Dark roasts are less dense, so each bean has slightly less caffeine. Light roast beans are more dense than dark roast beans, so each individual bean has slightly more caffeine. However, this caffeine myth does have an understandable origin. Measuring by weight (mass) will give you about the same caffeine every time, regardless of roast level. In reality, 50g of dark roast coffee and 50g of light roast coffee have roughly the same amount of caffeine. For the most part, this was just a bunch of misinformation and guessing. I always grew up hearing that dark roast coffee is “strong” and has the most caffeine.
