I am an unabashed fan of coffee and I split my love evenly between regular ol' joe and espresso drinks. But how do they stack up in terms of caffeine amounts? Or more explicitly, where am I going to get more bang for my buck?
Ounce for ounce, sip for sip, espresso contains more caffeine. Using the ubiquitous Starbucks as our model: one fluid ounce of espresso contains 75 milligrams of caffeine, where a fluid ounce of coffee only contains about 20 mg.
The confusion comes when you begin to compare lattes with coffee. A 16-ounce grande coffee provides 330 mg of
rocket fuel caffeine, where a grande latte, containing only two shots (each shot is a fluid ounce) of espresso, provides 150 mg of caffeine. Even though these coffee drinks come in the same sized cup, the caffeine amounts are substantially different. If you order a cup of coffee, instead of a latte, to save time or money, you might end up a little speedier than usual.
