A typical chocolate-covered espresso bean contains about 12–14 mg of caffeine, though this varies based on the size of the bean and the chocolate coating. A single whole espresso bean holds roughly 6–8 mg of caffeine, while the chocolate covering (usually dark or milk chocolate) adds little to no caffeine unless it's specifically a dark chocolate with high cacao content. The amount of caffeine in a chocolate-covered espresso bean is significantly less than a cup of coffee (which contains 95–200 mg) or a regular espresso shot (63–70 mg), since an espresso bean is only a small fraction of the liquid espresso. However, chocolate-covered espresso beans are concentrated treats, and consuming a handful can add meaningful caffeine intake. People often enjoy them for the combination of the coffee flavor, mild caffeine boost, and chocolate taste. For context, eating 10 chocolate-covered espresso beans would provide roughly 120–140 mg of caffeine, equivalent to a small cup of coffee. Since individual beans vary in size and roast level (which affects caffeine concentration), the exact amount differs between products and brands.
