Starbucks Doubleshot caffeine isn’t listed in the provided USDA/FDA reference data. For comparison, a single 1 fl oz espresso shot typically has 60-75 mg caffeine; an 8 fl oz brewed coffee has 80-100 mg.
How Much Caffeine In Starbucks Doubleshot: a Starbucks Doubleshot Espresso drink typically has about 120-150 mg of caffeine because it is based on two espresso shots, and one 1 fl oz espresso shot is typically 60-75 mg.
That puts a Doubleshot above an 8 fl oz brewed coffee at 80-100 mg, above black tea at 40-70 mg, and below many 8 fl oz cold brews at 100-200 mg. Size and recipe changes can shift the total.
The Short Answer, With Numbers
A Starbucks “Doubleshot” made as two espresso shots is best estimated at 120-150 mg caffeine, using the reference figure of 60-75 mg per 1 fl oz espresso shot.
The math is direct: 2 shots × 60-75 mg = 120-150 mg. That is the number to use if you mean a double espresso-style Starbucks drink.
| Drink or ingredient | Typical serving | Caffeine range | How it applies to a Doubleshot |
|---|---|---|---|
| Espresso | 1 fl oz single shot | 60-75 mg | Two shots = 120-150 mg |
| Energy drink | 8 fl oz | 70-100 mg | Useful only for bottled “energy” comparisons |
| Brewed coffee | 8 fl oz | 80-100 mg | A double shot is higher than a typical 8 fl oz brewed coffee |
| Cold brew | 8 fl oz | 100-200 mg | A double shot overlaps the middle of this range |
If You Mean Two Espresso Shots
Use 120-150 mg. One espresso shot is 60-75 mg, so a true double is simply twice that amount.
Worked example: if each shot is at the low end, 60 mg + 60 mg = 120 mg. If each shot is at the high end, 75 mg + 75 mg = 150 mg.
That makes a two-shot Doubleshot stronger than a typical 8 fl oz brewed coffee, which is 80-100 mg caffeine.
It is also far stronger than 8 fl oz decaf coffee, which is only 2-15 mg, but decaf is not the right comparison for a standard espresso-based Doubleshot.
If You Mean a Bottled Starbucks Doubleshot-Style Energy Drink
The reference data does not give a Starbucks bottled Doubleshot figure. Do not assume the espresso-shot number applies to every canned or bottled product.
For a generic comparison only, an 8 fl oz energy drink is listed at 70-100 mg. That is lower than the 120-150 mg estimate for two espresso shots.
If the container is larger than 8 fl oz, the only precise answer comes from the product label. The reference energy-drink number is for 8 fl oz, not for every can size.
Quick Comparisons
A double espresso estimate of 120-150 mg is about 1.5 to 1.9 times the low end of brewed coffee at 80 mg.
Against the high end of brewed coffee, 150 mg is 50 mg more than a typical 8 fl oz brewed coffee at 100 mg.
Compared with cold brew, the double shot falls inside the cold brew range. Cold brew is listed at 100-200 mg per 8 fl oz, so some cold brews are lower and some are higher.
Compared with black tea at 40-70 mg per 8 fl oz, a 120-150 mg Doubleshot is roughly equal to about two strong cups of black tea.
Compared with cola at 30-40 mg per 12 fl oz, a two-shot Doubleshot has about 3 to 5 cola servings worth of caffeine, depending on where each falls in its range.
Starbucks Doubleshot caffeine amount
A Starbucks Doubleshot made as 2 espresso shots contains about 120-150 mg caffeine, using the reference value of 60-75 mg per 1 fl oz espresso shot.
That number applies when “Doubleshot” means two single espresso shots. The caffeine math is simple: 2 × 60-75 mg = 120-150 mg.
Quick caffeine estimate
| Drink basis | Serving used | Caffeine per serving | 2-serving total |
|---|---|---|---|
| Espresso | 1 fl oz single shot | 60-75 mg | 120-150 mg |
If your Starbucks Doubleshot is espresso-based, use 120-150 mg as the practical caffeine range.
The low end, 120 mg, comes from two 60 mg espresso shots. The high end, 150 mg, comes from two 75 mg espresso shots.
Worked examples
Example 1: one Doubleshot using two standard espresso shots: 60 mg + 60 mg = 120 mg at the low end.
Example 2: one Doubleshot using two stronger espresso shots: 75 mg + 75 mg = 150 mg at the high end.
Example 3: half of a 2-shot drink would be about 60-75 mg, because that equals one 1 fl oz espresso shot.
Example 4: two Doubleshots would be about 240-300 mg, because 4 espresso shots equal 4 × 60-75 mg.
How it compares with other caffeinated drinks
| Drink | Typical serving | Caffeine |
|---|---|---|
| Starbucks Doubleshot, espresso basis | 2 single espresso shots | 120-150 mg |
| Brewed coffee | 8 fl oz | 80-100 mg |
| Cold brew | 8 fl oz | 100-200 mg |
| Energy drink | 8 fl oz | 70-100 mg |
| Black tea | 8 fl oz | 40-70 mg |
| Cola | 12 fl oz | 30-40 mg |
A 2-shot Doubleshot has more caffeine than a typical 8 fl oz brewed coffee at 80-100 mg.
It overlaps with cold brew. An 8 fl oz cold brew is listed at 100-200 mg, so a 120-150 mg Doubleshot sits in the middle of that range.
Compared with an 8 fl oz energy drink at 70-100 mg, a 2-shot Doubleshot is higher by about 20-80 mg, depending on the espresso strength.
Edge cases to watch
If the drink is not actually two espresso shots, the number changes. Count shots first, then multiply by 60-75 mg per shot.
A single-shot version would be 60-75 mg. A triple-shot version would be 180-225 mg. A four-shot version would be 240-300 mg.
If “Doubleshot” refers to a bottled or canned ready-to-drink product, this reference data does not give a specific label value. Use the package’s caffeine statement for that exact product.
For a menu espresso Doubleshot, the answer is about 120-150 mg caffeine.
Caffeine by can size
Use the can’s fluid ounces first. Without the product’s exact label value, the defensible estimate is by drink type: coffee, espresso, cold brew, or energy-drink style.
For a Starbucks Doubleshot-style canned coffee, the most relevant reference ranges are brewed coffee, espresso, cold brew, and energy drink. The numbers below scale those ranges to common can sizes.
Estimated caffeine ranges by can volume
| Can size | If like brewed coffee | If like cold brew | If like energy drink | If based on espresso shots |
|---|---|---|---|---|
| 6.5 fl oz | 65-81 mg | 81-163 mg | 57-81 mg | 120-150 mg for 2 shots |
| 8 fl oz | 80-100 mg | 100-200 mg | 70-100 mg | 120-150 mg for 2 shots |
| 11 fl oz | 110-138 mg | 138-275 mg | 96-138 mg | 120-150 mg for 2 shots |
| 15 fl oz | 150-188 mg | 188-375 mg | 131-188 mg | 120-150 mg for 2 shots |
The espresso-shot column is different from the volume columns. A single 1 fl oz espresso is 60-75 mg, so “double shot” math is 2 × 60-75 mg = 120-150 mg.
That 120-150 mg estimate applies only if the can’s caffeine mainly comes from two espresso shots. A larger can can still have the same espresso caffeine if it is diluted with milk, water, sugar, or flavoring.
For a 6.5 fl oz can, two-shot espresso math gives 120-150 mg. By contrast, a brewed-coffee strength estimate for 6.5 fl oz is only 65-81 mg.
That gap matters. A small can labeled around a “double shot” may be stronger per ounce than a plain coffee drink, even if the can looks smaller than an 8 fl oz coffee serving.
Worked examples
Example 1: if the can is 6.5 fl oz and behaves like brewed coffee, calculate 6.5 ÷ 8 × 80-100 mg. Result: about 65-81 mg.
Example 2: if the can is 6.5 fl oz but is truly two espresso shots, calculate 2 × 60-75 mg. Result: 120-150 mg.
Example 3: if the can is 15 fl oz and matches an energy drink, calculate 15 ÷ 8 × 70-100 mg. Result: about 131-188 mg.
Example 4: if the 15 fl oz can is closer to cold brew strength, calculate 15 ÷ 8 × 100-200 mg. Result: about 188-375 mg.
The edge case is decaf-style coffee. An 8 fl oz decaf coffee is 2-15 mg, so a 6.5 fl oz decaf-strength can would scale to about 2-12 mg.
Dark chocolate additions are usually minor compared with coffee. A full 1 oz of dark chocolate contributes 10-25 mg, but many coffee cans use flavoring, not a full ounce of chocolate.
Fast answer: for a small “Doubleshot” can, the practical two-espresso-shot estimate is 120-150 mg caffeine. For larger coffee-energy cans, use the can-size table unless the label gives an exact mg amount.
How to check the label
For Starbucks Doubleshot, use the caffeine number printed on the can, bottle, carton, or product page when available. Do not estimate from the word “double”; the actual caffeine depends on serving size and formula.
Label-check steps
- 1. Find the exact product name. Check whether it says Doubleshot, Doubleshot Energy, espresso drink, or another variant. Similar-looking cans can have different caffeine amounts, so match the full name and flavor.
- 2. Confirm the serving size. Look for ounces first. Caffeine comparisons only make sense by volume. The reference serving for brewed coffee is 8 fl oz, espresso is 1 fl oz, and cola is 12 fl oz.
- 3. Look for “caffeine” in milligrams. Some labels or brand pages state “contains ___ mg caffeine.” Use that number as the answer for that package or serving. If it is absent, do not calculate it from coffee content.
- 4. Check whether the number is per can or per serving. If a container lists 2 servings and gives caffeine per serving, multiply by 2 for the whole container. If it says caffeine per can, do not multiply.
- 5. Convert to an 8 fl oz comparison. Use this formula: listed caffeine ÷ container ounces × 8. Example: if a 15 fl oz can lists 150 mg, then 150 ÷ 15 × 8 = 80 mg per 8 fl oz.
- 6. Compare it with common drinks. Brewed coffee is typically 80-100 mg per 8 fl oz. Espresso is 60-75 mg per 1 fl oz shot. Cold brew is 100-200 mg per 8 fl oz. Energy drinks are 70-100 mg per 8 fl oz.
- 7. Recheck multipacks and imported cans. A case may mix old and new label designs, and regional labels can differ. Use the caffeine statement on the individual can you will drink, not the box photo.
Worked examples
If the label says 120 mg caffeine per 11 fl oz can, the whole can has 120 mg. Per 8 fl oz, that is 120 ÷ 11 × 8 = 87 mg, close to brewed coffee’s 80-100 mg range.
If the label says 90 mg per serving and the can has 2 servings, the full can has 180 mg. That is higher than a typical 8 fl oz energy drink range of 70-100 mg.
If the label says 75 mg per serving and the bottle is one serving, that is similar to the upper end of a single 1 fl oz espresso shot, which is 60-75 mg.
| Drink | Reference serving | Caffeine range |
|---|---|---|
| Brewed coffee | 8 fl oz | 80-100 mg |
| Espresso | 1 fl oz | 60-75 mg |
| Cold brew | 8 fl oz | 100-200 mg |
| Energy drink | 8 fl oz | 70-100 mg |
| Cola | 12 fl oz | 30-40 mg |
Edge case: if the label lists coffee, espresso, guarana, or added caffeine but gives no milligrams, the package does not provide a precise answer. Use only a manufacturer caffeine statement for that exact product.
Compared with regular coffee
A Starbucks Doubleshot built around 2 espresso shots lands at about 120-150 mg of caffeine, using the standard espresso range of 60-75 mg per 1 fl oz shot.
Regular brewed coffee is lower per typical serving: an 8 fl oz cup has about 80-100 mg. So a 2-shot Doubleshot has roughly 20-70 mg more caffeine than an 8 oz brewed coffee.
Quick side-by-side
| Drink | Typical serving | Caffeine | Compared with 2 espresso shots |
|---|---|---|---|
| Starbucks Doubleshot-style 2 espresso shots | 2 fl oz espresso | 120-150 mg | Baseline |
| Brewed coffee | 8 fl oz | 80-100 mg | 20-70 mg less |
| Instant coffee | 8 fl oz | 30-90 mg | 30-120 mg less |
| Cold brew | 8 fl oz | 100-200 mg | Could be 50 mg less to 80 mg more |
| Decaf coffee | 8 fl oz | 2-15 mg | 105-148 mg less |
Worked example: compare the low end. Two espresso shots at 120 mg versus brewed coffee at 80 mg gives a 40 mg difference.
Worked example: compare the high end. Two espresso shots at 150 mg versus brewed coffee at 100 mg gives a 50 mg difference.
The widest brewed-coffee comparison is 120-150 mg versus 80-100 mg. That means the Doubleshot-style drink is about 1.2 to 1.9 times an 8 oz brewed coffee.
What if your “regular coffee” is bigger?
If you drink 16 fl oz of brewed coffee, double the 8 oz range: 160-200 mg. That larger coffee can exceed a 2-shot Doubleshot by 10-80 mg.
If your regular coffee is only 6 fl oz, scale the 8 oz range down. Six ounces is three-quarters of 8 oz, so brewed coffee is about 60-75 mg.
Against that 6 oz cup, a 2-shot Doubleshot at 120-150 mg is roughly double: 45-90 mg more.
Edge cases that change the comparison
Cold brew can flip the result. An 8 oz cold brew has 100-200 mg, so it may be lower than, equal to, or higher than a 2-shot Doubleshot.
Instant coffee is usually weaker than the 2-shot number. At 30-90 mg per 8 oz, it can have only one-quarter to three-quarters as much caffeine.
Decaf is not caffeine-free. An 8 oz decaf coffee has 2-15 mg, but a 2-shot Doubleshot has about 8 to 75 times more caffeine.
Bottom line: compared with an 8 oz brewed coffee, a Starbucks Doubleshot-style 2-espresso drink is typically stronger, at 120-150 mg versus 80-100 mg.
Who should limit intake
Limit a Starbucks Doubleshot if you are sensitive to caffeine, stacking it with other caffeinated drinks, or using it late in the day. The exact amount depends on the package, so check the label first.
For scale, 1 fl oz of espresso typically has 60-75 mg caffeine. An 8 fl oz brewed coffee has 80-100 mg. An 8 fl oz energy drink has 70-100 mg.
People who should be most cautious
- Caffeine-sensitive adults: If 1 cup of brewed coffee makes you jittery, a Doubleshot may be too much, especially if it contains espresso plus added coffee ingredients.
- People with sleep trouble: If caffeine affects your sleep, count every source: coffee, tea, cola, energy drinks, chocolate, and the Doubleshot.
- People avoiding stimulant spikes: Espresso is concentrated: 1 fl oz can supply 60-75 mg, close to an 8 fl oz energy drink at 70-100 mg.
- Anyone drinking multiple cans: Two servings can turn a moderate caffeine choice into the caffeine range of several standard drinks.
- Teens and smaller adults: A single espresso-style drink can feel stronger than the same caffeine spread across a larger coffee.
Worked examples for counting caffeine
If your Doubleshot label lists caffeine, use that number. Then add anything else you drank. If the label is unavailable, compare it to espresso: one single shot is typically 60-75 mg.
Example 1: you drink a Doubleshot plus one 8 fl oz brewed coffee. The brewed coffee adds 80-100 mg. Add the label number from the can to get your day’s total.
Example 2: you drink a Doubleshot with lunch and a 12 fl oz cola later. The cola adds 30-40 mg. That small soda still matters when combined with espresso-based caffeine.
Example 3: you drink a Doubleshot, then an 8 fl oz energy drink. The energy drink adds 70-100 mg, similar to or more than a single espresso shot.
Example 4: you also eat 1 oz dark chocolate. Add another 10-25 mg. Chocolate is not a major source, but it can push a sensitive person over their comfort point.
Edge cases that change the answer
Do not assume “coffee” means one strength. Brewed coffee is 80-100 mg per 8 fl oz, instant coffee is 30-90 mg, and cold brew is 100-200 mg per 8 fl oz.
Decaf is not caffeine-free. An 8 fl oz decaf coffee still has 2-15 mg. That is small, but relevant if you are trying to keep intake extremely low.
Tea counts too. An 8 fl oz black tea has 40-70 mg, while green tea has 20-45 mg. A Doubleshot plus tea can equal more caffeine than expected.
| Item to add to a Doubleshot | Typical caffeine added |
|---|---|
| 1 fl oz espresso | 60-75 mg |
| 8 fl oz brewed coffee | 80-100 mg |
| 8 fl oz cold brew | 100-200 mg |
| 12 fl oz cola | 30-40 mg |
