A cup of instant coffee contains about 40 - 120 mg caffeine. A cup is usually understood to contain 150 ml (5 oz in the United States), but the range of measurements is so wide that, for most individuals, it is inaccurate to use these figures as a basis for calculating the exact amount of caffeine consumed in a day.
Topping the list with the most caffeine per cup are Starbucks' Bold Pick of the Day, Blonde Roast, Clover Brewed Coffee and Pike's Place Roast. Although Starbucks notes that the caffeine levels of these drinks may vary, they are listed on the Starbucks website as: 1  Short - 180 mg. 2  Tall - 260 mg. 3  Grande - 330 mg.
