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.
So UF researchers set out to conduct a two-phase study designed to gauge just how much caffeine is likely to turn up in decaffeinated coffees. First they purchased 10 16-ounce decaffeinated drip-brewed coffee beverages from nine national chains or local coffee houses and tested them for caffeine content.
