Caffeine content also depends on how "bold" the coffee is. If we take it across the whole spectrum, coffee contains between 75 and 150 mg. of caffeine per 8 oz. cup, depending on the roasting strength and other factors. It is difficult to measure the nutritional content of coffee, because it varies depending on many things. Generally, the darker the coffee is roasted, the less caffeine it contains.
Almost all decaffeinated coffees still contain some caffeine. The international standard by which decaffeinated coffee is characterized is by having at least 97% of the caffeine removed. Decaf coffee should fall somewhere in the range of 2 to 4 mg. per 8 oz cup.
