The caffeine in your latte comes mainly from its espresso: how much coffee is used, which beans are brewed and how much of the extraction goes into your cup. Adding more plain milk makes the drink milder, but does not remove caffeine. To estimate your latte’s caffeine, start with the espresso recipe rather than the size of the mug.
There is no single caffeine value that fits every European café or home setup. A latte made with one small espresso and a latte containing a complete double-basket extraction can look similar once milk is added. The useful question is: how much espresso actually went into this drink?
How Much Caffeine Is in a Latte?
For a published reference point, the European Food Safety Authority lists approximately 80 mg of caffeine in a 60 ml espresso serving. A plain latte made with that serving would contain approximately the same amount. EFSA stresses that caffeine content and portion sizes vary, so this is a reference example, not a measurement of your latte.
It also does not establish a fixed value for a “single” or “double”. Those labels are only useful when you know the recipe behind them. Do not assume every 30 ml shot contains half the caffeine of EFSA’s example, or that every double contains exactly twice a standard number.
| Latte preparation | What it tells you about caffeine | What to check |
|---|---|---|
| One espresso serving plus plain milk | The latte contains approximately the caffeine in that espresso serving. | The café’s published caffeine information or actual espresso recipe. |
| A complete double-basket extraction plus milk | All the caffeine extracted into that serving goes into the latte. | The coffee dose, beans and whether the entire extraction is used. |
| Half of one extraction, divided between two drinks | Each drink receives roughly half if the extraction is evenly shared. | Whether “one shot” means half of a shared extraction. |
| The same espresso in a larger cup with more milk | Total caffeine stays approximately the same. | Whether the larger size also includes extra espresso. |
| Decaf espresso plus milk | Usually substantially less caffeine, but not necessarily none. | Information supplied for the decaf coffee and serving. |
Why Shot Counts Can Be Misleading
At one café, a single may come from a dedicated single basket. Elsewhere, it may mean one side of a double-spouted portafilter. A home barista may call the entire output from an 18 g basket “one shot” because it comes from one brewing cycle. These descriptions do not identify the same amount of coffee.
Two spouts do not mean two complete double espressos
Suppose you brew 18 g of coffee and collect 36 g of espresso. If all 36 g goes into one latte, that drink receives the complete extraction. If you divide it evenly between two cups, each latte receives approximately half.
For the most even division, collect the espresso in one vessel, stir it and then divide it by weight. Two spouts may not deliver identical amounts. This example explains how one extraction is shared; it does not assign a caffeine value to an 18 g recipe.
When ordering, ask: “Does this latte use the whole double espresso, or one half?” That can be more informative than asking only how many shots it contains.
Does a Larger Latte Have More Caffeine?
Only if its ingredients supply more caffeine. If a 200 ml latte and a 300 ml latte use the same espresso base, with plain milk making up the difference, they contain approximately the same total caffeine. The larger drink has less caffeine per millilitre and a gentler coffee flavour.
A larger café size may include another espresso, however. Check the recipe before assuming that “large” means either more caffeine or simply more milk.
This also explains why a small flat white can taste stronger than a latte without containing more caffeine. The balance of espresso, milk and foam changes what you taste, even when the espresso base stays the same.
What Else Changes the Caffeine in Your Espresso?
The beans and dry coffee dose
Changing beans can change caffeine content even if the dose and yield stay constant. Increasing the amount of the same coffee generally increases the caffeine available for extraction, although the amount reaching the cup also depends on brewing conditions.
Keep the bean name and dose in your recipe notes. “Two shots” alone is a weak reference when you switch coffees, baskets or cafés.
The extraction recipe
Beverage yield, grind and brewing conditions affect extraction. A shorter espresso is more concentrated, but that does not automatically mean it contains more total caffeine. Equally, doubling the beverage yield does not reliably double the caffeine.
The relationship between ristretto, espresso and lungo caffeine is useful when choosing a flavour profile. It is less useful as a precise way to control caffeine intake. Pulling a shot shorter should not be treated as a guaranteed reduction.
Other ingredients
Plain dairy milk and ordinary unflavoured oat or soya drinks do not supply the coffee’s caffeine. Cocoa, chocolate, matcha or an added coffee concentrate can contribute more. Once those are included, count the whole recipe rather than just the espresso.
How to Keep Track of a Homemade Latte
With a Meraki espresso machine, make the espresso recipe your reference before adjusting the milk. Keep a short record:
- Coffee: the exact beans, including whether they are regular, decaf or a blend.
- Dry dose: the ground coffee used, in grams.
- Espresso yield: the beverage collected, in grams.
- Portion used: all of the extraction or a measured share.
- Extras: any other ingredients that contain caffeine.
These details help you repeat and compare drinks. They do not measure caffeine: neither shot time, beverage weight nor a machine display provides a laboratory caffeine result.
If a café or supplier provides caffeine data for a matching preparation, use that as your starting estimate. For example, if a specified espresso serving contains 100 mg, using the whole serving contributes approximately 100 mg to the latte; dividing it evenly contributes approximately 50 mg to each drink. These numbers demonstrate the calculation and are not universal espresso values.
How to Make a Latte With Less Caffeine
The most direct change is to replace some or all of the regular coffee with decaf. You can also use a measured portion of the finished espresso and save the remainder for another drink. Adding extra milk alone will not reduce the caffeine already in the cup.
A half-caf blend can be a useful middle ground, but equal weights of regular and decaf beans do not guarantee exactly half the caffeine. The coffees differ, and decaf can retain some caffeine. Adjust the recipe for taste when brewing decaf espresso at home, rather than assuming your regular grind setting will suit it.
To preserve a familiar milk-to-coffee balance when using less espresso, try a smaller finished drink. You may prefer that to keeping the same large cup and losing much of the coffee flavour.
Put Your Latte in the Context of the Whole Day
The German Federal Institute for Risk Assessment’s guidance on caffeine intake, drawing on EFSA’s assessment, identifies up to 200 mg in a single dose and up to 400 mg spread throughout the day as amounts that do not raise safety concerns for generally healthy adults. During pregnancy, the corresponding daily amount is up to 200 mg from all sources. These are assessment reference levels, not intake targets or personalised advice.
Include tea, chocolate, cola and other caffeine sources when considering your total. Timing matters too: a French clinical study of coffee after dinner found that a 90 mg caffeinated coffee disrupted sleep compared with decaf in participants who considered themselves caffeine-sensitive. A daily total alone does not tell you how a late latte will affect your sleep.
Frequently Asked Questions
How much caffeine is in a double-shot latte?
It depends on what the café or recipe calls a double. Use published information for that drink when available. Without it, the coffee dose, beans and amount of espresso used are more informative than the label alone.
Does milk reduce caffeine in a latte?
Milk dilutes caffeine across a larger drink but does not remove it. The total stays approximately the same when the espresso portion stays the same.
Does an iced latte contain more caffeine than a hot latte?
Not inherently. With the same espresso and no additional caffeine-containing ingredients, the total is approximately the same. Ice and milk change dilution and temperature.
Is a decaf latte caffeine-free?
Not necessarily. Decaf coffee can retain caffeine, and the amount depends on the coffee and preparation. Check supplier information if you need to manage intake closely.
Can I estimate caffeine from espresso weight?
Weight helps you repeat a recipe or divide one extraction, but it cannot identify caffeine content on its own. Different coffees and brewing recipes can produce the same beverage weight with different caffeine amounts.
