A standard 2 gram serving of matcha contains roughly 60 to 70 milligrams of caffeine. That's about two thirds the caffeine of an average cup of brewed coffee, around the same as a strong cup of black tea, and noticeably more than a cup of green tea brewed from leaves. The exact amount depends on the grade of matcha, the harvest, and how much powder you use per cup.

Matcha caffeine works differently from coffee caffeine, which is why so many people switch. The energy hits softer, lasts longer, and rarely comes with the jittery edge or the afternoon crash. Two ingredients are doing the work.

The L-theanine effect

Matcha contains a high concentration of L-theanine, an amino acid that promotes calm, focused alertness. L-theanine slows the absorption of caffeine into the bloodstream, which means the energy from matcha builds gradually and tapers off gently rather than spiking and crashing.

This is why a morning bowl of matcha can keep you steady for four to six hours, while the same caffeine dose from coffee might give you a sharp two hour lift followed by a slump. The combination of caffeine and L-theanine is also linked to improved focus and a calmer alertness, which is why matcha is popular with people who need to concentrate for long stretches.

The whole leaf factor

When you drink matcha, you're consuming the entire ground leaf rather than an infusion. Steeped tea only gets you what dissolves into the water. Matcha gets you everything, which means more caffeine per gram than the same weight of brewed leaves, and more antioxidants, more chlorophyll, and more L-theanine.

Caffeine by serving size

Most people make matcha at one of three strengths. Here's roughly what each delivers.

A traditional bowl of usucha (thin tea), made with about 2 grams of matcha, contains 60 to 70 mg of caffeine.

A daily matcha latte, often made with 3 to 4 grams of matcha, contains 90 to 140 mg of caffeine.

A bowl of koicha (thick tea), made with 4 grams of matcha or more, contains 120 mg or more of caffeine.

For comparison, an espresso shot contains around 60 to 80 mg of caffeine, a standard cup of brewed coffee around 95 to 200 mg, a cup of black tea around 40 to 70 mg, and a cup of green tea brewed from leaves around 25 to 35 mg.

Should you worry about caffeine intake?

Health Direct Australia notes that healthy adults can safely consume up to 400 mg of caffeine per day, which is around 6 to 7 servings of matcha. If you're sensitive to caffeine, pregnant, or watching your intake, start with a 2 gram serving and see how you feel.

Teafy's Ceremonial Grade Matcha Powder is medium caffeine, around 60 to 70 mg per 2 gram serving. Our Hojicha Powder is much lower, around 7 to 14 mg per cup, because the roasting process reduces caffeine significantly.
