                                According to the official Dunkin' Spiked website, Dunkin' Spiked Iced Coffees contain about 30 mg of caffeine per 12-ounce serving. This is significantly less than the caffeine found in a standard, non-alcoholic Dunkin' iced coffee, which contains around 100 mg per serving. The presence of real coffee in the malt-based alcoholic beverages means that while they are designed for adult consumption, they still retain a small stimulant effect.
