Understanding the Caffeine in Dark Chocolate
Caffeine is a natural compound found in cocoa beans, which are the primary ingredient in all chocolate. The amount of caffeine in a chocolate bar depends heavily on its cocoa content; the more cocoa solids, the more caffeine. Hershey's Special Dark is considered a mildly sweet dark chocolate, which contains a moderate amount of cocoa solids, placing its caffeine level between milk chocolate and very high-cacao dark chocolate varieties.
The 20mg of caffeine found in a 1.55-ounce bar of Hershey's Special Dark is significantly less than the 95mg found in an average cup of brewed coffee, but it is enough to have a mild stimulating effect, especially for those sensitive to caffeine. It's also important to note that chocolate contains another, milder stimulant called theobromine. Theobromine is present in much higher concentrations than caffeine and contributes to the overall energy-boosting and mood-enhancing effects of dark chocolate.
Factors Influencing Caffeine Levels in Chocolate
Several factors can cause variation in the caffeine content, even within the same type of chocolate:
- Cocoa Percentage: The most significant factor. As the percentage of cocoa solids increases, so does the caffeine content. For instance, an 85% cacao bar will have more caffeine than Hershey's Special Dark, which has about 45% cocoa solids.
- Cocoa Bean Origin: The origin of the cocoa beans can affect their natural caffeine levels. Beans from some regions, like Ecuador, naturally contain more caffeine than beans from West Africa.
- Processing Methods: While roasting doesn't significantly alter caffeine, alkalization (also known as 'Dutch processing') can reduce it slightly. Hershey's processes its Special Dark with alkali, which also lowers its beneficial flavanol content.
- Serving Size: The total caffeine consumed directly relates to the serving size. Eating more chocolate means a higher intake of caffeine and theobromine.
Caffeine Comparison: Hershey's Special Dark vs. Common Beverages and Chocolates
This table illustrates how the caffeine in a 1.55-ounce (approx. 44g) Hershey's Special Dark bar compares to other popular sources.
| Product | Serving Size | Approximate Caffeine Content |
|---|---|---|
| Hershey's Special Dark | 1.55 oz bar | 20 mg |
| Brewed Coffee | 8 oz | 95-200 mg |
| Coca-Cola | 12 oz can | 30-40 mg |
| Milk Chocolate (standard) | 1.55 oz bar | ~9 mg |
| 70-85% Dark Chocolate | 1.5 oz bar | 25-40 mg |
| White Chocolate | 1.5 oz bar | 0 mg |
The Role of Theobromine
While caffeine is a potent central nervous system stimulant, theobromine is a milder and longer-lasting one. Dark chocolate, especially high-cocoa varieties, contains a much larger amount of theobromine than caffeine. This combination of stimulants in chocolate provides a more gentle and prolonged energy lift compared to the rapid jolt from coffee, which can lead to a crash.
Making Informed Choices
If you are mindful of your caffeine intake, the amount in a Hershey's Special Dark bar is typically not a concern for most people. For comparison, it's roughly half the caffeine of a can of cola and less than a quarter of a cup of coffee. However, for those with high caffeine sensitivity, or if consumed in larger quantities, it's a factor worth considering. Always check the nutritional information for the specific chocolate product, as caffeine levels can vary by brand and cocoa content. For a caffeine-free chocolate option, white chocolate is the best choice as it contains no cocoa solids.
Conclusion
In summary, a standard 1.55-ounce Hershey's Special Dark bar contains approximately 20mg of caffeine. This amount is moderate compared to other caffeinated products, sitting between a regular milk chocolate bar and a cup of coffee. The caffeine content is influenced by the chocolate's cocoa percentage and processing, and it works alongside the higher concentration of theobromine to provide a balanced stimulating effect. By understanding these factors, you can enjoy this mildly sweet dark chocolate bar while remaining aware of your overall caffeine consumption.

Frequently Asked Questions
Is Hershey's Special Dark a significant source of caffeine?
No, it is not considered a significant source. A single bar contains about 20mg of caffeine, which is much less than a standard cup of coffee (95-200mg).
How does the caffeine in Hershey's Special Dark compare to a cup of coffee?
A standard cup of coffee has significantly more caffeine. You would need to eat several Hershey's Special Dark bars to match the caffeine content of just one average cup of coffee.
Why does dark chocolate have more caffeine than milk chocolate?
Dark chocolate contains a higher concentration of cocoa solids than milk chocolate. Since caffeine is found in cocoa solids, the higher cocoa percentage results in higher caffeine content.
Is it okay to eat Hershey's Special Dark before bed?
For most people, the 20mg of caffeine is unlikely to interfere with sleep. However, if you are very sensitive to caffeine, it's best to avoid it late in the day.
Does Hershey's publish the exact caffeine levels of its chocolate?
While Hershey's does not actively publicize the caffeine levels on its packaging, historical data and nutritional analyses confirm the caffeine content. Data from 2025 indicates a 1.55oz bar contains 20mg.
What is theobromine and how does it relate to caffeine in chocolate?
Theobromine is a milder stimulant found alongside caffeine in cocoa solids. Dark chocolate has much higher levels of theobromine than caffeine, and it provides a more sustained, gentler energy boost.
Is there caffeine in Hershey's Kisses or Milk Chocolate bars?
Yes, but very little. A 1.55oz Hershey's Milk Chocolate bar contains only about 9mg of caffeine. White chocolate contains no caffeine at all, as it has no cocoa solids.
