You may think you know what a doubleshot is, but it’s not always two shots of espresso. Starbucks offers a lot of doubleshot drinks — and their caffeine content varies wildly!
So which doubleshot drink will get you the most caffeine for your dollar, and what’s the difference between all of these offerings? We’ll unravel this Starbucks mystery for you.
Starbucks Doubleshot Caffeine
Starbucks offers three basic types of doubleshot drinks: canned doubleshots, hot espresso double shots, and doubleshots on ice. These drinks all contain two shots of espresso — in theory — but their caffeine content varies a lot more than you might think.
How Much Caffeine is in Starbucks Doubleshot Energy Drinks (Canned)?
But wait! It’s even more complicated than that: Starbucks offers two different kinds of canned Doubleshot drinks: Doubleshot Energy and Doubleshot Espresso. The energy version contains brewed coffee, along with guarana, ginseng, and B vitamins. The espresso version contains espresso, milk, sugar, and cream.
You’ll find this Starbucks offering at convenience stores, grocery stores, and online. They’re pretty similar in caffeine content, though the espresso version is much more concentrated. A 15-ounce can of Starbucks Doubleshot energy has 135 milligrams of caffeine, while a 6.5-ounce can of Doubleshot espresso has 120 milligrams of caffeine.
How Much Caffeine in Starbucks Doubleshot Espresso (In-Store)?
If you’re buying coffee at a Starbucks, the basic version of a double shot is two shots of espresso. Whether you order this in a latte or plain, your double shot of espresso will have 150 milligrams of caffeine — putting it above either canned version. Plus, at only around 2 ounces, the espresso double shot is highly concentrated!
How Much Caffeine in Starbucks Doubleshot on Ice (In-Store)?
If you’re looking to maximize your caffeine intake, ordering a Doubleshot on Ice is the way to go. This iced coffee drink is much more caffeinated than any other Starbucks doubleshot, coming in at an impressive 225 milligrams of caffeine. For reference, that’s over half your recommended daily caffeine intake (400 milligrams), and it’s almost 2.5 times more caffeinated than a regular cup of coffee (95 milligrams).
The Bottom Line
So how much caffeine is in a Starbucks Doubleshot? As you’ve seen, it’s a little complicated. If you buy a canned Doubleshot, you’ll drink between 120 and 135 milligrams of caffeine. If you order a double shot of espresso at a Starbucks coffee shop, you’ll drink about 150 milligrams of caffeine. And if you order a Doubleshot on Ice, you’ll end up with 225 milligrams of caffeine — making it one of the most caffeinated drinks available at Starbucks!
Clearly, a double shot isn’t as simple as two shots of espresso. We hope this guide helps you untangle one of Starbucks’ many mysteries — or just enjoy your espresso drink a little more!
