Heard a barista say 'dark roast has the most caffeine' and I snapped
I was standing at this little shop in Austin last Saturday, and the barista told a customer that dark roast beans have way more caffeine than light roast. I just stood there like, no, it's actually the opposite, light roast is denser so you get slightly more caffeine per scoop. Has anyone else had to bite their tongue when someone gets basic coffee facts totally wrong?
