11 teas + coffee · USDA + FDA sourced

Quick Answer

Per typical 8 oz serving, tea caffeine breaks down as: herbal 0 mg, hojicha 5 to 10 mg, kukicha 5 to 10 mg, white 6 to 55 mg, sencha 25 to 45 mg, gyokuro 30 to 50 mg, oolong 30 to 50 mg, black 47 to 90 mg, and matcha 38 to 88 mg (per 2 g whisk). Drip coffee delivers 95 to 200 mg, espresso 63 to 75 mg per 1 oz shot. Sources: USDA FoodData Central, FDA caffeine guidance, and peer-reviewed quantification studies.

Matcha vs Coffee, Side by Side

The juxtaposition, if that's all you came for. Numbers per typical serving, all sourced.

Matcha

2 g whisk · 6 oz water

Caffeine
38 to 88 mg
L-Theanine YESHigh, in the whole leaf
Energy curve Smooth, 3 to 6 hoursGradual climb, no crash
Antioxidants EGCG (high)Catechins, whole-leaf
Acidity (pH) ~9 (alkaline)Gentle on the stomach
Calories ~5 kcalPer whisk, unsweetened

Coffee

8 oz drip · standard brew

Caffeine
95 to 200 mg
L-Theanine NOAbsent in the bean
Energy curve Sharp peak, 30 to 90 minSpike then drop
Antioxidants Chlorogenic acidDifferent class than tea
Acidity (pH) ~5 (acidic)Can irritate sensitive stomachs
Calories ~2 kcalPer 8 oz, black
Bottom line: Coffee delivers more raw caffeine. Matcha delivers less caffeine plus L-theanine, which is why the energy feels longer and calmer. Both are real options. Pick by the curve you want, not just the milligram count.

8 oz

Daily caffeine intake

126 mg

That's 32% of the FDA daily safe limit (400 mg). Roughly the same as 1 cup of drip coffee.

Christian, founder of One with Tea: The number on a chart is one thing. The feel of a tea is another. Matcha caffeine sits right between sencha and black tea, but because it carries L-theanine in the leaf, the energy hits differently. Smoother climb, longer hold, no afternoon crash. That's the cup I built One with Tea around.

Three Things That Change Your Caffeine

The values above assume a typical brew. Push these levers and the number moves.

Water temperature

Hotter water pulls more caffeine. Sencha brewed at 80°C extracts roughly 60% of what 95°C extracts. Most premium Japanese green teas are designed for 70 to 80°C precisely to keep caffeine balanced with sweetness.

Steep time

Caffeine releases fast in the first 60 seconds, then plateaus. A 30-second sencha steep extracts roughly half the caffeine of a 3-minute steep. Same leaf, very different cup.

Leaf-to-water ratio

Doubling the leaf nearly doubles the caffeine. This is why matcha (whole-leaf, 2 g per cup) lands so much higher than steeped sencha (3 g leaf, but you drink the infusion, not the leaf itself).

Frequently Asked Questions

Which tea has the most caffeine?

By cup, black tea (47 to 90 mg per 8 oz) and matcha (38 to 88 mg per 2 g serving) lead. Gyokuro and oolong sit in the 30 to 50 mg range. Of the steeped Japanese greens, gyokuro is highest because the shading boosts free-amino-acid and caffeine concentration in the leaf. Source: USDA FoodData Central + peer-reviewed quantification.

Does matcha have more caffeine than coffee?

No. A typical matcha serving (2 g, 38 to 88 mg caffeine) sits well below an 8 oz drip coffee (95 to 200 mg). Matcha can match or beat a single espresso shot (63 to 75 mg). The difference matcha drinkers feel is not raw caffeine, it's the L-theanine in the leaf that smooths the absorption curve. Source: USDA + PMC peer-reviewed studies.

Can I drink hojicha at night?

Yes, for most people. Hojicha contains only 5 to 10 mg of caffeine per 8 oz cup, roughly 5 to 10% of a coffee, because the roasting process breaks down most of the caffeine in the bancha base leaf. Kukicha (twig tea) sits at a similar level. Caffeine sensitivity varies, but these are the lowest-caffeine true teas.

How much caffeine is safe per day?

The FDA cites 400 mg per day as the level not associated with negative effects for healthy adults. That's roughly 4 to 5 cups of drip coffee, 8 to 10 cups of black tea, or 6 to 10 servings of matcha. Pregnancy guidance from ACOG is lower at 200 mg per day. Source: FDA caffeine guidance.

Why does matcha caffeine feel different from coffee caffeine?

Matcha contains L-theanine, an amino acid that crosses the blood-brain barrier and modulates how caffeine is absorbed. The 2008 Haskell-Ramsay study and follow-ups document a calmer, longer-arc energy curve with caffeine + L-theanine versus caffeine alone. Coffee delivers caffeine without L-theanine, so the absorption spike is sharper. Source: PubMed 18006208 (Biological Psychology, 2008).

How does water temperature change tea caffeine?

Hotter water extracts more caffeine. Sencha brewed at 95°C delivers roughly 1.6× the caffeine of the same leaf at 80°C. This is why premium Japanese greens are designed for 70 to 80°C, keeping caffeine balanced and protecting the sweet umami notes that high heat destroys.
