Lattes, cappuccinos, macchiatos, and flat whites all contain espresso and range in caffeine amounts by number of espresso shots. Depending on the drink you choose, a short or tall version could contain either one or two shots of piping-hot espresso (each shot has 75 mg of caffeine). Grande and tall versions of these varieties could contain two shots — bringing the cup to a 150 mg value, which is still under that 200 mg limit (woo-hoo!) — but some could have three shots, bringing it 25 mg over the daily limit. Just be sure to double check with your barista, and ask to tweak the number of shots if necessary!
