WHICH ROAST HAS MORE CAFFEINE?
Neither. Dark roast and light roast coffee basically contain equal amounts of caffeine.
It’s not a question of light or dark roast. Nope. The amount of caffeine is decided by the amount of coffee used when brewing. Want more caffeine kick? Then just add more coffee!
Some coffee drinkers think dark roasts are stronger and have more caffeine kick than light roasts. The truth, however, is that caffeine content remains pretty much the same during each stage of the roasting process. The difference between roasts is taste, not the amount of caffeine. The simple rule of thumb is: It ain’t the shade of bean; just add more coffee to get more caffeine.
Put that in the press and sip it!
An exception to every rule? Yup. Here it is: if measured by weight, caffeine content is virtually equal in light roast and dark roast coffee. But, if measured by scoop, light roast coffee will have oh-so-slightly more caffeine, since the beans are denser than a darker roast. Because they’ve been roasted longer, dark roasts have less mass.
So, now that the light vs. dark caffeine myth is cleared up, all that’s left to do is figure out which coffee tastes best! That’s right, although each roast contains the same amount of caffeine, there are many other differences between Light Roast and Dark Roast coffee to be savored.
