Yes I understand the title is a bit dramatic, but my mind has been blown while ordering my coffee this morning! The barista and I know each other well (we see each other almost every day) and he said "the usual?" and I said "yes! I need a lot of caffeine today."
He then proceeded to tell me to get the blonde roast instead this morning.... because LIGHT ROASTS HAVE MORE CAFFEINE.
How have I not known this before? Why has no one ever told me this? It didn't make any sense to me as I always though lighter coffees had less caffeine and weren't as strong.
Dark roast coffees actually have less caffeine than lighter roasts. A strong, rich flavor might seem to indicate an extra dose of caffeine, but the truth is that light roasts actually pack more of a jolt than dark roasts.
From the Livestrong website:
When you peruse coffee labels, you will likely see a roast type: light, medium or dark. This is an indicator of flavor strength, with the dark roasts having the boldest tastes. The darker the beans, the longer they have been roasted. While a stronger dark roast might seemingly have a higher caffeine content, this is not true based on the roasting process. The longer coffee beans are roasted, the more caffeine is burned off. Light roasts aren’t as strong, but they pack the most caffeine.
I honestly had no idea. I don't know if I'm the last person to find this out (my office didn't know this as well), but I thought this gold nugget of information should be shared. I'll definitely be ordering light roast coffees from now on!
P.S. would love for you to comment if you also didn't know this!!
