A 1 fl oz single shot of espresso typically has 60-75 mg of caffeine. Exact caffeine varies by bean, roast, grind, dose, and extraction, but 60-75 mg is the practical range to use for one standard espresso shot.
How Many Mg Of Caffeine In A Shot Of Espresso: a 1 fl oz single shot typically has 60-75 mg of caffeine. That’s less total caffeine than most 8 fl oz brewed coffees, which typically have 80-100 mg.
Espresso tastes stronger because it is concentrated, not because one shot always has more caffeine. If you drink a double shot, estimate roughly two single shots, or about 120-150 mg, based on the typical 60-75 mg per 1 fl oz shot.
The Short Answer, With Numbers
A 1 fl oz single shot of espresso typically has 60-75 mg of caffeine. If you order one standard shot, that is the number to use for quick caffeine math.
| 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 |
What That Means Per Shot
For a single espresso, count 60-75 mg caffeine per 1 fl oz shot. A double made from two standard shots is about 120-150 mg.
A triple espresso is about 180-225 mg. That is just the single-shot range multiplied by 3: 60 mg × 3 on the low end, and 75 mg × 3 on the high end.
If a drink has “2 shots,” do not count it as one coffee. Count the shots. A 2-shot latte, cappuccino, americano, or flat white is typically 120-150 mg from espresso.
Espresso Versus Coffee By Serving
One espresso shot has less caffeine than a typical 8 fl oz brewed coffee. Espresso is 60-75 mg; brewed coffee is 80-100 mg per 8 fl oz.
But espresso is more concentrated. Per fluid ounce, espresso is 60-75 mg per fl oz. Brewed coffee is roughly 10-12.5 mg per fl oz when an 8 fl oz cup has 80-100 mg.
That means 1 fl oz of espresso can carry about as much caffeine as roughly 5 to 7 fl oz of brewed coffee, depending on where each drink falls in its typical range.
Worked Examples
One shot: 1 × 60-75 mg = 60-75 mg.
Two shots: 2 × 60-75 mg = 120-150 mg.
Three shots: 3 × 60-75 mg = 180-225 mg.
Four shots: 4 × 60-75 mg = 240-300 mg.
If you switch from one 8 fl oz brewed coffee to one espresso shot, your caffeine usually drops from 80-100 mg to 60-75 mg.
If you switch from one 8 fl oz cold brew to one espresso shot, your caffeine usually drops more sharply: cold brew is 100-200 mg, while one espresso is 60-75 mg.
Edge Cases To Count Correctly
A “shot” means 1 fl oz here. If your café uses a different shot size or recipe, the caffeine can shift, but the standard reference number is still 60-75 mg per 1 fl oz shot.
Do not compare espresso and brewed coffee only by cup size. Compare by serving first: 1 shot espresso is 60-75 mg; 8 fl oz brewed coffee is 80-100 mg.
For mixed espresso drinks, milk and ice do not add caffeine. The caffeine estimate comes from the number of espresso shots: 1 shot is 60-75 mg, 2 shots are 120-150 mg.
Caffeine in one espresso shot
One single shot of espresso, 1 fl oz, typically has 60 to 75 mg of caffeine. Use 60 mg as the low estimate, 75 mg as the high estimate, and about 68 mg as a practical midpoint.
If a menu says “single espresso,” the best estimate is 60–75 mg caffeine for a 1 fl oz shot. The caffeine number is not doubled by the small cup size; espresso is concentrated, not caffeine-free or unusually tiny in effect.
Quick espresso caffeine amounts
| Espresso order | Assumed volume | Estimated caffeine |
|---|---|---|
| Single shot | 1 fl oz | 60–75 mg |
| Two single shots | 2 fl oz total | 120–150 mg |
| Three single shots | 3 fl oz total | 180–225 mg |
| Four single shots | 4 fl oz total | 240–300 mg |
Worked example: if your latte contains 2 espresso shots, multiply 60–75 mg by 2. That drink contains about 120–150 mg caffeine from espresso before counting any other caffeinated ingredient.
Another example: an Americano made with 3 espresso shots contains about 180–225 mg caffeine. Adding hot water changes the volume and strength per sip, but it does not remove caffeine from the espresso.
A 4-shot espresso drink is a high-caffeine café order. Using the typical range, 4 shots provide about 240–300 mg caffeine from espresso alone.
Espresso compared with coffee and tea
| 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 |
| Cold brew | 8 fl oz | 100–200 mg |
| Black tea | 8 fl oz | 40–70 mg |
| Green tea | 8 fl oz | 20–45 mg |
A single espresso shot usually has less caffeine than an 8 fl oz brewed coffee. Espresso is stronger per ounce, but the serving is much smaller: 1 fl oz versus 8 fl oz.
Compared with black tea, one espresso shot is often similar or slightly higher. Black tea is 40–70 mg per 8 fl oz, while espresso is 60–75 mg per 1 fl oz.
Compared with green tea, espresso is clearly higher. One 1 fl oz espresso shot has 60–75 mg, while 8 fl oz green tea has 20–45 mg.
Edge cases that change the answer
If a drink is labeled “double,” do not assume the caffeine is still 60–75 mg. A double made from 2 single shots is about 120–150 mg caffeine.
If the cup is larger because milk, ice, or water was added, the espresso caffeine stays tied to the shot count. A 12 fl oz latte with 1 shot still has about 60–75 mg from espresso.
If you are estimating a mixed drink, count shots first. One shot is 60–75 mg, two shots are 120–150 mg, three shots are 180–225 mg, and four shots are 240–300 mg.
Do not compare espresso to cold brew by cup size alone. An 8 fl oz cold brew typically has 100–200 mg, which can exceed one or two espresso shots depending on the exact drink.
For a fast rule: 1 espresso shot equals 60–75 mg caffeine; every added shot adds another 60–75 mg.
Single vs double shot amounts
A single 1 fl oz shot of espresso typically has 60-75 mg of caffeine. A double shot, if it is two 1 fl oz shots, is typically 120-150 mg.
Quick espresso caffeine table
| Espresso order | Fluid ounces | Typical 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 |
| Three single shots | 3 fl oz total | 180-225 mg total |
The math is direct: one espresso shot is 60-75 mg. A double is two singles, so multiply by 2. That gives 120 mg on the low end and 150 mg on the high end.
Worked example: if your latte is made with one shot, count 60-75 mg. If the same latte is made with a double shot, count 120-150 mg, before adding any other caffeinated ingredient.
Another example: two cappuccinos with one shot each equal 120-150 mg total. That is the same caffeine range as one double-shot drink, because both contain two 1 fl oz espresso shots.
How a double compares with coffee
An 8 fl oz brewed coffee is typically 80-100 mg. A double espresso at 120-150 mg is higher than that typical brewed-coffee range, even though it is only 2 fl oz.
A single espresso at 60-75 mg is below an 8 fl oz brewed coffee range of 80-100 mg. It is stronger by volume, but the total caffeine in the small serving is usually lower.
Cold brew is listed at 100-200 mg per 8 fl oz. A double espresso at 120-150 mg sits inside that cold-brew range, while a single espresso at 60-75 mg is below it.
Ordering edge cases
If a menu says “double,” count it as 120-150 mg only when it means two 1 fl oz espresso shots. If the shop uses different shot sizing, the caffeine may not match this simple two-shot calculation.
If you ask for “an extra shot,” add 60-75 mg for each added 1 fl oz shot. A drink that starts as a double and gets one extra shot becomes 180-225 mg total.
If you split a double-shot drink into two equal portions, each half contains about one single shot’s worth of caffeine: 60-75 mg per half, assuming the espresso is evenly mixed.
Decaf espresso is not covered in the provided figures. For decaf coffee, the listed 8 fl oz range is 2-15 mg, but that number should not be used to calculate a decaf espresso shot.
For a fast estimate, use 75 mg as the high end per single shot and 150 mg as the high end per double shot. Use 60 mg and 120 mg for the low-end estimate.
What changes the caffeine amount
A standard single shot of espresso is 1 fl oz and typically has 60-75 mg of caffeine. The biggest changes come from how many shots are used, how the shop defines a “shot,” and whether espresso is compared by ounce or by serving.
Number of shots is the fastest multiplier
If one espresso shot is 60-75 mg, two shots are 120-150 mg. Three shots are 180-225 mg. Four shots are 240-300 mg. This is why a small latte and a large latte can differ sharply if the larger size adds shots.
| 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 |
| Quad shot | 4 fl oz | 240-300 mg |
Worked example: if your cappuccino has 1 shot, expect 60-75 mg. If your iced latte has 3 shots, expect 180-225 mg. The milk, ice, foam, or syrup does not add espresso caffeine unless more shots are added.
Serving size can hide the dose
Espresso is concentrated because the serving is small. A 1 fl oz shot has 60-75 mg. An 8 fl oz brewed coffee has 80-100 mg, so the coffee cup has more total caffeine than one shot, but much less caffeine per fluid ounce.
Per-ounce comparison: espresso is 60-75 mg per fl oz. Brewed coffee is 80-100 mg per 8 fl oz, or about 10-12.5 mg per fl oz. Espresso is therefore far stronger by volume.
Cold brew shows the opposite edge case. An 8 fl oz cold brew has 100-200 mg. That means one cold brew serving can equal about 1.3 to 3.3 single espresso shots, depending on where each drink falls in its typical range.
Menu wording matters
“Single,” “double,” and “extra shot” are the key words. A double is not just a larger-looking drink; it is usually 2 espresso shots. Using the typical range, that moves the drink from 60-75 mg to 120-150 mg.
Edge case: a small drink with 2 shots can have more caffeine than a large drink with 1 shot. Size in ounces is not enough. Count the espresso shots first, then multiply by 60-75 mg per shot.
Another edge case is a decaf espresso-style drink. The reference figure for decaf coffee is 2-15 mg per 8 fl oz, not a specific espresso-shot figure. Without the shop’s data, do not assume decaf espresso is zero caffeine.
Comparison with other caffeine sources
A single espresso shot at 60-75 mg is close to an 8 fl oz black tea at 40-70 mg. It is usually more than a 12 fl oz cola at 30-40 mg, and less than many 8 fl oz cold brews at 100-200 mg.
An 8 fl oz energy drink at 70-100 mg overlaps with espresso. One shot can be slightly lower, similar, or close to the lower end of that energy drink range. Two shots, at 120-150 mg, usually exceed it.
Dark chocolate adds smaller amounts. One ounce has 10-25 mg. A single espresso shot equals about 2.4 to 7.5 ounces of dark chocolate by caffeine, depending on the espresso and chocolate values used.
How to measure your intake
Count espresso by the shot, then convert each shot to milligrams. A 1 fl oz single shot of espresso has about 60-75 mg caffeine.
- 1. Write down the serving size first. Use 1 fl oz as the espresso unit. If you drink one single shot, count 60-75 mg. If your drink has two single shots, count 120-150 mg.
- 2. Count hidden espresso shots in café drinks. A latte, cappuccino, flat white, mocha, or iced espresso drink may contain more than one shot. If the cup has 2 shots, use 2 × 60-75 mg = 120-150 mg.
- 3. Use a range, not one exact number. Espresso varies, so log it as 60-75 mg per 1 fl oz shot. Three single shots equal 180-225 mg, not one fixed number.
- 4. Add other caffeinated drinks separately. Do not treat all coffee as espresso. An 8 fl oz brewed coffee is 80-100 mg, while an 8 fl oz cold brew is 100-200 mg.
- 5. Include tea, soda, energy drinks, and chocolate. Black tea is 40-70 mg per 8 fl oz. Green tea is 20-45 mg per 8 fl oz. Cola is 30-40 mg per 12 fl oz. Dark chocolate is 10-25 mg per 1 oz.
- 6. Total the low end and high end. Add the smallest numbers for your minimum estimate, then add the largest numbers for your maximum estimate. This gives a practical daily range.
Worked examples
Example 1: one espresso shot plus one 8 fl oz brewed coffee. Espresso is 60-75 mg. Brewed coffee is 80-100 mg. Total: 140-175 mg.
Example 2: a 2-shot latte plus 1 oz dark chocolate. Espresso is 120-150 mg. Dark chocolate is 10-25 mg. Total: 130-175 mg.
Example 3: three espresso shots and one 8 fl oz green tea. Espresso is 180-225 mg. Green tea is 20-45 mg. Total: 200-270 mg.
Example 4: one espresso shot, one 12 fl oz cola, and one 8 fl oz black tea. Add 60-75 mg, 30-40 mg, and 40-70 mg. Total: 130-185 mg.
Edge cases that change the math
A “double espresso” should be counted as two 1 fl oz shots if that is how it was made. That makes it 120-150 mg, not 60-75 mg.
Decaf is not zero. An 8 fl oz decaf coffee has 2-15 mg. If you drink decaf with espresso drinks, count both instead of ignoring the decaf.
Instant coffee is separate from espresso. An 8 fl oz instant coffee has 30-90 mg, so one espresso plus one instant coffee totals 90-165 mg.
Cold brew can exceed espresso per serving. One 8 fl oz cold brew is 100-200 mg, while one espresso shot is 60-75 mg.
For the cleanest daily log, make four columns: item, serving, low caffeine, high caffeine. Use 60 and 75 for each 1 fl oz espresso shot, then total the columns.
Espresso vs regular 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 per ounce, but brewed coffee usually has more caffeine per serving because the serving is much larger.
| Drink | Typical serving | Caffeine | Mg per fl oz |
|---|---|---|---|
| Espresso | 1 fl oz | 60-75 mg | 60-75 mg |
| Brewed coffee | 8 fl oz | 80-100 mg | 10-12.5 mg |
Per ounce, espresso has about 6 times as much caffeine as brewed coffee at the low end: 60 mg versus 10 mg per fl oz.
At the high end, espresso also has about 6 times as much per ounce: 75 mg versus 12.5 mg per fl oz.
Which has more caffeine: 1 shot or 1 cup?
An 8 fl oz brewed coffee has 80-100 mg. One espresso shot has 60-75 mg. So one regular cup usually has 5-40 mg more caffeine than one shot.
Example: compare a 75 mg espresso shot with an 80 mg brewed coffee. The brewed coffee is only 5 mg higher, so they are close.
Another example: compare a 60 mg espresso shot with a 100 mg brewed coffee. The brewed coffee has 40 mg more.
What about a double shot?
A double espresso is commonly two 1 fl oz shots. Using the listed range, that is 120-150 mg of caffeine in 2 fl oz.
That double shot has more caffeine than an 8 fl oz brewed coffee at 80-100 mg. The difference is 20-70 mg more for the double espresso.
Worked example: two 60 mg shots equal 120 mg. Compared with a 100 mg brewed coffee, the double espresso has 20 mg more.
At the other edge, two 75 mg shots equal 150 mg. Compared with an 80 mg brewed coffee, the double espresso has 70 mg more.
Espresso drinks can add up fast
A latte, cappuccino, or Americano may contain one or more espresso shots. The caffeine depends mainly on the shot count, not the milk or added hot water.
| Espresso amount | Caffeine range | Compared with 8 fl oz brewed coffee |
|---|---|---|
| 1 shot | 60-75 mg | Usually lower |
| 2 shots | 120-150 mg | Higher |
| 3 shots | 180-225 mg | Much higher |
A 3-shot espresso drink gives 180-225 mg. That is 80-145 mg more than an 8 fl oz brewed coffee at 80-100 mg.
Edge case: a small espresso drink with one strong shot, 75 mg, can be close to a mild 8 fl oz brewed coffee, 80 mg. The gap is only 5 mg.
Opposite edge: a 3-shot drink at 225 mg has more than double the caffeine of a 100 mg brewed coffee serving.
Bottom line: espresso is more concentrated, but serving size decides the total. One shot is usually less than one 8 fl oz coffee; two shots are higher.
Frequently Asked Questions
How many mg of caffeine are in one shot of espresso?
One 1 fl oz single shot of espresso typically has 60-75 mg of caffeine. The exact amount varies by coffee bean, roast, grind, dose, and extraction, but 60-75 mg is the practical range to use for estimating caffeine.
Does espresso have more caffeine than brewed coffee?
Per ounce, espresso is more concentrated, but per typical serving, brewed coffee often has more. A 1 fl oz espresso has 60-75 mg caffeine, while an 8 fl oz brewed coffee has 80-100 mg caffeine.
How much caffeine is in a double shot of espresso?
Using the typical 60-75 mg per 1 fl oz single shot, a double shot would usually provide about 120-150 mg of caffeine. The total can vary with the coffee used and how the espresso is pulled.
How does espresso compare with cold brew for caffeine?
A 1 fl oz espresso shot has about 60-75 mg caffeine. An 8 fl oz cold brew typically has 100-200 mg. So a standard serving of cold brew usually has more total caffeine than one espresso shot.
How much caffeine is in decaf espresso?
