Tea Versus Coffee Caffeine: The Core Answer
Across typical servings, brewed coffee carries more caffeine than most tea. The gap comes from bean-to-water ratios and extraction. An 8–12 oz mug of drip coffee often lands between 95 and 200 mg, while a comparable cup of black tea sits near 25–60 mg. Matcha is the outlier because you drink the leaf itself; with 2–4 g of powder, a serving can range from about 40 up to 176 mg. That’s where some tea pours can edge past a small, mild coffee.
How you brew changes the math. Longer steeps, higher water temps, and larger serving sizes push tea upward. Coffee strength swings with grind size, brew ratio, and method. An espresso shot packs about 60–75 mg in 1 oz, while a large filter coffee can more than double that.
Typical Ranges You Can Count On
The table below shows broad ranges you’ll see at home and in cafés. Values reflect public health references and lab measurements, so treat them as a map, not a promise from every cup.
| Beverage (Serving) | Caffeine (mg) | Notes |
|---|---|---|
| Brewed coffee, 8–12 oz | 95–200 | Method and ratio drive the spread |
| Espresso, 1 oz shot | 60–75 | Highly concentrated; small volume |
| Cold brew, 12–16 oz | 150–300 | Often stronger due to long steep |
| Black tea, 8 oz | 25–60 | Steep time and blend matter |
| Green tea, 8 oz | 20–45 | Usually lower than black tea |
| Matcha, 8–12 oz (2–4 g) | 40–176 | Powder dose sets the range |
| Decaf coffee, 8 oz | 2–7 | Not zero; process leaves traces |
| Herbal “tea”, 8 oz | 0 | Not from Camellia sinensis |
If you compare sip for sip, coffee wins on average. That said, matcha doses can overlap with smaller filter coffees. Curious about brew specifics and cup sizes? Our write-up on caffeine in coffee breaks down typical mugs.
Which Tea Has More Caffeine Than Coffee? Real-World Benchmarks
Two cases show up often. First, a café matcha latte built with 3–4 g of powder in a 12 oz cup. That lands around 60–176 mg. Second, a strong breakfast tea steeped 5 minutes or longer, poured into a large mug. That can creep above 60 mg and, in big mugs, nudge toward triple digits. If the coffee next to it is a light 8 oz home brew, the tea can match or beat it.
Matcha: Why The Powder Punches Above Its Weight
Matcha uses ground leaf, so you consume the solids rather than a water extract. That multiplies caffeine delivery per gram. Dose rules the cup: a level teaspoon sits near 2 g; a heaping teaspoon can reach 3–4 g. Many café recipes use the higher end to keep color and taste vivid through milk and ice, which pushes caffeine toward the top of the range.
Black Tea: Blend, Leaf Grade, And Steep Time
Breakfast blends and CTC (crush-tear-curl) styles extract fast. Broken leaves present more surface area than whole leaf. Near-boiling water and a 4–5 minute steep pull more caffeine than a quick dunk. Large diner mugs amplify the dose even if the taste seems similar.
What Changes Caffeine In Your Cup
Three levers explain most variation: dose, contact time, and water temperature. Dose is the amount of grounds or tea you start with. Contact time is how long hot water stays in touch with them. Temperature sets extraction speed. Push any lever upward and you raise caffeine, up to a point.
Dose And Ratio
Brew ratios map dose to water. A common filter coffee ratio is 1:16 by weight. A typical loose-leaf tea sits near 2–3 g per 240 ml. Move either dose up and the milligrams follow.
Contact Time
Steep time is a slider. Tea gives up caffeine fast, then slows. Coffee extraction rises across the brew and levels off. Long steeps raise the number for both, with cold brew being the poster child for long soaks.
Temperature
Hotter water speeds extraction. Near-boiling water for black tea outpaces the cooler water often used for green tea. Espresso adds pressure, which squeezes a lot out in a short burst.
How Serving Size Flips The Winner
The label on the menu may say “cup,” yet volumes swing wide. An 8 oz pour can sit beside a 16 oz to-go mug. That alone can double caffeine. The same applies to matcha bowls, which run from small traditional servings to big iced lattes. Always check the ounces and the dose.
| Variable | Tea Effect | Coffee Effect |
|---|---|---|
| Dose (leaf/grounds) | More grams raise caffeine fast | Higher grams per liter lift caffeine |
| Time in contact | Longer steeps pull more early | Longer brews raise extraction |
| Water temperature | Hotter water extracts more | Near-boil water speeds pull |
| Serving volume | Bigger mugs multiply milligrams | Larger cups multiply milligrams |
| Leaf/bean form | Powdered matcha is concentrated | Espresso concentrates in less water |
Tea Versus Coffee: Feel And Timing
L-theanine in tea pairs with caffeine and many drinkers report a smoother lift. Coffee often brings a quicker rise because doses run higher. Sensitivity varies, so start small if sleep is a concern. Many people rest better when they stop caffeine later in the day, and general guidance keeps daily intake under ~400 mg for healthy adults.
Brewing Moves If You Want More Or Less
If You Want Tea To Beat Coffee
Pick matcha and use 3–4 g per 10–12 oz. Whisk with hot water, then add milk if you like. For leaf tea, choose a strong breakfast blend, steep 5 minutes in near-boiling water, and pour into a 12–16 oz mug. Both paths can rival a light home coffee.
If You Want To Keep Tea Mild
Pick whole-leaf green or white, steep 1–2 minutes below boiling, and cap cups at 8–10 oz. Shorter, cooler steeps drop the number while keeping taste clean.
If You Want Coffee With Less Punch
Choose a smaller cup, reduce brew ratio slightly, or mix in half decaf. Cold brew concentrates are strong by default; if you buy them, cut with extra water or ice.
Numbers From Trusted Sources
Public health pages list wide ranges because real cups vary. Official ranges for brewed coffee and tea appear in the FDA’s consumer update on caffeine. Matcha ranges come from university and medical write-ups that summarize common serving sizes and lab measurements. Brewed tea studies also report spans that reflect leaf grade and steep time.
Quick Decision Guide
Need a reliable caffeine boost in one cup? Go with brewed coffee. Want a tea that can rival a small coffee? Choose a generous matcha dose or a strong breakfast tea in a large mug. If sleep or jitters are an issue, aim for smaller pours and stop earlier in the day. Want more background? See coffee vs tea health effects.
