Do Light Roasts Have Less Caffeine Than Dark Roasts?

Many people are fooled by the common coffee myth that dark roasts have more caffeine than light roasts because they have a fuller and more robust flavor. However, quite the opposite is true!

A dark roast is roasted for a longer period of time, which means that it ends up burning off some of its weight in caffeine during the lengthy roasting process. This means that pound for pound, a light roast will have more caffeine than a dark roast. Furthermore, keep in mind that Robusta beans actually have twice the caffeine as Arabica beans, though they are not the preferred coffee bean type because they are seen as cheaper fillers with a lower quality taste.

When you're considering a cup of Joe, a regular cup of coffee will have more caffeine than a shot of espresso because of the extraction time. An espresso is extracted for ideally around 25 seconds, and a cup of coffee can take up to four minutes to extract. This means that the fresh coffee grounds are in contact with the hot water for longer, leaving more caffeine in the final cup of Joe.

For a quick fix with the most caffeine, try a light roast to wake you up!
