Matcha vs. Coffee: Which Has More Caffeine - and Does It Feel Different?

Yes, matcha has caffeine.

Anyone telling you otherwise is oversimplifying it.

The more useful question is:

How much caffeine are you getting, and what else comes with it?

How much caffeine is in matcha?

Caffeine in matcha varies by cultivar, harvest, growing conditions and serving size.

In one controlled study, 2 g of matcha contained about 66 mg of caffeine and 48 mg of theanine. Another study using 4 g of matcha measured 136 mg of caffeine.

That makes a reasonable 2 g serving of matcha roughly:

60–70 mg of caffeine

Coffee varies even more depending on bean, roast, brew method and cup size. A typical brewed coffee often contains more caffeine per serving than a standard matcha.

So in simple terms:

Coffee usually gives you the larger caffeine dose.

What makes matcha different?

Matcha naturally contains L-theanine.

Researchers have studied caffeine and L-theanine together because the combination may support some aspects of attention and cognitive performance. A systematic review found evidence that the combination can improve certain measures of attention, although the research is not strong enough to claim that everyone will experience the same effect.

Studies using matcha itself have also reported improvements in some reaction-time and attention tasks. Researchers have noted that caffeine probably explains part of that effect, while matcha’s theanine and catechins may also contribute.

That is much more accurate than saying:

“Matcha caffeine absorbs slowly and coffee caffeine hits instantly.”

Caffeine is still caffeine.

What changes is the drink around it, the dose and how your body responds.

Does matcha really give you a calmer energy?

Some people describe matcha as feeling smoother than coffee.

There is a scientific reason that idea is plausible: matcha contains caffeine alongside L-theanine, and studies of the caffeine–theanine combination have found effects on attention and cognitive performance.

But we would not tell you that matcha automatically prevents:

• jitters
• crashes
  
• poor sleep

Those depend heavily on the person and the caffeine dose.

If you are sensitive to caffeine, matcha can still feel like caffeine.

Because it is.

Better matcha can actually contain plenty of caffeine

This surprises people.

Shading tea plants before harvest changes the chemistry of the leaf and is associated with higher levels of amino acids such as theanine.

That means a high-quality matcha can still contain a meaningful amount of caffeine.

In one 2 g matcha study, the serving contained 66.2 mg caffeine and 48.1 mg theanine.

So the appeal of good matcha is not necessarily less caffeine.

It is the combination of compounds in the leaf.

Matcha vs. coffee for focus

Research here is interesting, but it is easy to exaggerate.

Caffeine itself has well-established effects on alertness and reaction time.

Studies of matcha and caffeine–theanine combinations suggest possible benefits for attention and some cognitive tasks, but results vary depending on the study, dose and population.

So we would frame it like this:

Coffee can make you alert.

Matcha can also make you alert, while giving you caffeine alongside theanine and other tea compounds.

That is the meaningful difference.

Which one should you drink?

Choose matcha if you:

• prefer a smaller caffeine serving
  
• want caffeine with naturally occurring L-theanine
• find coffee uncomfortable for you personally
• simply enjoy matcha more

Stay with coffee if you:

• love coffee
• prefer a stronger caffeine hit
• tolerate it well
• do not see any reason to change

There is no competition you need to win.

You can drink both.

What about matcha later in the day?

A standard matcha can contain less caffeine than many coffees, but that does not make it caffeine-free or automatically sleep-friendly.

Caffeine can still affect sleep, particularly if you are sensitive or drink it late.

A recent matcha trial used 2.7 g per day containing about 71.5 mg of caffeine. The study did not find significant changes in several objective sleep measures, but that does not mean matcha cannot affect sleep in individual people.

So if caffeine keeps you awake, the same rule applies:

Watch the timing.

Matcha vs. coffee: the simple answer

Coffee generally gives you more caffeine.

Matcha gives you caffeine too, but it also naturally contains L-theanine and catechins.

That combination is one reason matcha has become interesting in cognitive research.

The difference is not that matcha contains some magical form of caffeine.

It does not.

It is the same caffeine, arriving in a different drink with a different chemical profile.

And for some people, that feels very different.
