How Much Caffeine Is in Matcha Green Tea Powder?

Most people want a quick answer  so let’s start there.
A serving of matcha green tea powder contains between 30mg and 70mg of caffeine per cup.

But here’s the twist:
Matcha gives you energy that feels completely different from coffee. No jitters. No crash. Just calm, steady focus. And that’s because the caffeine in matcha doesn’t act alone; it's paired with an amino acid called L-Theanine that changes the whole experience.

The caffeine in premium Japanese matcha works differently, giving you a calm, lasting focus instead of a quick spike and crash.

At Bree Matcha, we make it easy to choose a blend that supports that balance naturally, one that energizes, not overstimulates.

1. The Formula: Why Quality and Grade Dictate the Dose

The caffeine content in matcha isn’t fixed. It depends on a few key factors that affect every sip.

A. The Grade of Matcha

If you are looking for the best organic matcha powder or best quality matcha, you should always go for shade-grown japanese leaves which are stone ground into a fine, green powder which ensures dominance, quality and the power of matcha. 

B. The Serving Size

Caffeine levels rise with serving size.

• 1 gram (½ teaspoon) = ~35mg of caffeine

• 2 grams (1 teaspoon) = ~70mg of caffeine

So, a bigger scoop means more energy, but still smoother than a shot of espresso.

C. The Water Temperature and Whisking

To get the balance of flavor, aim for warm water and then vigorously start whisking the matcha; it will release more caffeine and antioxidants.

Choosing a high-quality organic Japanese matcha powder means you’re starting with leaves that already have the best caffeine-to-L-Theanine ratio nature can offer.

2. The Calm Energy Curve: L-Theanine’s Jitter-Free Guarantee

Matcha’s secret isn’t just caffeine; it's the balance.

The amino acid L-Theanine, found in abundance in shade-grown matcha, changes how your body absorbs caffeine. It slows down the release, giving you a steady rise of alertness instead of the sharp spike and crash that coffee causes.

L-Theanine also promotes alpha brain waves, the same state linked with meditation and calm focus.
That’s why matcha feels like “calm energy”  alert, yet centered.

Every cup of Bree Matcha is crafted from leaves rich in this natural amino acid, ensuring your daily ritual keeps you focused, calm, and clear.

3. The Comparison: Matcha vs. The Usual Suspects

Here’s how matcha caffeine compares to other common drinks:

Even with similar caffeine levels to coffee, matcha feels different, longer-lasting, smoother, and easier on the body.

4. Maximizing Your Bree Matcha Experience

You can control your energy just by adjusting how you make your matcha:

• For a stronger, longer lift: Use 2 scoops of the best organic matcha powder with slightly hotter water.

• For gentle, calm focus: Use 1 scoop and water just below boiling.
  

Both give you sustained clarity; it's just about matching your brew to your mood.

For the best results, always start with certified organic Japanese matcha, like Bree Matcha, made from carefully shade-grown and stone-ground leaves. You’ll get the cleanest, most balanced energy possible.
