The caffeine content in coffee VARIOUS SIGNIFICANTLY depending on: the type of bean (robusta has twice the caffeine of arabica), the roast (less roasted = more caffeine), the grind (finer grind = more caffeine), purity (torrefacto coffee, despite its dark color and strong flavor, has less caffeine than 100% natural coffee without added sugar and other ingredients).
The caffeine in a cup of coffee with milk can vary greatly depending on the amount served (small 125 ml cup or standard 250 ml cup), the amount and type of coffee used, and the coffee-to-milk ratio (coffee/milk 1:1, 1:2, or 1:3).
The food/beverage with the highest caffeine concentration per ml/g is the espresso coffee (with up to 250 mg per 100 ml).
The caffeine content of energy drinks is typically 32 mg of caffeine per 100 ml of the drink, but you can verify the exact amount on the product labels.
