Question: Which has more caffeine? A dark roast or a medium or a light roast?
The short answer is they all have about the same amount of caffeine. Caffeine is very heat stable. But there can be a loss of mass in the roasting process that would mean that equal weights of bean might have different small levels of caffeine.

So, how does this change a pot of coffee?

If you measure your coffee by scoops, light roasted coffee will have more caffeine. Since the beans are denser than a darker roast. However if you weigh out your scoops, darker roasts will have more caffeine, because there is less mass. What should also be noted is that Arabica beans vary in levels of caffeine depending on the plant species.

And, as we know from our caffeine basics the amount of caffeine in a cup of coffee is so minimal, we might not even notice the difference.
