How Much Caffeine Is in Your Coffee? Espresso, Filter & Co Compared
Here is a fun coffee paradox: the drink that looks the strongest is rarely the one with the most caffeine. A single espresso typically contains around 60–80 mg of caffeine – a large mug of filter coffee often carries more. Size and intensity of taste tell you surprisingly little.
So let's sort it out properly: how much caffeine is in each classic drink, what changes the numbers, and how much is considered fine per day. One note up front: this is general orientation, not medical advice – individual sensitivity varies a lot.

The Short Answer
Caffeine content depends on one thing above all: how much coffee actually went into the drink – not how big or how bitter it is. A latte made with one espresso shot has the same caffeine as that single espresso, just stretched with milk. A flat white with a double shot beats both.
That is the key mental model. Milk dilutes taste, not caffeine. Water dilutes taste, not caffeine. If you want to know how awake a drink will make you, count the shots – or, for filter methods, the brewing time and amount of grounds.
Caffeine by Drink: The Comparison Table
Typical values – every café and every bean is slightly different:
| Drink | Typical caffeine | Why |
|---|---|---|
| Espresso (single) | ~60–80 mg | Small but concentrated |
| Doppio / Flat White | ~120–160 mg | Two shots |
| Cappuccino / Latte (1 shot) | ~60–80 mg | Same shot, more milk |
| Americano (1–2 shots) | ~60–160 mg | Shots plus hot water |
| Filter coffee (200 ml) | ~80–120 mg | Long contact time extracts more |
| Cold brew (200 ml) | often 100 mg+ | Very long steeping, often strong concentrate |
| Matcha (per serving) | ~60–70 mg | Roughly espresso territory |
| Decaf | ~2–5 mg | Not zero, but close |
| Babyccino | 0 mg | Just frothed milk – that's the point |

What Changes the Numbers
The bean. Robusta beans typically contain roughly twice the caffeine of Arabica. Most specialty coffee is Arabica; many classic Italian espresso blends mix in Robusta – which is why that small bar espresso can hit harder than expected.
The brewing time. The longer water and grounds stay in contact, the more caffeine is extracted. That is why filter coffee and especially cold brew – steeped for 12 hours or more – often outrank a quick 25-second espresso, and why our cold brew recipe deserves a little respect.
The serving size. Obvious but often forgotten: a 400 ml mug of filter coffee is simply two 200 ml servings. The per-millilitre value matters less than what actually ends up in your cup.
How Much Is Too Much?
The European Food Safety Authority (EFSA) considers up to around 400 mg of caffeine per day – and up to about 200 mg in a single sitting – safe for most healthy adults. During pregnancy, the guideline drops to around 200 mg per day.
In everyday terms: three to four coffee drinks spread across the day keep most people comfortably inside that range. Individual sensitivity varies a lot, though – some people sleep fine after an evening espresso, others feel a 2 p.m. cappuccino at midnight. If you have health conditions or are pregnant, your doctor's guidance comes first.
And remember from our hydration guide: coffee counts towards your fluid intake – the "coffee dehydrates you" story is a myth.
Timing: When to Drink Your Last Cup
Caffeine stays in your system for several hours – the often-cited half-life is in the range of about five hours, varying from person to person. A practical rule of thumb many people do well with: last regular coffee in the early afternoon, and switch to decaf, a gentler matcha or tea after that.
The nice side effect of a cut-off time: the afternoon cup becomes a deliberate ritual instead of an autopilot refill – and the insulated HEY SAHNI Cup means the morning brew is still genuinely hot when you get to it.
FAQ
Does a latte have less caffeine than an espresso?
No – a latte made with one shot contains the same caffeine as that single espresso. Milk dilutes the taste, not the caffeine. Only the number of shots changes the math.
Is cold brew stronger than espresso?
Per serving, often yes. The very long steeping time extracts a lot of caffeine, and cold brew is frequently drunk in larger portions. Per millilitre, espresso is more concentrated – but nobody drinks 200 ml of espresso.
Is decaf completely caffeine-free?
No – decaffeination removes most but not all caffeine. A cup of decaf typically still contains around 2–5 mg, compared to 60–80 mg in a regular espresso. For almost everyone, that difference is negligible.
When should I stop drinking coffee before bed?
Caffeine lingers for several hours, so many people do best with their last regular cup in the early afternoon. Individual sensitivity varies – if your sleep is light, move the cut-off earlier and switch to decaf or tea.
