Everybody's got their favorite brand of coffee. For most of us, it's the brand that we feel wakes us up the best. You're probably thinking your brand has the most caffeine out there. You're... probably wrong.
When it comes to chain coffee companies (the places you're most likely getting your coffee from), Starbucks came in at #2 for the most caffeine with 20.6 milligrams per ounce. It was only beat out by Coffee Bean and Tea Leaf by a small margin. Compare that amount to McDonald's coffee which only has 9.1 milligrams of caffeine per ounce... yikes!
Maybe that's why Starbucks costs so much? Ehh, probably not, but it makes me feel better anyway.
Now if you want a real jolt, check out some of the more unconventional coffees out there. Devil Mountain Coffee Co. Black Label Brewed Coffee (that's a mouthful) has 129.6 milligrams of caffeine per fluid ounce! WHOA!
