                                According to International Delight, a 15-oz can of their ready-to-drink Reese's iced coffee contains approximately 90 mg of caffeine. This confirms that Reese's coffee, specifically the popular iced coffee product, is not caffeine-free, offering a significant pick-me-up for fans of the iconic chocolate-peanut butter flavor.
