How Much Caffeine in a Starbucks Doubleshot Energy?

The Short Answer 

Let’s get straight to it. A 15-ounce Starbucks Double Shot Canned Espresso has 135 mg of caffeine. A regular in-store double shot has 150 mg, while a double shot over ice has a whopping 225 mg of caffeine. So, if you want the most caffeine content, go with the iced version.

Comparing Starbucks Doubleshot Caffeine 

Why is it that all 3 of Starbucks Doubleshot drinks vary wildly when it comes to caffeine content? The answer lies in the way they’re served. It’s a little more complicated than you may think, but we’ll do our best to explain.

Starbucks Double Shot Canned Espresso 

You’ll find the canned version of a double shot at your local Starbucks, gas station, grocery store, or online. However, Starbucks offers two different kinds of Doubleshot canned drinks: 

• Doubleshot Energy 
• Doubleshot Espresso 

A 15-ounce can of Doubleshot Energy contains brewed coffee, guarana, B vitamins, ginseng, and 135 mg of caffeine. A 6.5 ounce can of the espresso version contains espresso, sugar, milk, cream, and 120 mg of caffeine. While they’re similar in caffeine content, the Doubleshot Espresso is more concentrated.

Starbucks Double Shot In-Store Espresso

If you’re ordering your drink at your local Starbucks, a double shot is exactly as it sounds – two shots of espresso. You can order this drink as a latte version or plain. Either way, the double shot will have 150 mg of caffeine, offering more caffeine than either canned option. And, if you order the plain version, you’re looking at a 2-ounce shot, making it very concentrated.

Starbucks Double Shot In-Store Espresso Over Ice

Enjoy iced coffee? You can also order your double shot over ice. If you’re looking for the most perks, this is the way to go. This Doubleshot offers a whopping 225 mg of caffeine. The recommended caffeine daily intake is 400 mg, so this Doubleshot alone is over half of your recommended daily dose. 

Can You Make This Drink at Home? 

Absolutely! Several Starbucks copycat recipes will allow you to recreate your favorite signature drinks at home. However, keep in mind that the caffeine content of your Doubleshot will vary depending on the ingredients you use.

Here is how you’d make a tall Starbucks double shot espresso over ice:  

1. Gather Your Ingredients. You’ll need 2 shots of espresso, 2 tablespoons of simple syrup, an ounce of creamer or milk of your choice.

3. Add Simple Syrup. Add your syrup to the cocktail shaker and shake vigorously for 30 seconds.
