You already know that decaf coffee has less caffeine than regular strength coffee, but did you know that every place you order a cup of joe will have different caffeine levels? In fact, you might like the taste of McDonald’s coffee more than Starbucks, but if you really need a good caffeine buzz to wake up, you’d better skip the Golden Arches, or at least order two cups because McDonald’s coffee only has 9.1 mg of caffeine compared to Starbuck’s 20.6.
Of course, if you really need a mega-dose of caffeine, try Death Wish Coffee, which is known for being pretty much the strongest stuff on the market. How strong? Well, one cup has 54.2 mg of caffeine, two and a half times more than that of Starbucks, which is the next most potent brew in this infographic.
