Unveiling the Hidden Caffeine in Your Refresher
A common misconception is that because refreshers are fruit-flavored and brightly colored, they must be caffeine-free. This belief often leads parents to purchase them for their children or individuals with caffeine sensitivities to consume them unaware. The reality is quite the opposite. Most major chain refreshers, including those from Starbucks and Dunkin', contain a noticeable amount of caffeine. The source of this caffeine is an essential detail that differentiates it from a typical cup of joe, and it's the key to understanding the full picture of these popular beverages.
The Source: Green Coffee and Green Tea
For most Starbucks Refreshers, the caffeine comes from natural green coffee extract. Green coffee beans are coffee beans that haven't been roasted. This process skips the heat that would typically produce the dark, roasted coffee flavor, but it retains the natural caffeine. By using this extract, Starbucks can infuse their refreshers with a jolt of energy without altering the drink's fruity taste. Dunkin' Refreshers, on the other hand, derive their caffeine from green tea extract. This means while both types of beverages are caffeinated, the specific botanical source differs.
Caffeine Levels in Starbucks Refreshers
For Starbucks customers, the amount of caffeine in a refresher is consistent across all flavors for a given size. This is due to the standardized refresher base concentrate.
- Tall (12 oz): 35-45 mg of caffeine.
- Grande (16 oz): 45-55 mg of caffeine.
- Venti (24 oz): 70-85 mg of caffeine.
- Trenta (30 oz): 90-110 mg of caffeine.
Caffeine Levels in Dunkin' Refreshers
Dunkin' Refreshers use a green tea base for their energy boost. The caffeine content is generally higher than Starbucks refreshers, but still less than a standard cup of coffee.
- Small (16 oz): 66 mg of caffeine.
- Large (32 oz): 132 mg of caffeine.
A Deeper Look at Refresher Ingredients
Beyond the caffeine source, the ingredients that make up a refresher are worth noting. For example, a Starbucks Strawberry Açaí Refresher includes:
- Water and white grape juice concentrate for the base.
- Citric acid and natural flavors.
- Green coffee flavor for the caffeine.
- Fruit and vegetable juice for color.
- Freeze-dried strawberries for texture and added flavor.
It's important to remember that these beverages often contain a significant amount of sugar, which can also contribute to an energy spike followed by a potential crash. For example, a Grande Strawberry Acai Refresher contains 21 grams of sugar.
Comparison Table: Refreshers vs. Other Drinks

| Dunkin' Refresher | Small (16 oz) | 66 | Green Tea Extract | Slightly higher caffeine than a Starbucks Refresher. |
| Brewed Coffee (Starbucks) | Grande (16 oz) | 165 | Coffee Beans | A much higher dose of caffeine. |
| Matcha Latte (Starbucks) | Grande (16 oz) | 65 | Green Tea Powder | Similar caffeine level to a Dunkin' Refresher. |
| Can of Soda (Coca-Cola) | 12 oz | ~34 | Cola Nut, etc. | Varies by brand, but generally low. |
How Your Body Reacts to Refresher Caffeine
The caffeine in a refresher will still have an effect on your body, but it's typically milder than the effects of a strong coffee. The amount is comparable to a can of soda, which can still cause jitters or anxiety for sensitive individuals. For those monitoring their caffeine intake for health reasons, such as during pregnancy or due to a medical condition, even this moderate amount should be considered. A healthy adult's recommended daily limit is around 400 mg, but anyone sensitive to caffeine will feel the effects much sooner.

Conclusion: Refreshers Are Caffeinated, But Differently
In summary, the answer to the question "Do refreshers contain caffeine?" is a definitive yes. The caffeine is derived from less-common sources like green coffee or green tea extract, and the amount is generally moderate, especially when compared to standard brewed coffee. Consumers, especially parents and those with sensitivities, should be aware of this fact when choosing a beverage. While they provide a burst of energy, it's essential to recognize that it's not the same as a decaffeinated, simple fruit juice.
