Top 20 Most Caffeinated Coffees
Over the past few years, we’ve experienced something like a caffeine arms race. Coffee blenders and roasters have been creating brews with astonishing levels of caffeine.
Now it’s time to round up all kinds of coffees – from restaurants like Starbucks to ready-to-drink formulations to more traditional blends.
The results are somewhat frightening, given that most health authorities recommend no more than 400mg of caffeine per day.
Some of these coffees have the potential to make anyone without a massive caffeine tolerance feel quite unwell…

Among the outlet coffees, Starbucks brewed coffee is consistently high in caffeine, followed by Dunkin’ Donuts. Cold brews are also a favorite among caffeine lovers.
What makes these coffees so caffeinated?
The coffees at the top of the list use roasted robusta coffee beans, which are higher in caffeine than the standard arabica coffee bean.
Robusta can have 2-3 times the caffeine typically found in arabica. Plus, roasters are purposely seeking out robusta beans that have the highest levels of caffeine possible.
Most people prefer the taste of Arabica coffee beans because of their flavor profile, which meant in the past, Robusta beans were primarily used in only instant coffee.
