A Lighter Roast Will Have More Caffeine
What roast of coffee has the highest caffeine content? It depends on how you’re measuring it. The roasting process causes a bean to lose its mass and density. So if you’re using a scoop, a lighter roast will have more caffeine. But…if you weigh your coffee instead, a darker roast will provide more of a caffeine boost. Overall though, the difference is caffeine content is negligible.
