How Much Caffeine Is In A Starbucks Doubleshot Can?

A 15-fluid-ounce can of Starbucks Doubleshot Energy contains 135 mg of caffeine, according to official PepsiCo product facts.

Grab a can of Doubleshot Energy from a convenience store cooler, and the label might not immediately tell you what you’re getting. Is it a coffee drink with an energy boost? Or is it closer to a can of Monster? The question of how much caffeine is inside matters if you’re watching your intake for sleep, blood pressure, or just tracking how much you’ve had before lunch.

The answer depends on which can you pick up. The most common 15-ounce version of Starbucks Doubleshot Energy (Vanilla, Mocha, or Caramel) contains 135 mg of caffeine. That puts it somewhere between a standard cup of brewed coffee and a full-strength energy drink. For most healthy adults, that’s well within the generally advised daily range, but it’s helpful to know exactly where it lands.

Where The Caffeine In A Doubleshot Can Comes From

Starbucks Doubleshot Energy isn’t brewed in the same way as the coffee you’d order at a Starbucks counter. It’s classified as a fortified energy coffee beverage and is made with Starbucks Arabica coffee as its primary ingredient — specifically water and coffee extract. The caffeine comes from that coffee base, not from added synthetic sources.

On top of that coffee foundation, the drink also includes 1,135 mg of taurine, 120 mg of panax ginseng, 90 mg of guarana, and 3.4 mg of riboflavin. Guarana itself naturally contains caffeine, so it contributes a small amount to the total. Still, the primary source remains the coffee extract.

A 15-ounce can also carries 210 calories, which is worth noting if you’re drinking it as an afternoon pick-me-up rather than a meal. The calorie load comes mostly from cream and sugar, making it more of a treat than a straight black coffee.

Why The Can Size Matters More Than You Think

People often assume a single can of any coffee drink equals a single serving of caffeine. But the Doubleshot line comes in several sizes, and the caffeine content changes with the volume.

• 15 fl oz Doubleshot Energy (Vanilla, Mocha, Caramel): 135 mg of caffeine. This is the standard can you’ll see most often, and it’s the figure backed by the official PepsiCo product facts.
• 6.5 fl oz Doubleshot Espresso & Cream: Approximately 120 mg of caffeine, according to Caffeine Informer. That’s a much smaller can with almost as much caffeine per ounce.
• 11 fl oz Doubleshot Energy (speculative): The official PepsiCo page does not list a caffeine figure for this size, so it’s best not to assume. Stick with the 15 oz figure as the reliable anchor.
• Zero Sugar Doubleshot Energy: The caffeine content for this variant is not confirmed by a source in available data, though it’s likely similar to the regular version. Check the label directly.

The key takeaway: if you’re comparing caffeine intake, look at the can size first. A small Espresso & Cream drink packs dense caffeine for its volume, while the larger Energy can spreads a moderate dose across more fluid.

How It Compares To Other Coffee And Energy Drinks

To put 135 mg of caffeine into context, compare it with what you might otherwise drink in a morning. A 12 oz (tall) cup of brewed Starbucks coffee contains 235–290 mg of caffeine, according to the Center for Science in the Public Interest’s caffeine chart. That’s roughly 1.7 to 2.1 times the amount in a full can of Doubleshot Energy.

A double shot of Starbucks espresso (2 oz) has about 150 mg of caffeine, which is slightly more than the Doubleshot can. Corner Coffee Store’s compared to espresso double shot article, the difference is modest: one espresso shot gives you a more concentrated hit, while the Doubleshot spreads it out over a larger volume.

A standard 8 oz cup of home-brewed coffee typically contains 80–100 mg of caffeine. So the Doubleshot Energy has roughly 35–55 mg more than your average mug. And compared to a 16 oz Monster Original at 160 mg, the Doubleshot comes in 25 mg lower — close, but not quite at energy-drink levels. If you were drinking a Monster, switching to a Doubleshot would slightly lower your caffeine per can.

The table above uses figures from the official PepsiCo product facts, CSPI, and Caffeine Informer. Individual brewing methods and coffee bean variations can shift these numbers slightly, but the Doubleshot Energy’s 135 mg figure is a reliable benchmark for its specific product.

How Many Doubleshot Cans Fit Into A Daily Caffeine Limit

Health authorities generally consider up to 400 mg of caffeine per day safe for most healthy adults, as noted by the Mayo Clinic’s safe daily caffeine limit page. Doing the math, that means a healthy adult could drink about three 15-ounce cans of Doubleshot Energy and still stay under the typical 400 mg threshold.

Individual factors adjust that number. Caffeine may cause a brief, temporary rise in blood pressure, especially in people who don’t consume it regularly. If you have high blood pressure or are sensitive to caffeine, you might aim for less than the 400 mg cap. For pregnant individuals, the recommended maximum is often lower — around 200 mg per day. That would mean one Doubleshot Energy can (135 mg) fits within that limit, but adding more caffeine from other sources could push you over.

Medications, body size, and sleep quality also affect your personal tolerance. A healthy metabolism can clear caffeine within a few hours, but some people find that even moderate amounts disrupt their sleep if consumed late in the day.

Reading The Label Before You Buy

PepsiCo’s product facts page confirms that all three core flavors of the 15 oz Doubleshot Energy — Vanilla, Mocha, and Caramel — share the same 135 mg caffeine content. The Mocha variant is not higher in caffeine despite its chocolate association; it’s simply a flavor difference.

If you’re looking for a lower-caffeine option, the standard 8 oz cup of brewed coffee or a single shot of espresso gives you around 80–150 mg. If you want more, a Tall brewed Starbucks coffee nearly doubles the caffeine of the Doubleshot can. Knowing those benchmarks helps you pick what fits your day.

The information above comes directly from the manufacturer’s product facts. If you see an online claim suggesting a different figure (like 146 mg from some blogs), the PepsiCo number is the most authoritative for the specific 15 oz can.

The Bottom Line

A Starbucks Doubleshot Energy can delivers 135 mg of caffeine in a convenient 15-ounce package. That’s less than a tall brewed Starbucks coffee or a double espresso, slightly more than a standard 8 oz cup of home-brewed coffee, and about 25 mg under a typical Monster energy drink. For most healthy adults, it fits comfortably within the daily recommended limit — but your personal tolerance, any medications you take, and whether you’re pregnant can adjust that equation.

For pregnant readers, checking with your obstetrician or midwife about whether 135 mg fits well alongside other caffeine sources you consume that day is worth a conversation, since individual thresholds vary during pregnancy.
