                                According to the National Coffee Association, the average 12-ounce cup of coffee contains between 113 to 247 mg of caffeine, but some specialty brands pack in far more. Determining which coffee is the most potent involves evaluating factors beyond the average cup, including bean type, brewing method, and brand-specific blends.
