                                Typically made with robusta beans that contain nearly double the caffeine of standard arabica, Vietnamese coffee is notoriously strong. A 12 oz serving of Vietnamese coffee is a non-traditional but popular size, and its caffeine content can range significantly higher than an average cup, often exceeding 350 mg.
