Does Tea Have More Caffeine Than Coffee? | Cup By Cup Truth

No, a standard cup of brewed coffee usually has more caffeine than a standard cup of black or green tea.

If you drink both, the short take is simple: coffee usually hits harder per cup. Still, that doesn’t mean tea is always the lighter pick. The gap can shrink, and some teas can edge past weak coffee.

That’s why this topic trips people up. “Tea” can mean green, black, matcha, bottled tea, or a long-steeped mug made with two bags. “Coffee” can mean a mild home brew, a dark café pour, or a tiny espresso-based drink that feels stronger than it is.

So the best answer is not tea versus coffee as broad labels. It’s cup versus cup, brew versus brew, and dose versus dose. Once you line it up that way, the pattern gets much easier to read.

Does Tea Have More Caffeine Than Coffee? What Usually Wins

In most side-by-side home servings, coffee comes out on top. The U.S. Food and Drug Administration lists typical caffeine in a 12-fluid-ounce brewed coffee at 113 to 247 milligrams, compared with 71 milligrams for black tea and 37 milligrams for green tea. That puts regular brewed coffee ahead in the usual matchup.

That said, “usually” matters. A weak coffee can land lower than a strong black tea. A large mug of tea made with extra leaves or bags can also climb fast. So the cleanest rule is this: coffee tends to carry more caffeine per serving, but your actual cup can break the pattern.

This is also why people get mixed signals from their own bodies. One person’s afternoon tea feels mild. Another person’s large breakfast mug feels close to coffee. The drink name tells part of the story. The serving and brewing style tell the rest.

Why The Numbers Change So Much

Tea Is Not One Drink

Black tea, green tea, oolong, matcha, and bottled tea drinks do not land in the same range. Tea caffeine shifts with leaf type, leaf amount, water heat, steep time, and cup size. Two bags in a large mug will not act like one bag in a small cup.

Matcha is its own case because you drink the powdered leaf, not just an infusion. That can push the caffeine count above many standard teas. Bottled teas can swing too, since recipes and serving sizes vary by brand.

Coffee Swings Even More Than Many People Think

Coffee beans, roast style, grind size, brew ratio, and serving size all change the total. A light breakfast brew may feel softer than a bold café pour. Then there is volume: a huge mug carries more caffeine than a small one even when the brew strength looks similar.

Espresso adds one more layer. Ounce for ounce it is strong, yet a single shot is small. A full mug of drip coffee often beats one shot on total caffeine.

Tea Vs Coffee Caffeine By Cup Size And Brew Style

The table below keeps the comparison grounded in common drink types. These are typical patterns, not fixed rules for every brand or brew.

Drink	Common Serving	Typical Caffeine
Green tea	12 fl oz	37 mg
Black tea	12 fl oz	71 mg
Brewed coffee	12 fl oz	113–247 mg
Weak black tea	8–12 fl oz	Low to moderate
Strong black tea, long steep	12–16 fl oz	Moderate to high
Matcha	1 prepared cup	Moderate to high
Weak drip coffee	8–12 fl oz	Moderate
Strong café drip coffee	12–16 fl oz	High

When Tea Can Beat Coffee

Tea does not usually out-caffeinate coffee, yet there are a few real-world cases where it can happen.

• A large mug of black tea made with two bags can outpace a weak small coffee.
• Matcha can land above many plain teas and some lighter coffee servings.
• Ready-to-drink tea products can surprise you if the bottle size is large.
• Refills matter. Two teas in an hour may outdo one coffee.

This matters most if you are trying to trim intake without feeling deprived. Swapping coffee for tea can cut caffeine, though not by the same amount every time. A strong tea habit can still stack up over a day.

What A “Stronger” Feeling Can Mean

People often say tea feels smoother and coffee feels sharper. That can be true for many drinkers, but the sensation is not just about the caffeine number. Sip speed, food intake, brew strength, and your own sensitivity all shape the effect.

Tea also tends to be sipped more slowly. Coffee is often taken faster, especially in the morning. That alone can change how the lift feels. So “coffee feels stronger” may reflect the drinking pattern as much as the label on the mug.

If caffeine tends to bother you, common signs can include restlessness, shakiness, insomnia, headache, dizziness, anxiety, or a fast heart rate. MedlinePlus on caffeine lays out those effects in plain language.

If You Want	Better Pick	Why
A bigger caffeine lift	Brewed coffee	It usually carries more caffeine per cup
A lighter afternoon drink	Green tea	It often lands well below regular coffee
A middle ground	Black tea	It sits between green tea and coffee in many cases
Lower intake without quitting caffeine	Tea in a smaller mug	It trims the dose and keeps the habit
More control	Home-brewed tea or coffee	You can change leaf amount, grounds, and cup size

How To Choose The Right Drink For Your Day

Pick Coffee If You Need More Lift Per Cup

Coffee is the better fit when you want more caffeine in one serving. It is also easier to overshoot with coffee, especially with large mugs and café drinks. If you get jittery, the fix may be smaller portions rather than cutting it out all at once.

Pick Tea If You Want More Room To Titrate

Tea can be easier to dial up or down. One bag, shorter steep, and a smaller cup keep the dose modest. Want more? Use a larger mug or a stronger tea. That flexibility is one reason many people shift to tea later in the day.

Watch The Clock, Not Just The Cup

A moderate dose late in the day can hit harder than a larger dose early in the morning if sleep is your weak spot. If your evenings feel wired, the problem may be timing more than total intake. Many people do better when coffee stays in the early part of the day and tea takes over later.

A Simple Rule That Works For Most People

If you want the safest everyday shortcut, assume coffee has more caffeine than tea unless you have a reason to think your tea is unusually strong or your coffee is unusually weak. That gets you the right answer most of the time without overthinking every cup.

Then fine-tune from there. Check serving size. Notice how long the tea steeped. Pay attention to how you feel after each drink. That practical pattern tells you more than broad drink labels ever will.
