Mythbusters: Lighter Roasts Have More Caffeine
There are so many factors that affect caffeine content but the degree of roast is not one of them. In fact, there are arguments to suggest that a lighter roast would yield less caffeine. So here are a few facts - and I mean real facts - and some tips on how you can optimize the caffeine content of your brews at home.
If you read the article about our Robusta & Arabica blend, you’ll already know that Robusta has significantly more caffeine than arabica. My first point about roast styles is that you’ll generally find that the lighter roasts are from the speciality - or Third Wave - coffee roasteries, who tend to only use Arabica. Therefore, these lighter roasts will have a lower caffeine count than darker Robusta roasts.
Caffeine is an incredibly stable chemical, whose concentration in a single coffee bean will basically stay the same after roasting as it was beforehand. If you take into account other elements that decrease during roasting, including a drastic change in density, you could even argue that a darker roasted bean with lower density would yield more caffeine when brewed. This depends, however, on one vital step in brewing.
How Do You Measure Your Coffee???
Do you use a coffee scoop for your whole beans and/or ground coffee? Or do you weigh it out for each cup? Weighing out your coffee, whether it’s whole bean or ground, will help you maximize the amount of caffeine you’re getting.
