Storing it properly, in an airtight container, away from light and heat, away from the stove, makes a noticeable difference in how long it stays fresh. An opened tin kept properly should still taste good for weeks, while one left out in sunlight can lose its vibrancy within days.

Understanding these distinctions doesn't just make you sound informed at a dinner party. It genuinely changes how good your matcha tastes at home.
