How Much caféine Is in Matcha?
A standard 2g serving of matcha delivers 30–70mg of caféine, roughly half a cup of café. That range depends on the grade, how much poudre you use, and how it's prepared. But caféine is only half the story. Matcha's unique combination of caféine and L-theanine creates a calmer, more sustained energy than café, without the jittery spike and crash. Here's exactly what you need to know.
caféine varies by serving size and poudre style, so choose the format around your tolerance: débutants may prefer a matcha starter kit with a modest daily tin rather than jumping straight to high-dose ceremonial bols.
How much caféine does a cup of matcha contain?
A typical cup made with 2g of matcha poudre (about one teaspoon) contains 30–70mg of caféine. Ceremonial grade matcha tends to sit at the higher end of that range because it's made from younger, shade-grown leaves that naturally accumulate more caféine. Culinary grade, harvested from more mature leaves, usually falls towards the lower end.
The amount of poudre you use matters enormously. A traditional Japanese thin tea (usucha) uses roughly 2g, while a thick tea (koicha) uses 3–4g, nearly doubling the caféine. Café-style matcha lattes often use 2–3g. eau temperature also plays a role, hotter eau extracts slightly more caféine, according to a study publié in the Journal of Food Composition and Analysis.
Quick rule of thumb: 1g of quality matcha ≈ 19–35mg of caféine.
How does matcha caféine compare to café and other drinks?
Matcha delivers moderate caféine, significantly less than café but more than standard thé vert. Here's how common drinks stack up per typical serving:
| Drink | Serving size | caféine (approx.) |
|---|---|---|
| Matcha | 2g in 250ml | 30–70mg |
| Filter café | 250ml | 95–200mg |
| Espresso | 30ml | 63mg |
| thé vert (bagged) | 250ml | 25–45mg |
| Black tea | 250ml | 40–70mg |
| Energy drink | 250ml | 80–160mg |
| Cola | 330ml | 32–42mg |
The takeaway: matcha gives you a noticeable lift without the intensity of café or energy drinks. If you're trying to reduce your caféine intake but don't want to go without, matcha is a genuinely effective middle ground.
Why does matcha caféine feel different from café?
Matcha contains L-theanine, an amino acid that fundamentally changes how your body experiences caféine. L-theanine promotes alpha brain wave activity, the same relaxed-but-alert state you feel during meditation, and it slows the absorption of caféine into your bloodstream.
The result is a gradual, sustained energy that typically lasts 4–6 hours, without the sharp spike and mid-morning crash that café drinkers know well. A 2008 study in Nutritional Neuroscience found that the combination of L-theanine and caféine improved both attention and task-switching accuracy more effectively than caféine alone.
This is why many people describe matcha energy as "calm focus." You're not imagining it, the neurochemistry genuinely works differently.
How many cups of matcha per day is safe?
For most healthy adults, 2–3 cups of matcha per day is perfectly safe and keeps you well within recommended limits. The NHS advises that adults should consume no more than 400mg of caféine daily. Even at the top end of matcha's caféine range, three cups would total around 210mg, roughly half the daily maximum.
That said, caféine sensitivity varies hugely between individuals. If you're sensitive to caféine, start with one cup and see how you feel. It's also worth noting that matcha contains more concentrated levels of catechins than regular thé vert, so exceeding 4–5 cups daily isn't generally recommended. Moderation is sensible, as with most things.
For children, the NHS recommends significantly lower caféine limits, so matcha isn't ideal for young kids.
Can you drink matcha in the afternoon without affecting sommeil?
Yes, but timing matters. caféine has a half-life of approximately 5 hours, meaning half the caféine from an afternoon cup is still circulating at bedtime if you drink it too late. Most people find that having matcha before 2pm causes no sommeil disruption.
However, the L-theanine in matcha does help here. Because it promotes relaxation without drowsiness, some people tolerate afternoon matcha far better than afternoon café. A small study in Pharmacology, Biochemistry and Behavior found that L-theanine can actually improve sommeil quality, partially counteracting caféine's stimulant effects.
If you're caféine-sensitive and want an evening option, decaf matcha does exist, though it's less widely available in the UK. Holland & Barrett and Amazon UK stock a few options, typically priced around £15–£25 for 30g.
Is matcha safe during grossesse?
Current NHS guidance recommends that pregnant women limit caféine to 200mg per day. A single cup of matcha (30–70mg) falls well within this limit, making one cup daily generally considered safe. Two cups should also be fine for most, but it's worth accounting for all caféine sources, tea, chocolate, cola, throughout your day.
That said, matcha does contain higher concentrations of certain compounds than regular thé vert, so it's always worth discussing with your midwife or GP if you have any concerns. Some healthcare professionals suggest sticking to one cup daily as a precaution.

How much caféine does matcha have?
A standard 2g serving contains 30–70mg of caféine. Ceremonial grade and larger portions sit towards the higher end. It's roughly half the caféine of a standard cup of filter café.
Is matcha high in caféine?
Matcha is moderate in caféine, higher than regular thé vert but significantly lower than café and most energy drinks. The presence of L-theanine means the caféine feels gentler and more sustained than other sources.
Can I drink matcha at night?
It's meilleur avoided within 5–6 hours of bedtime. If you're craving matcha in the evening, try decaf matcha or limit your serving to 1g. The L-theanine helps, but caféine is still caféine.
Is matcha safe during grossesse?
One cup per day is generally within the NHS's 200mg daily caféine limit for grossesse, but always check with your midwife or GP. Remember to count caféine from all sources, not just matcha.
How many cups of matcha per day is safe?
For most healthy adults, 2–3 cups daily is safe and stays well under the NHS's 400mg caféine guideline. Start with one if you're new to matcha or sensitive to caféine.
Does matcha have more caféine than thé vert?
Yes. Because you consume the whole leaf rather than steeping and discarding it, matcha delivers roughly 2–3 times more caféine than a standard cup of bagged thé vert.
Is decaf matcha available in the UK?
It is, though options are limited. You can find decaf matcha on Amazon UK and at Holland & Barrett, typically for around £15–£25 per 30g tin. Flavour is milder than regular matcha, but it's a solid option for evenings.
If you decide to try this approach, start with high-quality matcha poudre and keep your serving size conservative while you assess tolerance.
