One 1 fl oz single shot of espresso typically has 60-75 mg of caffeine. That’s less liquid than an 8 fl oz brewed coffee, but still a concentrated caffeine serving.
How Much Caffeine In One Shot Of Espresso: one 1 fl oz single shot typically has 60-75 mg of caffeine. That is the USDA/FDA reference range for a standard espresso serving.
For comparison, an 8 fl oz brewed coffee typically has 80-100 mg, while an 8 fl oz decaf coffee has 2-15 mg. Espresso is more concentrated by volume, but a single shot often has less total caffeine than a full cup of brewed coffee.
The Short Answer
One shot of espresso has about 60 to 75 mg of caffeine. That is for a typical 1 fl oz single shot. If you order a double espresso, use two shots: about 120 to 150 mg.
| Drink | Typical serving | Caffeine |
|---|---|---|
| Espresso | 1 fl oz single shot | 60-75 mg |
| Brewed coffee | 8 fl oz | 80-100 mg |
| Decaf coffee | 8 fl oz | 2-15 mg |
| Cold brew | 8 fl oz | 100-200 mg |
Espresso is stronger per ounce, but not always higher per drink
A 1 fl oz espresso shot is small, but concentrated: 60 to 75 mg in one ounce. An 8 fl oz brewed coffee has 80 to 100 mg total, spread across eight ounces.
Per ounce, espresso works out to 60 to 75 mg per fl oz. Brewed coffee works out to 10 to 12.5 mg per fl oz, using the listed 80 to 100 mg for an 8 fl oz serving.
That means espresso has about 6 times the caffeine per ounce of brewed coffee at the low end: 60 divided by 10. At the high end, 75 divided by 12.5 is also 6.
But per serving, one espresso shot usually has less caffeine than an 8 fl oz brewed coffee. The espresso has 60 to 75 mg; brewed coffee has 80 to 100 mg.
Common order math
Single espresso: 1 shot equals 60 to 75 mg caffeine.
Double espresso: 2 shots equal 120 to 150 mg caffeine. That is more than a typical 8 fl oz brewed coffee at 80 to 100 mg.
Triple espresso: 3 shots equal 180 to 225 mg caffeine. That is higher than the listed 8 fl oz cold brew range at the low end, but overlaps cold brew’s 100 to 200 mg range.
Four shots: 4 shots equal 240 to 300 mg caffeine. That is calculated directly from 60 to 75 mg per shot times four.
Espresso in milk drinks
A latte, cappuccino, macchiato, or flat white gets its caffeine from the espresso shots, not from the milk. If it has one shot, count 60 to 75 mg.
If the drink has two shots, count 120 to 150 mg. A larger cup does not automatically mean more caffeine unless it includes more espresso shots.
For example, a 12 fl oz latte with one shot has 60 to 75 mg. A smaller 6 fl oz cappuccino with two shots has 120 to 150 mg.
Quick comparisons
One espresso shot has more caffeine than 8 fl oz decaf coffee, which has 2 to 15 mg. Even the low espresso figure, 60 mg, is 4 times the high decaf figure of 15 mg.
One espresso shot has less caffeine than 8 fl oz cold brew in the listed range. Espresso is 60 to 75 mg; cold brew is 100 to 200 mg.
Compared with brewed coffee, one shot is lower in total caffeine. Two shots are higher: 120 to 150 mg for double espresso versus 80 to 100 mg for 8 fl oz brewed coffee.
Caffeine in one espresso shot
One single shot of espresso, 1 fl oz, typically contains 60 to 75 mg of caffeine. That is the number to use when estimating caffeine from a standard espresso shot.
The range matters because espresso is concentrated. A 1 fl oz shot can vary by coffee dose, grind, water contact, and recipe, but the practical estimate is still 60 to 75 mg per single shot.
| Espresso amount | Caffeine estimate |
|---|---|
| 1 single shot, 1 fl oz | 60 to 75 mg |
| 2 single shots, 2 fl oz total | 120 to 150 mg |
| 3 single shots, 3 fl oz total | 180 to 225 mg |
| 4 single shots, 4 fl oz total | 240 to 300 mg |
Single shot vs brewed coffee
A single espresso shot is smaller than a cup of coffee but not weaker. An 8 fl oz brewed coffee has 80 to 100 mg of caffeine, while a 1 fl oz espresso has 60 to 75 mg.
Worked example: 1 espresso shot at 60 to 75 mg is less caffeine than one 8 fl oz brewed coffee at 80 to 100 mg. But ounce for ounce, espresso is much more concentrated.
Per fluid ounce, espresso works out to 60 to 75 mg per fl oz. Brewed coffee, using 80 to 100 mg in 8 fl oz, works out to 10 to 12.5 mg per fl oz.
So espresso has about 6 times the caffeine concentration of brewed coffee by volume, using the low-end comparison: 60 divided by 10 equals 6.
What if the drink has more than one shot?
Many coffeehouse drinks contain more than one espresso shot. If the drink has 2 shots, double the estimate: 120 to 150 mg. If it has 3 shots, use 180 to 225 mg.
Example: a latte made with 1 shot has 60 to 75 mg. A latte made with 2 shots has 120 to 150 mg. The milk changes the drink size, not the espresso caffeine count.
Example: an iced espresso drink with 3 single shots contains about 180 to 225 mg from espresso before counting any other caffeine-containing add-ins.
Edge cases that change the estimate
If “one shot” means a single 1 fl oz espresso, use 60 to 75 mg. If a café calls a double shot “one drink shot,” the caffeine may be closer to 120 to 150 mg.
A short drink is not automatically low caffeine. A 2 fl oz double espresso can contain 120 to 150 mg, more than a typical 8 fl oz brewed coffee at 80 to 100 mg.
Decaf espresso is not covered by the reference figures here. For decaf coffee, the listed 8 fl oz range is 2 to 15 mg, but that figure is for decaf coffee, not a 1 fl oz espresso shot.
Cold brew is another edge case. An 8 fl oz cold brew has 100 to 200 mg, so it can exceed one single espresso shot even though espresso tastes stronger.
Quick comparison with common caffeine sources
| Item | Typical serving | Caffeine |
|---|---|---|
| Espresso | 1 fl oz single shot | 60 to 75 mg |
| Brewed coffee | 8 fl oz | 80 to 100 mg |
| Instant coffee | 8 fl oz | 30 to 90 mg |
| Black tea | 8 fl oz | 40 to 70 mg |
| Energy drink | 8 fl oz | 70 to 100 mg |
Bottom line for counting: use 60 to 75 mg caffeine per 1 fl oz espresso shot. Multiply by the number of single shots in the drink.
What counts as one shot
One shot of espresso counts as 1 fl oz, about 30 ml. In the USDA/FDA reference data, that 1 fl oz single shot typically contains 60 to 75 mg caffeine.
That means the word “shot” is a serving size, not a cup size. If a café pours espresso into a 3 oz demitasse, the serving may still be one shot if the espresso itself is about 1 fl oz.
Single, double, and split shots
| Order or pour | Espresso volume | Caffeine estimate |
|---|---|---|
| Single shot | 1 fl oz | 60-75 mg |
| Double shot | 2 fl oz | 120-150 mg |
| Half of a double shot | 1 fl oz | 60-75 mg |
| Two single shots | 2 fl oz total | 120-150 mg |
A double shot is not “stronger” because it has a different caffeine rule. It is simply two 1 fl oz shots together, so the caffeine estimate doubles from 60-75 mg to 120-150 mg.
Worked example: if your latte is made with 2 fl oz of espresso, count it as two shots. Estimated caffeine: 60-75 mg plus 60-75 mg, for a total of 120-150 mg.
Worked example: if an iced drink lists “3 shots,” count 3 fl oz of espresso. Estimated caffeine: 3 × 60-75 mg, or 180-225 mg.
What if the cup is larger than 1 fl oz?
The cup does not define the shot. A 12 fl oz latte with one espresso shot still counts as one shot, because the espresso portion is 1 fl oz. The milk and ice do not add espresso caffeine.
A 16 fl oz drink can have one, two, or more shots. Use the number of espresso shots, not the finished drink size, to estimate caffeine.
Example: a 16 fl oz latte with one shot has 60-75 mg. A 16 fl oz latte with two shots has 120-150 mg. Same cup size, different espresso count.
Edge cases: ristretto, lungo, and café wording
If a menu says “single espresso,” use the reference serving: 1 fl oz and 60-75 mg caffeine. If it says “double espresso,” use 2 fl oz and 120-150 mg.
If a shop uses the word “ristretto” or “lungo,” the liquid volume may be smaller or larger than 1 fl oz. Unless the shop gives caffeine data, the safe reference estimate is still based on shot count, not appearance.
If a machine dispenses a “single” button into two cups, each cup may hold half a shot. Half of the reference shot is 0.5 fl oz and roughly half the caffeine range: 30-37.5 mg.
If a recipe calls for “1 shot espresso” but measures by tablespoons, use 1 fl oz. Since 1 fl oz equals 2 tablespoons, the recipe is asking for about 2 tablespoons of espresso.
For caffeine math, the clean rule is: 1 shot = 1 fl oz espresso = 60-75 mg caffeine. Multiply that range by the number of shots in the drink.
Why caffeine amounts vary
One shot of espresso is listed as 1 fl oz and typically has 60-75 mg caffeine. The range exists because “one shot” describes drink volume, not a fixed caffeine dose.
That 15 mg spread matters. A low-end single shot at 60 mg is 20% lower than a high-end single shot at 75 mg. Two singles can therefore land at 120-150 mg.
Shot count changes the math fast
| Espresso order | Volume | Typical caffeine |
|---|---|---|
| Single shot | 1 fl oz | 60-75 mg |
| Double shot | 2 fl oz | 120-150 mg |
| Triple shot | 3 fl oz | 180-225 mg |
A latte, cappuccino, or Americano may taste milder than straight espresso, but dilution does not remove caffeine. If it contains one 1 fl oz shot, count 60-75 mg.
If the same drink is made with two shots, count 120-150 mg. The cup may be larger because of milk or water, but the caffeine follows the number of espresso shots.
Espresso is concentrated, not always the highest total
Per serving, espresso looks small: 1 fl oz for 60-75 mg. Brewed coffee is listed at 8 fl oz for 80-100 mg, so one mug can exceed one espresso shot in total caffeine.
Worked example: one 1 fl oz espresso at 60-75 mg has less total caffeine than one 8 fl oz brewed coffee at 80-100 mg. But espresso delivers it in one-eighth the liquid volume.
Cold brew is an edge case. An 8 fl oz serving is listed at 100-200 mg. That equals about 1.3 to 3.3 single espresso shots, using the 60-75 mg espresso range.
Instant coffee is another wide case: 8 fl oz can have 30-90 mg. Its high end can beat a 60 mg espresso shot, while its low end is only half of that low-end shot.
“Coffee drink” labels can hide the dose
A mocha, flat white, or iced latte does not reveal caffeine by cup size alone. The key question is whether it contains 1, 2, or 3 espresso shots.
Example: a 16 fl oz iced latte with one shot still tracks as 60-75 mg. A smaller 8 fl oz latte with two shots tracks as 120-150 mg.
Dark chocolate can add a small amount if the drink includes it. One ounce of dark chocolate is listed at 10-25 mg caffeine, separate from the espresso.
So a one-shot mocha with 1 oz dark chocolate can total about 70-100 mg: 60-75 mg from espresso plus 10-25 mg from chocolate.
Decaf espresso is not covered in the reference figures. For decaf coffee, the listed 8 fl oz range is 2-15 mg, but that figure should not be applied to a 1 fl oz espresso shot.
For a standard single espresso, the best numeric answer is 60-75 mg caffeine per 1 fl oz shot. Use shot count, not cup size, to estimate the drink.
How to check your cafe
Use the cafe’s actual pour size first. The reference point is simple: 1 fl oz single shot of espresso typically has 60-75 mg caffeine. If your cafe serves more or less than 1 fl oz, scale from that range.
Step-by-step check at the counter
- 1. Ask the shot size in fluid ounces. Say: “Is your single espresso 1 fl oz?” If yes, use 60-75 mg. If the cafe calls a 2 fl oz pour a “single,” estimate 120-150 mg unless they provide their own lab-tested number.
- 2. Count the number of shots, not the cup size. A 12 fl oz latte with 1 shot is still about 60-75 mg from espresso. A small cappuccino with 2 shots is about 120-150 mg, even if the cup is smaller.
- 3. Check whether “double” means 2 shots. In many cafes, a double espresso equals two 1 fl oz shots. Using the reference range, that is 120-150 mg caffeine. If the double is only 1 fl oz total, ask for the cafe’s posted figure.
- 4. Ask if extra shots are added by default. Some iced drinks and larger lattes may include more espresso. Example: a 16 fl oz iced latte with 3 shots is about 180-225 mg from espresso.
- 5. Watch for ristretto or long-pour edge cases. If the cafe changes the water volume but still uses one espresso shot as its basis, do not assume the caffeine is lower or higher from volume alone. Ask how many espresso shots were used.
- 6. Compare espresso with nearby menu choices. If the cafe cannot answer, use known ranges: brewed coffee is 80-100 mg per 8 fl oz, cold brew is 100-200 mg per 8 fl oz, and black tea is 40-70 mg per 8 fl oz.
Quick math examples
| Order | Espresso shots | Estimated caffeine |
|---|---|---|
| Single espresso | 1 shot | 60-75 mg |
| Double espresso | 2 shots | 120-150 mg |
| Latte with extra shot | 2 shots | 120-150 mg |
| Iced drink with 3 shots | 3 shots | 180-225 mg |
Worked example: if your cafe says its cappuccino has “two espresso shots,” multiply 60-75 mg by 2. Your caffeine estimate is 120-150 mg, even if the drink is only 6 fl oz.
Another example: a mocha may taste less strong because of milk and chocolate, but caffeine from espresso still follows the shot count. One espresso shot gives 60-75 mg before any chocolate is counted.
If dark chocolate is part of the drink, 1 oz typically adds 10-25 mg caffeine. Ask whether the cafe uses real chocolate, cocoa, or syrup if you need a tighter estimate.
Best cafe question: “How many 1 fl oz espresso shots are in this drink?” Once you have that number, multiply by 60-75 mg per shot.
Steps to compare espresso drinks
Use 60-75 mg caffeine for 1 fl oz single shot of espresso. That is the comparison unit. If the drink lists shots, multiply the shot count by 60-75 mg.
1. Count the espresso shots first
A 1-shot drink has about 60-75 mg caffeine. A 2-shot drink has about 120-150 mg. A 3-shot drink has about 180-225 mg. A 4-shot drink has about 240-300 mg.
| Espresso amount | Typical caffeine |
|---|---|
| 1 fl oz single shot | 60-75 mg |
| 2 shots | 120-150 mg |
| 3 shots | 180-225 mg |
| 4 shots | 240-300 mg |
2. Ignore cup size unless it changes the shot count
Milk, foam, ice, and water do not add caffeine. A 12 fl oz latte with 1 shot is still about 60-75 mg. A smaller 8 fl oz latte with 2 shots is about 120-150 mg.
This is the common mistake: comparing ounces of the finished drink instead of espresso shots. A larger cup can have less caffeine than a smaller cup if it has fewer shots.
3. Compare espresso to brewed coffee by serving
An 8 fl oz brewed coffee has about 80-100 mg caffeine. One 1 fl oz espresso shot has about 60-75 mg. So one espresso shot is usually less caffeine than one 8 fl oz brewed coffee.
Two espresso shots give 120-150 mg. That is more than an 8 fl oz brewed coffee at 80-100 mg. A double espresso crosses brewed coffee mainly because it doubles the espresso dose.
4. Work through common drink orders
A cappuccino with 1 shot: 60-75 mg. A cappuccino with 2 shots: 120-150 mg. The foam volume changes texture, not caffeine.
An Americano with 1 shot: 60-75 mg. An Americano with 2 shots: 120-150 mg. Added hot water stretches the drink but does not change the caffeine total.
A mocha with 1 espresso shot plus 1 oz dark chocolate can be about 70-100 mg total: 60-75 mg from espresso plus 10-25 mg from dark chocolate.
A mocha with 2 espresso shots plus 1 oz dark chocolate can be about 130-175 mg total: 120-150 mg from espresso plus 10-25 mg from dark chocolate.
5. Watch edge cases
- Single-shot large drink: still 60-75 mg if it contains only 1 espresso shot.
- Extra-shot drink: add 60-75 mg for each added 1 fl oz shot.
- Chocolate espresso drink: add 10-25 mg for each 1 oz dark chocolate portion.
- Decaf comparison: an 8 fl oz decaf coffee has 2-15 mg, far below a regular espresso shot.
- Cold brew comparison: 8 fl oz cold brew has 100-200 mg, which can exceed 1 or 2 espresso shots depending on the exact drink.
Fast rule: count espresso shots, multiply by 60-75 mg, then add caffeine from chocolate only if the drink contains it. Finished drink size is secondary.
Espresso versus drip coffee
A standard 1-ounce shot of espresso has about 63 milligrams of caffeine. An 8-ounce cup of brewed drip coffee has about 96 milligrams. So espresso is stronger per ounce, but drip coffee usually delivers more caffeine per serving.
Caffeine per ounce
Espresso: 63 milligrams in 1 fluid ounce equals 63 milligrams per ounce.
Drip coffee: 96 milligrams in 8 fluid ounces equals 12 milligrams per ounce.
That means espresso has about 5.25 times as much caffeine per ounce as drip coffee: 63 divided by 12 equals 5.25.
The key difference is serving size. Espresso is concentrated and small. Drip coffee is weaker per ounce, but the cup is much larger.
Worked examples
One 1-ounce espresso shot: 63 milligrams of caffeine.
One 2-ounce double espresso: 126 milligrams of caffeine, because 63 times 2 equals 126.
One 8-ounce drip coffee: 96 milligrams of caffeine.
One 12-ounce drip coffee: 144 milligrams of caffeine, using 12 milligrams per ounce. The math is 12 times 12 equals 144.
One 16-ounce drip coffee: 192 milligrams of caffeine. That is 12 milligrams per ounce times 16 ounces.
Compared with one espresso shot, an 8-ounce drip coffee has 33 more milligrams of caffeine: 96 minus 63 equals 33.
Compared with a double espresso, a 12-ounce drip coffee has 18 more milligrams: 144 minus 126 equals 18.
What this means when ordering
If you sip one shot of espresso, you get less total caffeine than in a typical 8-ounce mug of drip coffee.
If you order a double espresso, its caffeine is closer to a medium drip coffee. At 126 milligrams, it is below a 12-ounce drip coffee at 144 milligrams.
If you want less caffeine, a single espresso is often lower than a full cup of drip coffee. If you want more caffeine, cup size matters more than intensity.
Bottom line: espresso wins on concentration, while drip coffee often wins on total caffeine per serving.
Decaf espresso caffeine
Decaf espresso is not caffeine-free. In the U.S., decaf coffee generally means at least 97% of the caffeine has been removed before roasting, but a small amount remains in the beans.
A useful working range for one decaf espresso shot is 3 to 16 mg of caffeine. That range comes from lab testing of decaf espresso samples, where single shots measured from 3.0 mg to 15.8 mg.
For comparison, a regular 1 fl oz espresso is commonly listed at about 63 mg of caffeine. So a decaf shot at 3 mg has about 5% as much caffeine, while a 16 mg shot has about 25% as much.
Worked examples
If your café’s decaf espresso is 5 mg per shot, a decaf latte with 1 shot has 5 mg. A 2-shot decaf latte has 10 mg. A 3-shot decaf drink has 15 mg.
If the decaf espresso is at the high end, 16 mg per shot, a 2-shot decaf cappuccino has 32 mg. A 3-shot decaf Americano has 48 mg, which is no longer a tiny amount.
Using the regular espresso comparison, 2 regular shots at 63 mg each equal 126 mg. Two decaf shots at 3 to 16 mg each equal 6 to 32 mg.
Why the number varies
The caffeine in decaf espresso changes with the bean, decaffeination method, roast, grind, dose, water temperature, and shot yield. A larger or longer shot can extract more caffeine.
Drink size can be misleading. A 12 oz decaf latte may contain only 1 espresso shot, while a 16 oz decaf latte may contain 2 shots. The caffeine follows the shot count, not the cup size.
For caffeine-sensitive people, count decaf espresso as real caffeine. One shot is often low, but multiple decaf shots can reach 20 to 50 mg depending on the café and recipe.
Best estimate for one decaf espresso shot: use 3 to 16 mg. For quick menu math, multiply that range by the number of shots in the drink.
Daily caffeine intake limits
For most healthy U.S. adults, the FDA cites 400 mg of caffeine per day as an amount not generally associated with dangerous, negative effects.
A standard 1 fl oz shot of espresso is commonly listed at about 63 mg of caffeine. Using that figure, 400 mg equals about 6.3 shots.
In practical terms, 6 shots would be about 378 mg. A 7th shot would raise the total to about 441 mg, which is above the FDA’s 400 mg reference point.
Pregnancy and lower limits
For people who are pregnant, trying to become pregnant, or breastfeeding, the American College of Obstetricians and Gynecologists cites 200 mg per day as a moderate caffeine limit.
At 63 mg per espresso shot, 3 shots provide about 189 mg. A 4th shot would bring the day to about 252 mg, which exceeds the 200 mg pregnancy guidance.
Worked daily examples
Example 1: two espresso shots in a latte provide about 126 mg. That leaves about 274 mg before reaching 400 mg for a healthy adult.
Example 2: a morning 2-shot drink plus an afternoon 2-shot drink totals about 252 mg. That is below 400 mg, but above the 200 mg pregnancy guideline.
Example 3: a 3-shot espresso drink is about 189 mg. Add one more single shot later and the day reaches about 252 mg.
Example 4: four single shots spread across the day equal about 252 mg. Six single shots equal about 378 mg.
Count all caffeine sources
The daily total includes espresso, drip coffee, cold brew, tea, soda, energy drinks, chocolate, and some medicines or supplements.
Caffeine varies by coffee bean, roast, grind, dose, and shot size. A “single” at one café may not match a 1 fl oz reference shot.
If caffeine causes anxiety, insomnia, rapid heartbeat, reflux, or headaches, a lower personal limit may be more useful than the 400 mg adult benchmark.

Reader Questions
How much caffeine is in one shot of espresso?
One single shot of espresso, typically 1 fl oz, has about 60-75 mg of caffeine. The exact amount depends on the coffee beans, grind, dose, and extraction time, but 60-75 mg is the typical range for a standard single shot.
Does espresso have more caffeine than brewed coffee?
Per ounce, espresso is stronger: one 1 fl oz shot has 60-75 mg caffeine. But a typical 8 fl oz brewed coffee has 80-100 mg total, so a full cup of brewed coffee usually has more caffeine than one espresso shot.
How much caffeine is in 2 shots of espresso?
Two single shots of espresso contain about 120-150 mg of caffeine total. That estimate doubles the typical 60-75 mg found in one 1 fl oz espresso shot. Actual caffeine can vary with the coffee and how the shots are pulled.
Is one shot of espresso the same caffeine as a cup of coffee?
No. One 1 fl oz espresso shot has about 60-75 mg caffeine, while an 8 fl oz brewed coffee has about 80-100 mg. Espresso is more concentrated, but the larger serving of brewed coffee usually provides more total caffeine.
How does espresso caffeine compare with tea and energy drinks?
One 1 fl oz espresso shot has 60-75 mg caffeine. An 8 fl oz black tea has 40-70 mg, green tea has 20-45 mg, and an 8 fl oz energy drink has 70-100 mg. So espresso is close to black tea and some energy drinks.
