A 1 fl oz single shot of espresso typically has 60-75 mg of caffeine. A double shot, if made with two single shots, would usually be about 120-150 mg, depending on the beans, grind, and extraction.
How Much Caffeine In A Shot Of Espresso: a 1 fl oz single shot typically has 60-75 mg of caffeine. That is less liquid than an 8 fl oz brewed coffee, but it is more concentrated per ounce.
For comparison, 8 fl oz brewed coffee has 80-100 mg, instant coffee has 30-90 mg, and decaf coffee has 2-15 mg. So one espresso shot is usually close to a small cup of coffee in caffeine, not “caffeine-free” or unusually extreme.
The Short Answer, With Numbers
A single 1 fl oz shot of espresso typically has 60-75 mg of caffeine. If you order two shots, use simple multiplication: a double espresso is about 120-150 mg.
The key point is serving size. Espresso is concentrated, but the standard shot is small. An 8 fl oz brewed coffee is larger and typically has 80-100 mg, so one shot of espresso usually has less total caffeine.
| Drink | Typical serving | Caffeine | What that means for espresso comparison |
|---|---|---|---|
| Espresso | 1 fl oz single shot | 60-75 mg | Baseline: one standard shot |
| Brewed coffee | 8 fl oz | 80-100 mg | More caffeine than one espresso shot |
| Instant coffee | 8 fl oz | 30-90 mg | Can be lower or higher than one shot |
| Decaf coffee | 8 fl oz | 2-15 mg | Far below one espresso shot |
| Cold brew | 8 fl oz | 100-200 mg | Usually higher than one shot |
Fast Math For Common Espresso Orders
For espresso drinks, count the shots first. One shot gives 60-75 mg. Two shots give 120-150 mg. Three shots give 180-225 mg.
A latte, cappuccino, flat white, macchiato, or Americano may taste very different, but the caffeine depends mostly on shot count. Milk and hot water change volume and flavor, not the espresso caffeine number.
Example: a 12 fl oz latte made with one shot has about 60-75 mg. A 16 fl oz latte made with two shots has about 120-150 mg. The larger cup is not the issue; the extra shot is.
Example: an Americano made with one shot and added water still has about 60-75 mg. If it is made with two shots, it rises to about 120-150 mg.
How One Shot Compares To Coffee
One espresso shot has 60-75 mg. An 8 fl oz brewed coffee has 80-100 mg. So a regular cup of brewed coffee typically beats a single shot by about 5-40 mg.
A double espresso, however, has 120-150 mg. That is more than an 8 fl oz brewed coffee at 80-100 mg. The double shot is the point where espresso usually overtakes a standard cup.
Instant coffee overlaps with espresso. An 8 fl oz instant coffee ranges from 30-90 mg, so it can be below a shot, equal to a shot, or slightly above a shot depending on the product and mix strength.
Cold brew is a different case. At 100-200 mg per 8 fl oz, it is usually higher than one espresso shot and can exceed a double espresso at the top of the range.
Decaf coffee is not caffeine-free, but it is much lower. An 8 fl oz decaf coffee has 2-15 mg, compared with 60-75 mg in a single espresso shot.
Caffeine In One Espresso Shot
One 1 fl oz single shot of espresso typically has 60-75 mg of caffeine. That is the practical number to use when counting caffeine from a standard espresso shot.
If a drink menu says “single espresso,” assume 1 fl oz and about 60-75 mg caffeine. The midpoint is about 68 mg, useful for quick math when the exact café recipe is unknown.
Quick Caffeine Math For Espresso Drinks
| Order | Espresso volume | Typical caffeine |
|---|---|---|
| Single espresso | 1 fl oz | 60-75 mg |
| Double espresso | 2 fl oz | 120-150 mg |
| Triple espresso | 3 fl oz | 180-225 mg |
A double shot is not a different caffeine category; it is usually two single shots. So double the single-shot range: 2 × 60-75 mg = 120-150 mg.
A triple shot is three single shots. Use 3 × 60-75 mg = 180-225 mg. This is common in large lattes, iced espresso drinks, and extra-shot orders.
Espresso Compared With Coffee And Tea
| Drink | Typical serving | Caffeine range |
|---|---|---|
| Espresso | 1 fl oz | 60-75 mg |
| Brewed coffee | 8 fl oz | 80-100 mg |
| Cold brew | 8 fl oz | 100-200 mg |
| Black tea | 8 fl oz | 40-70 mg |
| Green tea | 8 fl oz | 20-45 mg |
Per ounce, espresso is more concentrated than brewed coffee. But per usual serving, one espresso shot often has less caffeine than an 8 fl oz brewed coffee.
Example: one espresso shot gives 60-75 mg. One 8 fl oz brewed coffee gives 80-100 mg. The coffee has about 5-40 mg more caffeine than the single shot.
Cold brew can be much higher by serving. An 8 fl oz cold brew has 100-200 mg, compared with 60-75 mg in one espresso shot.
Worked Examples
Example 1: A cappuccino made with one shot has about 60-75 mg caffeine. The milk changes the drink size, not the caffeine from the espresso.
Example 2: A latte made with two shots has about 120-150 mg caffeine. That equals the caffeine from two 1 fl oz espresso shots.
Example 3: An iced drink with three shots has about 180-225 mg caffeine. Ice, milk, and syrup do not reduce the caffeine already in the espresso.
Example 4: An Americano made with one shot has 60-75 mg caffeine. Adding hot water increases volume but does not add caffeine.
Edge Cases That Change The Number
A “shot” can mean different things at different cafés. If the drink uses more than 1 fl oz of espresso or multiple shots, count each 1 fl oz single shot as 60-75 mg.
A ristretto may be smaller in volume, and a lungo may be larger. If the menu still builds the drink from one espresso dose, the exact caffeine can vary, but use 60-75 mg as the standard single-shot estimate.
Decaf espresso is not caffeine-free, but the provided decaf figure is for 8 fl oz decaf coffee: 2-15 mg. Do not apply that directly to a 1 fl oz espresso shot unless the café provides its own number.
For fast counting, use 75 mg per shot when estimating high, 60 mg per shot when estimating low, or 68 mg per shot for a middle estimate.
Single Versus Double Shot
A single shot of espresso is typically 1 fl oz and contains 60-75 mg of caffeine. A double shot is two single shots, so it is typically 2 fl oz and contains 120-150 mg of caffeine.
| Espresso order | Volume | Caffeine |
|---|---|---|
| Single shot | 1 fl oz | 60-75 mg |
| Double shot | 2 fl oz | 120-150 mg |
| Two separate singles | 2 fl oz total | 120-150 mg total |
Quick Rule For Counting Shots
Count 60-75 mg for each 1 fl oz shot. If your drink has 1 shot, use 60-75 mg. If it has 2 shots, use 120-150 mg. If it has 3 shots, use 180-225 mg.
Worked example: a cappuccino made with 1 shot has 60-75 mg. The milk changes the size of the drink, but not the espresso caffeine count.
Worked example: a latte made with 2 shots has 120-150 mg. Even if the cup is much larger than the espresso volume, the caffeine comes from the 2 fl oz of espresso.
Worked example: an Americano made with 2 shots and hot water has 120-150 mg. Adding water changes strength and volume, not the amount of caffeine already extracted.
Single Or Double Compared With Coffee
An 8 fl oz brewed coffee has 80-100 mg of caffeine. That means a single espresso, at 60-75 mg, usually has less caffeine than a standard 8 fl oz brewed coffee.
A double espresso, at 120-150 mg, usually has more caffeine than an 8 fl oz brewed coffee. It is smaller in volume but higher in total caffeine than that coffee serving.
| Drink | Serving | Caffeine |
|---|---|---|
| Espresso, single | 1 fl oz | 60-75 mg |
| Espresso, double | 2 fl oz | 120-150 mg |
| Brewed coffee | 8 fl oz | 80-100 mg |
| Cold brew | 8 fl oz | 100-200 mg |
Edge Cases That Change The Answer
If a cafe calls a drink “small” but uses 2 shots, count it as 120-150 mg. Cup size is not the key number; shot count is.
If a cafe uses a double shot as its default espresso pull, then “one espresso” may mean 2 fl oz and 120-150 mg, not a 1 fl oz single.
If you order an extra shot, add 60-75 mg. A 2-shot drink with one extra shot becomes 3 shots, or 180-225 mg total.
If you split a double shot into two small drinks, each half contains about one shot’s worth of caffeine: 60-75 mg per half, assuming the split is even.
Decaf is different. An 8 fl oz decaf coffee has 2-15 mg, but that figure is for decaf coffee, not a decaf espresso shot. Use the cafe’s stated number if available.
Bottom line for ordering: single espresso equals 60-75 mg; double espresso equals 120-150 mg. For mixed espresso drinks, multiply 60-75 mg by the number of shots.
What Changes Caffeine Amount
A 1 fl oz single shot of espresso typically has 60-75 mg caffeine. The number changes most when the drink changes from a true single shot to a larger, smaller, or multi-shot espresso drink.
Shot Count Changes The Total Fastest
The easiest calculation is by shot count. Use 60-75 mg per 1 fl oz shot, then multiply by the number of shots in the cup.
| Espresso order | Espresso 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 |
Worked example: if your latte has 2 shots, it has about 120-150 mg caffeine from espresso before any chocolate, tea, or coffee syrup ingredients are added.
Another example: a 3-shot iced espresso drink lands around 180-225 mg. That is more caffeine than a typical 8 fl oz brewed coffee at 80-100 mg.
Drink Size Does Not Equal Caffeine Size
A 12 fl oz cappuccino and a 16 fl oz latte can have the same caffeine if each is made with the same number of espresso shots. Milk and ice add volume, not espresso caffeine.
For example, a 16 fl oz latte with 1 shot is still about 60-75 mg. A smaller 8 fl oz drink with 2 shots is about 120-150 mg.
Espresso Versus Other Caffeinated Drinks
Espresso looks strong because it is concentrated. Per serving, though, a single shot is often close to a cup of coffee or tea rather than automatically higher.
| Drink | Serving | Typical caffeine |
|---|---|---|
| Espresso | 1 fl oz | 60-75 mg |
| Brewed coffee | 8 fl oz | 80-100 mg |
| Instant coffee | 8 fl oz | 30-90 mg |
| Cold brew | 8 fl oz | 100-200 mg |
| Black tea | 8 fl oz | 40-70 mg |
Edge case: one single espresso at 60-75 mg can be lower than an 8 fl oz brewed coffee at 80-100 mg, but two shots at 120-150 mg are usually higher.
Cold brew is another edge case. An 8 fl oz cold brew at 100-200 mg can overlap with, or exceed, a double espresso at 120-150 mg.
Added Ingredients Can Add Caffeine
Mocha-style drinks may add caffeine from chocolate. Dark chocolate has 10-25 mg per 1 oz. That caffeine is in addition to the espresso shots.
Worked example: a single-shot mocha with 1 oz dark chocolate is about 70-100 mg total: 60-75 mg from espresso plus 10-25 mg from dark chocolate.
A double-shot mocha with 1 oz dark chocolate is about 130-175 mg: 120-150 mg from espresso plus 10-25 mg from chocolate.
Decaf Espresso Is Not The Same As Zero
The reference figure for decaf coffee is 2-15 mg per 8 fl oz. If a drink is labeled decaf, do not treat it as caffeine-free unless the shop gives its own tested number.
For regular espresso, the practical answer remains simple: count the shots. One shot is 60-75 mg, two shots are 120-150 mg, and three shots are 180-225 mg.
How To Estimate Your Shot
Use 60-75 mg caffeine for a typical 1 fl oz single shot of espresso. That is the best working range when you do not have the cafe’s lab-tested number.
Fast estimate formula
Estimate espresso caffeine by scaling the shot volume: caffeine ≈ shot ounces × 60-75 mg. This assumes the drink is espresso-strength and the “shot” is close to a standard single.
- 1. Measure the liquid espresso, not the cup size. A single shot is listed as 1 fl oz. If your demitasse has 2 fl oz of space but only 1 fl oz of espresso, estimate 60-75 mg.
- 2. Use the standard single-shot range first. For any normal 1 fl oz espresso shot, write down 60-75 mg. The midpoint is 67.5 mg, useful when you need one number for tracking.
- 3. Scale by ounce when the pour is larger or smaller. A 0.5 fl oz short shot estimates at 30-37.5 mg. A 1.5 fl oz shot estimates at 90-112.5 mg. A 2 fl oz double estimates at 120-150 mg.
- 4. Count shots in milk drinks. A latte, cappuccino, or Americano has the espresso caffeine from its shots. One 1 fl oz shot is 60-75 mg. Two 1 fl oz shots are 120-150 mg.
- 5. Do not count added water or milk as more caffeine. If a drink has 1 fl oz espresso plus 7 fl oz milk, estimate 60-75 mg, not an 8 fl oz coffee amount.
- 6. Treat cafe “double shots” carefully. If the cafe means two 1 fl oz shots, use 120-150 mg. If it means one larger 1.5 fl oz pull, use 90-112.5 mg.
- 7. Compare with other drinks only by serving size. One espresso shot, 60-75 mg, can overlap black tea at 40-70 mg, but it is below typical 8 fl oz cold brew at 100-200 mg.
Worked examples
Example 1: You drink one straight 1 fl oz espresso. Estimate 60-75 mg. If your log needs one value, enter about 68 mg.
Example 2: Your iced latte has two standard shots. Estimate 2 × 60-75 mg = 120-150 mg. Ice and milk do not change the caffeine estimate.
Example 3: Your cafe pours a 1.5 fl oz “long” espresso. Estimate 1.5 × 60-75 mg = 90-112.5 mg.
Example 4: You split a double espresso with someone. If the double is two 1 fl oz shots, the whole drink is 120-150 mg. Half is 60-75 mg.
| Espresso amount | Estimated caffeine |
|---|---|
| 0.5 fl oz | 30-37.5 mg |
| 1 fl oz | 60-75 mg |
| 1.5 fl oz | 90-112.5 mg |
| 2 fl oz | 120-150 mg |
Edge case: a cafe menu may say “espresso” but serve a small brewed-coffee-style drink. If it is not a 1 fl oz espresso shot, do not use the espresso estimate blindly.
Edge case: decaf espresso is not covered by the espresso figure above. The available decaf figure is for 8 fl oz decaf coffee: 2-15 mg. Use the cafe’s number if you need decaf espresso specifically.
Espresso Compared With Coffee
A single 1 fl oz shot of espresso typically has 60-75 mg of caffeine. An 8 fl oz cup of brewed coffee typically has 80-100 mg.
That means espresso is stronger by volume, but brewed coffee usually gives you more caffeine per normal serving.
| Drink | Typical serving | Caffeine |
|---|---|---|
| Espresso | 1 fl oz single shot | 60-75 mg |
| Brewed coffee | 8 fl oz | 80-100 mg |
| Instant coffee | 8 fl oz | 30-90 mg |
| Decaf coffee | 8 fl oz | 2-15 mg |
| Cold brew | 8 fl oz | 100-200 mg |
Caffeine Per Ounce
Espresso: 60-75 mg in 1 fl oz equals 60-75 mg per fl oz.
Brewed coffee: 80-100 mg in 8 fl oz equals 10-12.5 mg per fl oz.
So espresso has about 6 times as much caffeine per ounce as brewed coffee at the low end: 60 mg versus 10 mg.
At the high end, espresso has about 6 times as much per ounce again: 75 mg versus 12.5 mg.
This is why a tiny espresso tastes and feels concentrated, even though the full cup of brewed coffee often contains more total caffeine.
Worked Examples
One espresso shot: 1 fl oz gives 60-75 mg caffeine.
One brewed coffee: 8 fl oz gives 80-100 mg caffeine.
Compared serving to serving, brewed coffee has 5-40 mg more caffeine than one espresso shot.
At the low comparison, brewed coffee is 80 mg and espresso is 75 mg, so coffee has 5 mg more.
At the wide comparison, brewed coffee is 100 mg and espresso is 60 mg, so coffee has 40 mg more.
Two espresso shots: 2 fl oz gives 120-150 mg caffeine, using 60-75 mg per shot.
Two shots beat a typical 8 fl oz brewed coffee, which has 80-100 mg.
The difference is 20-70 mg more caffeine for two espresso shots than for one brewed coffee.
Edge Cases: Instant, Decaf, And Cold Brew
Instant coffee ranges from 30-90 mg per 8 fl oz. One espresso shot at 60-75 mg can be stronger or weaker than instant, depending on the cup.
A low instant coffee at 30 mg has half the caffeine of a 60 mg espresso shot.
A high instant coffee at 90 mg has 15 mg more caffeine than a 75 mg espresso shot.
Decaf coffee is much lower: 2-15 mg per 8 fl oz. One espresso shot has 45-73 mg more caffeine than an 8 fl oz decaf coffee.
Cold brew is the major exception. An 8 fl oz cold brew has 100-200 mg, which is more than one espresso shot and often more than two shots.
One espresso shot is 60-75 mg. Two shots are 120-150 mg. An 8 fl oz cold brew can still reach 200 mg.
For a fast comparison: one espresso shot is less than brewed coffee by serving, stronger by ounce, and far above decaf.
Frequently Asked Questions
How much caffeine is in one shot of espresso?
A single 1 fl oz shot of espresso typically has 60-75 mg of caffeine. The exact amount varies by coffee bean, grind, dose, and extraction, but 60-75 mg is the typical range for a standard single shot.
Does espresso have more caffeine than regular coffee?
Per ounce, espresso is stronger, but per serving brewed coffee often has more caffeine. One 1 fl oz espresso shot has 60-75 mg, while an 8 fl oz brewed coffee has 80-100 mg. Serving size makes the biggest difference.
How much caffeine is in 2 shots of espresso?
Two single shots of espresso typically contain about 120-150 mg of caffeine total. That estimate comes from 60-75 mg per 1 fl oz shot, doubled. Actual caffeine can vary depending on the coffee and how the shots are pulled.
Is a shot of espresso stronger than an energy drink?
A single espresso shot has 60-75 mg of caffeine. An 8 fl oz energy drink typically has 70-100 mg. So one energy drink usually has slightly more caffeine than one espresso shot, though espresso is more concentrated by volume.
How does espresso compare with black tea or green tea?
One 1 fl oz espresso shot has 60-75 mg of caffeine. An 8 fl oz black tea has 40-70 mg, and an 8 fl oz green tea has 20-45 mg. Espresso usually has more caffeine than green tea and often overlaps with black tea.
