You’d think cold brew would be weaker since it’s cold, right? Wrong. Because cold brew uses a higher coffee-to-water ratio—sometimes double the grounds. A large cold brew can contain 200-300mg of caffeine. That’s the legal limit for a “don’t talk to me before noon” zone. Iced coffee? Usually 150mg or less, depending on how strong your barista is feeling about their ex.
Fun fact: if you drink cold brew too fast, you might start writing poetry about your toaster. Pace yourself.
The Dilution Danger (Ice is the Enemy)
Iced coffee’s tragic flaw: the ice melts and dilutes the brew. One second you’re drinking a bold, dark roast; five minutes later, you’re sipping brown water that tastes vaguely of coffee’s ghost. To combat this, some cafes brew extra-strong hot coffee, or use coffee ice cubes. That’s thinking like a genius who also fears God.

Cold brew barely flinches at ice. Since it was already steeped in cold water, it has a stable concentration. It’s like a duck: water rolls right off. You can let it sit for an hour and it still tastes like a handshake from a professional. Except now it’s lukewarm, which is gross—but that’s your fault for sipping slowly.
