The Short Answer: It Depends on the Product
The question of whether Starbucks Doubleshot Energy or Monster has more caffeine is more nuanced than a simple yes or no. For a direct comparison between the most common products—Original Monster and a standard canned Starbucks Doubleshot Energy—Monster usually holds the lead. However, the Starbucks lineup includes more potent options, including certain Doubleshot and Tripleshot formulas, that can easily surpass the caffeine content of a standard Monster can.
Head-to-Head: Standard Doubleshot vs. Original Monster
Caffeine Content Comparison
When comparing the flagship products of each brand, the numbers show a clear difference. The Original Green Monster Energy drink, sold in a 16 fl oz can, consistently contains 160 mg of caffeine. In contrast, a 15 fl oz can of standard Starbucks Doubleshot Energy (such as Vanilla or Mocha flavors) typically lists 135 mg of caffeine. This makes the standard Monster the more caffeinated option on a per-can basis.
Other Ingredients to Consider
Beyond caffeine, the ingredient lists of these drinks also differ significantly. Monster Energy is built around a proprietary "energy blend" that includes taurine, L-carnitine, ginseng, and B vitamins, along with a high sugar content in its original formulation. The Starbucks Doubleshot Energy combines its signature brewed coffee with milk, sugar, and a similar blend of additives like guarana, ginseng, and B vitamins. The presence of these additional stimulants in both drinks can contribute to the perceived energy boost, though scientific evidence on their additional efficacy beyond caffeine is limited.
The Caffeine Heavyweights: Stronger Starbucks Options
The "Strong Coffee" Doubleshot
Starbucks has specific canned Doubleshot products labeled for "Strong Coffee" that deliver a much more powerful punch. A 15 fl oz can of Starbucks Doubleshot Energy Vanilla, Strong Coffee, for example, is advertised to contain an impressive 225 mg of caffeine. This places it significantly higher than the standard 160 mg found in a can of Original Monster, flipping the comparison on its head.
The Tripleshot Offering
For those seeking an even more intense coffee energy drink, Starbucks also offers its Tripleshot line. An 11 fl oz can of Starbucks Tripleshot Energy boasts 165 mg of caffeine, exceeding the original Monster's content. This confirms that Starbucks offers multiple canned products with a higher caffeine load than the most well-known Monster drink.
Beyond the Numbers: What Influences the Jolt?
It is important to remember that caffeine content is not the only factor in how an energy drink affects an individual. The source of the caffeine and the accompanying ingredients can also play a role.
- Caffeine Source: Doubleshot's caffeine primarily comes from coffee, which some people perceive as a smoother, less jarring energy boost compared to the synthetic caffeine often used in Monster and other traditional energy drinks.
- Sugar Content: The sugar rush and crash associated with energy drinks can significantly impact the overall feeling of energy. Monster's original flavor has a much higher sugar content than the standard Doubleshot Energy, though both brands offer sugar-free alternatives.
- Individual Sensitivity: A person's metabolism and tolerance to caffeine can vary greatly, influencing how they react to different levels of the stimulant.
- Added Ingredients: Additives like taurine and guarana, while not definitively proven to boost energy significantly beyond caffeine, may contribute to the overall stimulating effect.
Caffeine Comparison Table
| Drink | Size | Caffeine (mg) | Notes |
|---|---|---|---|
| Monster Energy Original | 16 fl oz | 160 mg | Contains taurine, ginseng, guarana |
| Starbucks Doubleshot Energy | 15 fl oz | 135 mg | Standard formula |
| Starbucks Doubleshot Energy "Strong Coffee" | 15 fl oz | 225 mg | More potent version |
| Starbucks Tripleshot Energy | 11 fl oz | 165 mg | Higher concentration than standard Doubleshot |
Which Should You Choose?
Ultimately, the choice between Starbucks Doubleshot Energy and Monster depends on your specific needs and preferences. If you want the most caffeine in a single standard can, Monster Original has a slight edge over the typical Doubleshot. However, if you are seeking the highest possible caffeine content from a canned option, Starbucks' "Strong Coffee" varieties provide a more powerful dose. For those who prefer a coffee base, Doubleshot is the clear choice, while Monster appeals to fans of traditional energy drink flavors.
Regardless of your choice, it is vital to consume caffeine responsibly. The FDA recommends that healthy adults limit their daily caffeine intake to no more than 400mg. Knowing the specific caffeine content of your drink of choice is key to staying within healthy limits.

Conclusion
In conclusion, a standard 16 oz can of Monster Energy contains more caffeine than a standard 15 oz can of Starbucks Doubleshot Energy. However, the comparison is not always so straightforward, as Starbucks offers more potent canned options, including its 15 oz "Strong Coffee" Doubleshot with 225 mg and the 11 oz Tripleshot with 165 mg, that pack a bigger caffeinated punch than Original Monster. When making your choice, consider not only the caffeine quantity but also the other ingredients and your personal taste preferences.
