Starbucks Doubleshot Energy Mocha Review: The Canned Coffee That Actually Tastes Like Coffee

Here’s the thing about canned energy coffee drinks: most of them taste like someone blended a battery with instant coffee and called it a day. The Starbucks Doubleshot Energy in Mocha is not that. It’s the rare shelf-stable option that drinks like a legitimate iced mocha, not a chemistry experiment.

What You’re Actually Getting

Each 15-fluid-ounce can delivers 135mg of caffeine. To put that in perspective, that’s roughly the same as a tall (12oz) Starbucks brewed coffee, but you’re getting an extra 3 ounces of volume. The can itself is slim and tall — it fits standard car cup holders without wobbling, which matters more than you’d think.

The ingredient list is where this diverges from your standard energy drink. You’re getting brewed Starbucks coffee as the base, plus the typical energy drink additions: guarana, ginseng, and B-vitamins. The mocha flavor comes from cocoa and natural flavors — no artificial coloring, which is rare in this category.

Real-World Performance

I tested this the way most people actually drink it: straight from the fridge, poured over ice, and — let’s be honest — sometimes at room temperature in a hurry. The flavor holds up in all three scenarios.

The mocha profile is balanced. It’s not a sugar-bomb hot chocolate pretending to be coffee. You get the roasted coffee bitterness up front, then the chocolate sweetness rounds it out. The carbonation is subtle — more like a sparkling cold brew than a soda. If you’re expecting the aggressive fizz of a Monster, you’ll be disappointed. If you want something that still reads as coffee, this is it.

One thing I genuinely appreciate: the can doesn’t need to be shaken before opening. There’s no sediment settling at the bottom, no chalky residue. Every sip tastes the same as the first.

What Buyers Keep Saying

Scrolling through the 229 ratings, the same themes keep popping up. “Tastes like a real mocha, not a chemical energy drink” is a recurring sentiment. Another buyer noted, “This is the only energy coffee I’ve tried that doesn’t leave that weird metallic aftertaste.”

The consistency is also a frequent praise point. Multiple reviewers mention buying it in bulk for travel or keeping a case in the office fridge. One buyer summed it up: “Perfect middle ground between my morning coffee and my afternoon energy drink.”

The Honest Shortcomings

Let’s not pretend this is perfect. At 19 grams of sugar per can, this isn’t a daily habit for anyone watching their intake. The 15oz size is also slightly smaller than the 16oz standard for energy drinks — it’s a minor difference, but noticeable if you’re used to a full 16.

The biggest criticism in the reviews is the price per can when bought single at convenience stores. However, buying by the 12-pack on Amazon drops the per-can cost significantly, which is how most regular buyers seem to purchase it.

Who Should Buy This

• The commuter who wants one drink that covers both coffee and energy needs — this replaces two stops
• The iced coffee loyalist who’s tired of watery gas station mochas
• The traveler who wants reliable caffeine without hunting for a Starbucks in an airport

Skip it if you need a high-fizz energy drink, or if you’re strict about sugar content — the full-sugar mocha is the only widely available option.

FAQ

Q: Is this actually coffee or a coffee-flavored energy drink? A: It’s brewed Starbucks coffee as the base, with energy ingredients added. It’s not just caffeine + flavoring — you’re genuinely getting coffee.

Q: How does the caffeine compare to a regular Starbucks drink? A: 135mg per can, which is comparable to a tall brewed coffee. For reference, a standard 8oz Red Bull has 80mg.

Q: Does it need to be refrigerated? A: No. It’s shelf-stable, but it tastes significantly better chilled. If it’s been in your car for a week, drink it warm at your own risk — not for the flavor, but for the experience.

The Verdict

Buy it if you want a canned coffee that actually tastes like a coffee shop mocha, with a caffeine kick that bridges the gap between your morning brew and afternoon slump. Skip it if you need aggressive carbonation or a sugar-free option.

This is one of the few products in its category that earns its 4.6-star rating honestly. It’s not gourmet, but it’s consistently good — and for a shelf-stable energy coffee, that’s the highest compliment.
