How much caffeine is in a cup of coffee?


How much caffeine is in one cup of coffee?

A standard cup of filter coffee (125 ml) contains roughly 85 mg of caffeine on average. But that number shifts dramatically depending on brew method, bean variety, grind size, and water contact time. The 50 to 150 mg range you'll see cited across sources isn't vague science. It's a genuine reflection of how variable coffee actually is.

At Matubu Coffee, we see this directly when customers come to us trying to manage their intake. Someone switching from a large French press to a short espresso assumes they're cutting caffeine in half. In practice, they often aren't, because a double espresso at a café can easily deliver 120 mg in 60 ml. The serving size illusion is one of the most common misunderstandings we encounter.

Here's a practical breakdown by brew method:

  • Filter coffee (125 ml): approximately 85 mg
  • Espresso (30 ml): approximately 60 to 80 mg per shot
  • Instant coffee (125 ml): approximately 60 mg
  • Cold brew (240 ml): 150 to 240 mg, the highest of any common format
  • Decaf coffee (125 ml): 2 to 5 mg, not zero, but close

Cold brew deserves particular attention. Because it uses a long extraction time (often 12 to 24 hours), the total caffeine pulled from the grounds is significantly higher than a standard drip brew. If you're monitoring your intake carefully, cold brew is the format to watch.


How does bean variety affect caffeine levels?

Bean variety is a factor most people overlook entirely. Robusta beans contain roughly twice the caffeine of Arabica. Many supermarket blends and cheaper espresso products lean on Robusta for its cost and crema, which means the caffeine load in an unremarkable office espresso can be considerably higher than a carefully sourced specialty cup.

All of Matubu's single-origin coffees and specialty blends are Arabica-forward, which means lower baseline caffeine alongside a cleaner, more nuanced flavour profile. That's not just a taste preference — for anyone monitoring their caffeine intake, it's a meaningful practical difference. You can browse our full specialty coffee selection to see exactly where each origin comes from.

Altitude also plays a role. Beans grown at higher elevations mature more slowly, which generally correlates with lower caffeine content and more complex sugars. Our Colombia Caldas Decaf, for instance, is grown at 1,600 to 1,950 metres on volcanic soils in the Eje Cafetero zone — before decaffeination even enters the picture, this is already a naturally gentle bean.


How much caffeine is too much?

The European Food Safety Authority (EFSA) sets the safe upper limit for healthy adults at 400 mg of caffeine per day. That translates to roughly four to five standard cups of filter coffee, or about five single espresso shots.

But "safe" and "optimal for your body" are different thresholds. For people who experience anxiety, disrupted sleep, or heart palpitations, the personal limit is often well below 400 mg. If caffeine makes you feel wired rather than alert, the issue isn't willpower. It's that your body processes caffeine more slowly than average, a trait linked to specific variants in the CYP1A2 gene, which affects caffeine metabolism.

The practical implication: 200 mg of caffeine is not a lot for a fast metaboliser, but it can be genuinely disruptive for a slow one. Two cups of filter coffee puts most people in the 150 to 200 mg range for the day, which sits comfortably within EFSA's guidance, but that assumes standard serving sizes and no additional caffeine from tea, soft drinks, or chocolate.

How does coffee caffeine compare to tea?

Tea is consistently lower in caffeine than coffee, which is part of why so many wellness-focused drinkers make the switch. According to the Voedingscentrum (Dutch Nutrition Centre), a 125 ml cup of black tea contains around 30 mg of caffeine, and green tea sits at approximately 20 mg per cup.

That's roughly one-third to one-quarter of what a comparable cup of filter coffee delivers. For anyone wanting a warm morning ritual without the caffeine spike, a high-quality loose-leaf green or black tea is a genuinely effective step down, not a compromise.

For those who want to eliminate caffeine entirely from their hot drinks, herbal infusions are the cleanest option. Rooibos, rosehip, and chamomile contain no caffeine whatsoever. The difference between a good herbal infusion and a supermarket teabag is real — the flavour complexity, the ingredient quality, and the absence of artificial additives are all things worth paying attention to when you're reading labels carefully.


What's the best option if you want to cut back on coffee caffeine?

The best approach depends on what you're actually trying to protect: the ritual, the flavour, or just the warmth of a hot drink in the morning.

If the flavour of coffee is what you love, specialty decaf is the most direct answer. Our Colombia Caldas Decaf processed with sugarcane-derived ethyl acetate delivers 2 to 5 mg of caffeine per cup — effectively trace amounts — while preserving the full flavour profile: milk chocolate, brown sugar, nougat, dried fruit, and a hint of cola. The decaffeination happens locally in Colombia using a natural sugarcane byproduct process, which keeps the ecological footprint low and avoids the chemical solvents used in older industrial methods.

This matters for clean-label buyers. The EA (ethyl acetate) method derived from sugarcane is a naturally occurring compound. It's not a synthetic additive, and it leaves no residue in the finished coffee. The result is a cup that tastes like specialty coffee because it is specialty coffee, just without the caffeine.

It's available in 200g, whole bean or ground for any brew method — espresso, French press, filter, AeroPress, or moka pot. A subscription option brings the price down by 10%, with delivery every 4, 8, or 12 weeks. If you're experimenting with brew methods alongside your decaf switch, our comparison of V60, AeroPress, and French Press is worth reading before you commit to a grind.

If the ritual matters more than the coffee flavour specifically, the transition to a quality herbal infusion or a ceremonial-grade matcha (which does contain some caffeine, but releases it more slowly) gives you something to look forward to in the morning without the crash.


Closing

Knowing the actual caffeine numbers by brew method transforms vague intentions into specific, manageable choices — and the difference between a cold brew and a decaf specialty cup is not a small detail, it's a 200 mg swing. With that clarity, you can design a daily routine that keeps you within your personal threshold without giving up the sensory experience you actually enjoy. Start with our naturally decaffeinated Colombia Caldas, a specialty-grade cup with 2 to 5 mg of caffeine, available now in whole bean or your preferred grind.


Frequently asked questions

How much caffeine is in 1 cup of normal coffee?

A standard cup of filter coffee (125 ml) contains approximately 85 mg of caffeine on average. The actual amount varies based on brew method, grind size, and bean variety. Espresso delivers 60 to 80 mg in a 30 ml shot, while cold brew can contain 150 to 240 mg in a 240 ml serving. Robusta-based blends consistently run higher than Arabica-based coffees at equivalent serving sizes.

Is 200 mg of caffeine a lot?

For most healthy adults, 200 mg sits well within the European Food Safety Authority's recommended daily limit of 400 mg. Two standard cups of filter coffee put you in roughly that range. Whether it feels like a lot depends on your individual caffeine metabolism, which varies genetically. If 200 mg leaves you anxious or disrupts your sleep, your body likely processes caffeine more slowly than average — a sign to reduce intake, not push through.

Is 2 cups of coffee a lot of caffeine?

Two cups of filter coffee (125 ml each) delivers approximately 170 mg of caffeine, which is well within safe daily limits. If those cups are large (250 ml), that figure rises to around 240 mg. The format matters too: two double espressos at a café could deliver 240 mg or more. Tracking your actual serving sizes, not just the number of cups, gives you a more accurate picture of your daily intake.

How much caffeine is in decaf coffee?

Decaf coffee is not caffeine-free. It typically contains 2 to 5 mg per 125 ml cup. That's roughly 95 to 97% less caffeine than regular filter coffee. For most people, including those with caffeine sensitivity, this residual amount is negligible. Matubu Coffee's Colombia Caldas Decaf uses a natural sugarcane-based decaffeination process that preserves the full flavour profile while keeping caffeine at this trace level.

How does caffeine in coffee compare to caffeine in tea?

Filter coffee (125 ml) contains roughly 85 mg of caffeine on average, while black tea at the same volume contains around 30 mg and green tea approximately 20 mg. Herbal infusions such as rooibos, rosehip, and chamomile contain no caffeine at all. For anyone stepping down from coffee, black tea is a practical midpoint, and herbal infusions are the cleanest caffeine-free alternative.

What is the highest-caffeine coffee format?

Cold brew is the highest-caffeine common coffee format, delivering 150 to 240 mg per 240 ml serving due to its extended extraction time. Robusta-heavy espresso blends also run high. If you're managing your intake, cold brew and dark supermarket blends using Robusta beans are the formats to limit first. Switching to a single-origin Arabica specialty coffee or a quality decaf immediately reduces your daily caffeine load without requiring you to give up coffee entirely.
