A double shot of espresso typically has 120-150 mg of caffeine, based on 60-75 mg in a 1 fl oz single shot. Actual caffeine varies by bean, grind, dose, and extraction, but that range is the standard estimate.
How Much Caffeine In A Double Shot Of Espresso: a double shot has about 120-150 mg of caffeine, based on 60-75 mg in a typical 1 fl oz single espresso shot.
That means a double espresso usually delivers more caffeine than an 8 fl oz brewed coffee at 80-100 mg, but less than many 8 fl oz cold brews at 100-200 mg. Exact caffeine can vary by bean, grind, dose, and extraction.
The Short Answer, With Numbers
A double shot of espresso has about 120-150 mg of caffeine. That is based on 2 single 1 fl oz espresso shots, each with 60-75 mg of caffeine.
| Drink | Serving size | Caffeine | What it means for a double espresso question |
|---|---|---|---|
| Espresso | 1 fl oz single shot | 60-75 mg | One shot; double it for a 2-shot drink |
| Espresso | 2 fl oz double shot | 120-150 mg | The usual answer for a true double shot |
| Brewed coffee | 8 fl oz | 80-100 mg | A double espresso is usually higher than one cup |
| Cold brew | 8 fl oz | 100-200 mg | A double espresso can overlap the lower-to-middle part of this range |
| Energy drink | 8 fl oz | 70-100 mg | A double espresso is usually more caffeine |
Quick calculation
Use this math: 60-75 mg per shot x 2 shots = 120-150 mg. If your drink is made with two espresso shots, that is the caffeine range to use.
A 2 fl oz double espresso is small in volume, but not small in caffeine. It has more caffeine than an 8 fl oz brewed coffee listed at 80-100 mg.
Compared with brewed coffee, the low end of a double espresso is 20 mg higher than a 100 mg cup. The high end is 70 mg higher than an 80 mg cup.
Compared with an 8 fl oz energy drink at 70-100 mg, a double espresso at 120-150 mg is higher across the full range.
Compared with 8 fl oz cold brew at 100-200 mg, a double espresso falls inside the cold brew range. It is more than a 100 mg cold brew, but less than a 200 mg cold brew.
Worked examples
If a latte is made with a double shot, count the espresso as 120-150 mg of caffeine. Milk changes the size and taste, not the espresso caffeine number.
If an americano is made with a double shot, count it as 120-150 mg. Added hot water changes the volume, but the two espresso shots still set the caffeine range.
If a cappuccino uses one single shot, count 60-75 mg. If it uses a double shot, count 120-150 mg. The key detail is the number of 1 fl oz shots.
If a cafe calls a drink “double” but pulls two single shots, the answer is still 120-150 mg. If it uses only one 1 fl oz shot, it is not a double by this calculation.
Edge cases to watch
Do not estimate by cup size alone. A 12 fl oz latte may contain a double shot, while a 2 fl oz espresso is also a double. The caffeine comes from the espresso shots, not the final drink volume.
Do not compare ounce for ounce with brewed coffee. Espresso is concentrated: 1 fl oz gives 60-75 mg, while brewed coffee is listed per 8 fl oz at 80-100 mg.
For a fast answer: single espresso = 60-75 mg; double espresso = 120-150 mg. If the drink has two shots, use the double-shot range.
Caffeine in a double espresso
A double shot of espresso is typically 2 fl oz total and contains about 120-150 mg of caffeine. That comes from 2 single 1 fl oz shots, each listed at 60-75 mg.
| Espresso order | Volume | Caffeine |
|---|---|---|
| Single espresso | 1 fl oz | 60-75 mg |
| Double espresso | 2 fl oz | 120-150 mg |
| Two double espressos | 4 fl oz | 240-300 mg |
The most useful number to remember is about 120-150 mg per double. If a drink is made with a standard double shot, that caffeine estimate applies before adding milk, ice, water, or flavor syrup.
Worked examples
If you order a cappuccino made with a double shot, count it as 120-150 mg. The milk changes the size and taste of the drink, but it does not reduce the caffeine from the espresso.
If a latte uses one double shot, it is also 120-150 mg. A larger cup does not automatically mean more caffeine unless it includes more espresso shots.
If an iced Americano is made with a double shot plus water and ice, it still has 120-150 mg. Dilution changes strength on the tongue, not the caffeine total.
If you add an extra single shot to a double, the drink becomes three shots total. That works out to 180-225 mg, using 60-75 mg per 1 fl oz shot.
| Drink build | Math | Total caffeine |
|---|---|---|
| Double shot | 2 × 60-75 mg | 120-150 mg |
| Double plus 1 single | 3 × 60-75 mg | 180-225 mg |
| Two doubles | 4 × 60-75 mg | 240-300 mg |
How it compares with coffee and tea
A double espresso has more caffeine than a typical 8 fl oz brewed coffee at the low end, but overlaps at the high end. Brewed coffee is listed at 80-100 mg per 8 fl oz.
Compared with cold brew, a double espresso can be similar or lower. Cold brew is listed at 100-200 mg per 8 fl oz, while a double espresso is 120-150 mg.
A double espresso is usually stronger in caffeine than black tea. An 8 fl oz black tea has 40-70 mg, so a double espresso is roughly equal to about 2 to 3 black teas.
It is also much higher than green tea. An 8 fl oz green tea has 20-45 mg, so a double espresso can match about 3 to 6 green teas, depending on the exact cup.
Edge cases to count correctly
A “double” should mean 2 single shots, not simply a bigger cup. If the menu says double espresso, use 120-150 mg. If it says two doubles, use 240-300 mg.
A ristretto double is still commonly counted as a double espresso order for practical caffeine estimates. Without a listed ristretto figure, the usable estimate remains 120-150 mg.
A decaf espresso double cannot be calculated from the decaf coffee figure here, because the listed decaf value is for 8 fl oz decaf coffee, not espresso shots.
For fast counting: single espresso = 60-75 mg; double espresso = 120-150 mg; triple espresso = 180-225 mg; quad espresso = 240-300 mg.
How serving size changes caffeine
A single espresso shot is 1 fl oz and typically has 60-75 mg caffeine. A double shot is 2 fl oz made from two single shots, so it typically has 120-150 mg caffeine.
The key is that espresso caffeine scales by shot count, not by the size of the cup it is served in. Milk, ice, water, or foam can make the drink larger without adding caffeine.
| Espresso serving | Volume | 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 |
Worked examples by drink size
A 12 fl oz latte made with one espresso shot has the caffeine of one shot: 60-75 mg. The extra ounces are mostly milk, so they do not double the caffeine.
A 12 fl oz latte made with a double shot has 120-150 mg caffeine. It is the same caffeine as 2 fl oz of straight espresso, even though the finished drink is much larger.
A 16 fl oz iced latte with a double shot also has 120-150 mg caffeine. Ice and milk change the drinking volume, but not the espresso dose.
An Americano shows the same rule. A double-shot Americano may be 8, 12, or 16 fl oz after water is added, but the caffeine stays 120-150 mg if it contains two shots.
| Drink order | Espresso used | Finished size | Typical caffeine |
|---|---|---|---|
| Single espresso | 1 shot | 1 fl oz | 60-75 mg |
| Double espresso | 2 shots | 2 fl oz | 120-150 mg |
| Single-shot latte | 1 shot | 12 fl oz | 60-75 mg |
| Double-shot latte | 2 shots | 12 fl oz | 120-150 mg |
| Double-shot Americano | 2 shots | 16 fl oz | 120-150 mg |
How espresso compares with other servings
A double espresso at 120-150 mg is usually higher than an 8 fl oz brewed coffee at 80-100 mg, even though the coffee serving is four times larger by volume.
Compared with cold brew, the answer can overlap. An 8 fl oz cold brew typically has 100-200 mg caffeine, so it can be lower than, similar to, or higher than a double espresso.
A double espresso is also stronger than most 8 fl oz teas. Black tea has 40-70 mg, and green tea has 20-45 mg per 8 fl oz serving.
| Item | Typical serving | Typical caffeine |
|---|---|---|
| Double espresso | 2 fl oz | 120-150 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 |
| Energy drink | 8 fl oz | 70-100 mg |
Edge case: a “double” can be served in a demitasse cup, a cappuccino cup, or a tall iced drink. If it contains two 1 fl oz espresso shots, count it as 120-150 mg caffeine.
Another edge case is a split shot. If a barista pulls a double but uses only half in the drink, the drink has the caffeine of one shot: 60-75 mg.
If a menu lists “two shots” or “double espresso,” use 120-150 mg as the working estimate. If it lists “one shot,” use 60-75 mg, regardless of the cup size.
Single versus double shot caffeine
A single shot of espresso is 1 fl oz and typically has 60-75 mg of caffeine. A double shot is two single shots, so it typically has 120-150 mg of caffeine.
| Espresso amount | Volume | Typical caffeine |
|---|---|---|
| Single shot | 1 fl oz | 60-75 mg |
| Double shot | 2 fl oz | 120-150 mg |
The math is direct: 60 mg + 60 mg = 120 mg at the low end. At the high end, 75 mg + 75 mg = 150 mg. That is the usual caffeine range for a double espresso.
If a menu lists a drink as “double espresso,” expect about 2 fl oz of espresso and 120-150 mg caffeine. If the drink uses one double shot as its base, that same caffeine estimate applies.
Worked examples
Example 1: one single espresso in the morning equals about 60-75 mg caffeine. Ordering a double instead raises that to about 120-150 mg.
Example 2: two separate single espressos equal the same typical caffeine as one double espresso: 120-150 mg total.
Example 3: a latte made with a double shot has the espresso caffeine of that double shot: 120-150 mg. The added milk changes volume and taste, not the espresso caffeine total.
Example 4: an americano made with a double shot also starts at 120-150 mg caffeine. Added water dilutes strength per sip, but it does not remove caffeine.
How it compares with coffee and tea
An 8 fl oz brewed coffee typically has 80-100 mg caffeine. A double espresso, at 120-150 mg, usually has more caffeine than one typical 8 fl oz brewed coffee.
Two 8 fl oz brewed coffees would total 160-200 mg caffeine. That is more than a typical double espresso at 120-150 mg.
An 8 fl oz cold brew typically has 100-200 mg caffeine. A double espresso overlaps that range: 120-150 mg sits inside the cold brew range.
An 8 fl oz black tea has 40-70 mg caffeine. A double espresso has about as much caffeine as roughly two strong black teas, using 70 mg + 70 mg = 140 mg.
An 8 fl oz green tea has 20-45 mg caffeine. A double espresso at 120-150 mg is higher than even three 45 mg green teas, which total 135 mg at that upper tea figure.
Edge cases when the number seems off
If a cafe pulls a “double” as one basket instead of two separate singles, the caffeine estimate is still based on the served double: about 120-150 mg.
If a drink has two double shots, count it as four single shots. That gives a typical caffeine range of 240-300 mg.
If a drink has one single plus one double, count three single shots. That gives 180-225 mg caffeine.
Decaf espresso is not covered by the figures here. For decaf coffee, the listed reference is 8 fl oz decaf coffee at 2-15 mg, not an espresso shot amount.
How to estimate your shot
A double shot is usually 2 fl oz of espresso. Using the USDA/FDA figure of 60-75 mg per 1 fl oz single shot, estimate a double at 120-150 mg caffeine.
Quick calculation
- 1. Start with the serving size. Espresso is listed as 1 fl oz per single shot. A double is 2 single shots, so use 2 fl oz as your baseline.
- 2. Multiply the low end. One single shot has 60 mg at the low end. For a double: 60 × 2 = 120 mg.
- 3. Multiply the high end. One single shot has 75 mg at the high end. For a double: 75 × 2 = 150 mg.
- 4. Use the midpoint for a fast estimate. The midpoint of 60-75 mg is 67.5 mg per single shot. A double is about 135 mg.
- 5. Adjust only for actual volume. If your drink contains 1.5 fl oz of espresso, estimate 90-112.5 mg. If it contains 2.5 fl oz, estimate 150-187.5 mg.
- 6. Do not count milk or water. A latte, cappuccino, Americano, or flat white gets its caffeine from the espresso portion. Added milk or hot water changes volume, not caffeine.
Worked examples
Standard double espresso: 2 fl oz espresso. Estimate 120-150 mg, with 135 mg as a practical middle number.
Double latte: If the latte is made with 2 fl oz espresso plus milk, count only the espresso. Estimate 120-150 mg.
Double Americano: If it uses 2 fl oz espresso diluted with water, the caffeine stays 120-150 mg. The larger cup does not lower the total caffeine.
Short pull or split double: If you drink only 1 fl oz from a double-prepared espresso, estimate it like a single: 60-75 mg.
Extra-large espresso dose: If the drink has 3 fl oz espresso, treat it as 3 singles: 180-225 mg.
| Espresso amount | How to count it | Estimated caffeine |
|---|---|---|
| 1 fl oz | 1 single shot | 60-75 mg |
| 2 fl oz | Double shot | 120-150 mg |
| 3 fl oz | 3 single shots | 180-225 mg |
For comparison, a double espresso at 120-150 mg is above brewed coffee’s lower range of 80-100 mg per 8 fl oz, but below many 8 fl oz cold brews at 100-200 mg.
Caffeine compared with coffee
A double shot of espresso is 2 fl oz and typically has 120-150 mg of caffeine. That is more caffeine than a standard 8 fl oz brewed coffee at 80-100 mg, even though the espresso volume is only one-quarter as large.
| Drink | Serving size | Typical caffeine | Compared with a double espresso |
|---|---|---|---|
| Double espresso | 2 fl oz | 120-150 mg | Baseline |
| Brewed coffee | 8 fl oz | 80-100 mg | Double espresso has 20-70 mg more |
| Instant coffee | 8 fl oz | 30-90 mg | Double espresso has 30-120 mg more |
| Decaf coffee | 8 fl oz | 2-15 mg | Double espresso has 105-148 mg more |
| Cold brew | 8 fl oz | 100-200 mg | Can be lower, similar, or higher |
Double espresso vs 8 fl oz brewed coffee
Using the typical ranges, a double espresso at 120-150 mg beats an 8 fl oz brewed coffee at 80-100 mg. The smallest gap is 20 mg: 120 mg minus 100 mg.
The largest typical gap is 70 mg: 150 mg minus 80 mg. So if you switch from one regular 8 fl oz brewed coffee to a double espresso, expect roughly 20-70 mg more caffeine.
By volume, espresso is much more concentrated. A double espresso puts 120-150 mg into 2 fl oz. Brewed coffee puts 80-100 mg into 8 fl oz, so the cup has more liquid but less caffeine.
Worked coffee-shop examples
If your usual order is one 8 fl oz brewed coffee at 80-100 mg, one double espresso at 120-150 mg adds 20-70 mg compared with that cup.
If you drink two 8 fl oz brewed coffees, the total is 160-200 mg. That is more than one double espresso, which is 120-150 mg, by 10-80 mg.
If you drink one double espresso plus one 8 fl oz brewed coffee, the total is 200-250 mg. That comes from 120-150 mg plus 80-100 mg.
If a latte or cappuccino is made with a double shot, count the espresso portion as 120-150 mg. The milk changes the drink size, not the caffeine from the espresso.
Edge cases: instant, decaf, and cold brew
Compared with instant coffee, a double espresso is usually stronger. Instant coffee has 30-90 mg per 8 fl oz, so a double espresso has 30-120 mg more.
Compared with decaf coffee, the difference is large. An 8 fl oz decaf has 2-15 mg, while a double espresso has 120-150 mg. That is 105-148 mg more.
Cold brew is the main exception. An 8 fl oz cold brew has 100-200 mg. A double espresso can be higher than a 100 mg cold brew, but lower than a 200 mg cold brew.
At the overlap, 120-150 mg from a double espresso sits inside the cold brew range. So “espresso has more caffeine than coffee” is true for standard brewed coffee, but not always for cold brew.
Frequently Asked Questions
How much caffeine is in a double shot of espresso?
A double shot of espresso has about 120 to 150 mg of caffeine. That is based on 2 single 1 fl oz espresso shots, with each single shot typically containing 60 to 75 mg of caffeine.
Is a double shot of espresso more caffeine than regular coffee?
Usually, yes for a standard comparison. A double espresso has about 120 to 150 mg caffeine, while an 8 fl oz brewed coffee typically has 80 to 100 mg. Per ounce, espresso is much stronger, even though the serving is smaller.
How much caffeine is in 2 shots of espresso at a coffee shop?
Two espresso shots typically contain 120 to 150 mg of caffeine total. A single 1 fl oz shot is usually 60 to 75 mg, so a standard double doubles that amount. Actual café drinks can vary by coffee and extraction.
Is a double shot of espresso the same as two cups of coffee?
No. A double espresso is about 2 fl oz and contains 120 to 150 mg caffeine. Two 8 fl oz cups of brewed coffee would typically contain 160 to 200 mg caffeine total, using the 80 to 100 mg range per cup.
How does a double espresso compare with cold brew or energy drinks?
A double espresso has about 120 to 150 mg caffeine. An 8 fl oz cold brew typically has 100 to 200 mg, so it can be lower or higher. An 8 fl oz energy drink typically has 70 to 100 mg, usually less than a double espresso.
