Whether you're a daily coffee drinker or just curious about the world’s most popular beverage, there are some surprising truths behind your cup. Let’s break down 10 essential coffee facts that reveal what makes coffee not just a drink, but a global phenomenon.

Quick answer: A single shot of espresso contains just 2 calories, while the caffeine extraction varies drastically—65% from espresso versus 98% from a French press.

What’s Really in Your Espresso?

An average single shot of espresso contains only 2 calories. That’s right—virtually calorie-free. This makes espresso one of the lowest-calorie ways to consume caffeine, especially when compared to sugary coffee drinks. The minimal calorie count is due to the small serving size and lack of added milk or sugar, keeping it a favorite choice for those watching their intake.

Caffeine Extraction: Espresso vs. French Press

The way you brew coffee dramatically affects caffeine extraction. When making espresso, only about 65% of the caffeine is extracted from the coffee beans. In contrast, a French press (or cafetière) extracts up to 98% of the caffeine. This doesn’t necessarily mean more caffeine per cup, as brew volume and concentration also play major roles, but it does highlight how brew method influences what ends up in your drink.

Spoken similarly in nearly every language around the globe—from English and Spanish to Japanese and Arabic—the word has remained surprisingly consistent.

The first espresso machine that used pressure to brew coffee was invented by a Frenchman in 1901. This groundbreaking technology paved the way for the modern espresso machines we use today. Later, in 1973, Italian company Illy introduced the first coffee capsule system, revolutionizing how coffee is brewed at home and in offices.
