Maybe you have been surprised to drink a coffee drink and find that you still feel tired afterward; or, maybe you have drank what you thought was just a small amount of coffee and subsequently felt jittery; if either of these are the case for you, you might benefit from knowing the caffeine content of the drinks you are drinking.For many Americans, Starbucks is the coffee destination of choice. Of all the specialty drinks offerred at Starbucks, few are as popular as the Frappuccino. You will espcially see people drinking this drink – and might even be especially tempted by this drink yourself – during the hot summer months, but did you know that the Frappuccino has no caffeine in it? In fact, the Frappuccino contains no real coffee – it is powder-based and coffee-flavored! If you are wanting something to wake you up during the summer instead of just a cold drink, think twice before purchasing a Frappuccino. Espresso is another area where one of the big caffeine myths comes from. You might even find a barista making a comment along the lines of, “You must really need to stay awake” if you ever order and espresso-based drink and ask for an extra shot to be added. But while espresso does, in fact, contain more caffeine per ounce than coffee, it is rare for an espresso-based drink to contain more than two or three ounces of actual espresso. For instance, if you go to Starbucks and order a venti latte – the largest size available – you will only be getting three ounces of espresso. As a shot of espresso typically contains between 35 and 50 milligrams of caffeine, this amounts to between 105 and 150 milligrams of caffeine. On the other hand, a single cup of coffee will typically give you between 115 and 150 milligrams of caffeine. This means that a venti coffee gives you over 300 milligrams of caffeine! In other words, a venti coffee actually contains more than double what you will find in a venti espresso drink! As surprising as it sounds, those who are sensitive to caffeine would be better off order espresso-based drinks than plain coffees. You just need to know how many shots are in a drink, and you can be aware of how much caffeine you are consuming. And if you have been tired and wondering why these coffee drinks do nothing, maybe you are getting a lot less caffeine than you realized! @@ADSENSE@@.
