I finally looked up how much caffeine is actually in my dark roast vs. a light roast and it messed with my head.
Pulled up a chart from some coffee science site after my buddy claimed light roast has more caffeine. Turns out he's right if you measure by scoop but wrong if you measure by weight. So basically all my assumptions about which roast keeps me awake are built on nothing. Has anyone else fallen down this rabbit hole and come out more confused?

A buddy of mine was dead set that light roast has more caffeine (which sent me down the same confusing path). Using a kitchen scale for my morning coffee was the only thing that made it click for me. Scoop for scoop, light roast is denser so you get more beans, but by weight it's basically the same. Now I just dose by grams instead of scoops and it's way less stressful.
