Vietnamese coffee typically contains robusta coffee beans, which are higher in caffeine content than arabica beans commonly used in other types of coffee. The amount of caffeine in a cup of Vietnamese coffee can vary depending on the brewing method, the type of beans used, and the serving size.
On average, a cup of Vietnamese coffee contains about 80-200 mg of caffeine per 8-ounce serving. However, some variations, such as the popular Vietnamese iced coffee or cà phê đá, may contain more caffeine due to the concentrated nature of the brew and the addition of condensed milk.
