On warm afternoons, there will be a line of people waiting to order frappes at almost every McDonald’s or Starbucks. Most of them are thinking of it as a treat—something sweet and cold that isn’t too serious. That’s where the confusion starts. Because a lot of those people really don’t know if what they’re holding has caffeine in it. Depending on what they asked for, the answer may come as a surprise.
In short, yes, most frappes do have caffeine in them. But the why and how much changes enough that it’s important to pay attention. There are about 75 milligrams of caffeine in a small frappe at McDonald’s. The weight of a medium goes up to about 85 milligrams. A large can have up to 130 milligrams of caffeine, which is about the same as a regular cup of drip coffee or a little more. The mocha versions are usually a bit more expensive, in part because chocolate has a small amount of caffeine in it. While it’s not huge, it’s also not small, and most people expect something with whipped cream on top to be bigger than this.
In the same way, Starbucks does business. Depending on the size, their coffee-based Frappuccinos like the Caramel, Java Chip, Mocha, and regular Coffee all have between 65 and 95 milligrams of caffeine. It’s interesting that Starbucks makes them this way: most of them don’t use freshly brewed coffee like a normal latte does. Baristas use something they call “Frappuccino Roast,” which is basically concentrated instant coffee powder that is mixed with water and then added to the drink’s base syrup. It’s stronger than it sounds, and it gives the drink a coffee flavor without having to do a full espresso pull for every order on a busy Friday afternoon.
It seems like frappes are mentally put in the same category as milkshakes instead of coffee drinks because they look like blended desserts. That’s a mistake that makes sense. You don’t think about how much caffeine something has when it comes in a box covered in caramel drizzle and smelling like a vanilla candle. That being said, the coffee is real, even if you can’t tell from the taste. Yes, that’s part of the point. The sweetness and ice hide the bitterness, which makes it easier to drink a lot of caffeine without noticing.
This is more complicated because not all frappes have caffeine in them. At Starbucks, the Vanilla Bean, Strawberries and Crème, and classic Strawberry cream-based drinks don’t have any coffee in them at all. Since they’re made with a cream base instead of a coffee base, they don’t have any caffeine in them unless you add a shot of espresso. If you ask, the barista can change any Frappuccino with coffee to one with cream. This is a standard choice, but it’s not advertized very much. It’s also possible to ask for decaf espresso in drinks that let you switch out the shot, but most places don’t have a direct decaf version of the Frappuccino Roast.
It is important to note that “frappe” does not always mean “coffee.” In some parts of Europe and the Mediterranean, like Greece, a frappé is just a cold coffee drink with foam on top. This is usually instant coffee mixed with water and ice. “Frappé” in French cooking can mean chilled or iced desserts that don’t have any coffee in them. The American fast food version of the word took the “cold and blended” part of that idea and mostly filled it with coffee flavoring. Since then, fruit, chocolate, and vanilla varieties have been added that don’t have any coffee at all.
People who are watching how much caffeine they drink, like pregnant women, people who have anxiety or sleep problems, and people who are just sensitive to caffeine, should look more closely at the frappe category than it usually gets. If you get a large McDonald’s frappe in the afternoon, it has enough caffeine to make you go over half of the daily limit for adults. It’s not scary, but it’s good to know. And that plastic cup with the green straw makes it impossible to tell the difference between a coffee drink and a dessert drink.
