10 Essential Facts About Coffee Everyone Should Know

Ever found yourself wondering how many calories are really in that shot of espresso—or why your French press cup feels so much stronger than your morning shot? You're not alone. Whether you're deep into espresso or just love a good cup, these 10 little-known coffee facts reveal surprising truths behind your daily brew.

Here’s the big picture: A single shot of espresso contains just 2 calories, while the caffeine extraction differs drastically between methods—espresso gives you 65% of the bean’s caffeine, but a French press extracts up to 98%. These aren’t opinions—they’re verified numbers that change how we understand our coffee.

Coffee Calories & Caffeine Extraction

An espresso shot contains only 2 calories. That’s right—just two. It’s one of the lowest-calorie beverage options around, especially when compared to sugary drinks or even many milk-based coffee options.

When it comes to caffeine extraction, not all brewing methods are equal. Espresso extracts about 65% of the available caffeine from the coffee beans, while a French press (or cafetière) extracts up to 98%. That means your French press cup likely has more caffeine than you think—more than an espresso, even if the volume is higher.

Global Coffee Culture & Language

The word “coffee” is pronounced remarkably similarly across almost every language. Whether you say “coffee” in English, “café” in French, or “kaffee” in German, the root sound is nearly identical worldwide—a rare linguistic consistency.

Globally, coffee is the second most consumed beverage after water, and tea comes in third. That makes coffee not just a drink, but a daily ritual for billions around the planet.

Coffee Innovation & Trade History

The first espresso machine that used pressure to brew coffee was invented by a Frenchman in 1901. This pivotal invention laid the groundwork for the modern espresso machines we rely on today.

In 1973, Italian coffee company Illy introduced the first coffee capsule system, revolutionizing how coffee could be brewed at home and paving the way for today’s single-serve formats.

Italy imports 52% of its coffee through the port of Trieste, making it the country’s largest coffee import hub. Meanwhile, 80% of coffee consumed in Italy is espresso, with just 20% being milk-based drinks like lattes or cappuccinos.

Coffee Varieties & Bean Science

There are around 200 types of raw, green coffee beans available globally. But once roasted, the flavor profiles multiply, and roasters can distinguish over 2,000 different roasted coffee varieties based on origin, roast level, and processing.

What you taste in your cup isn’t just about the bean type—it’s also about how it was roasted, where it came from, and how it was brewed. That’s why a Yirgacheffe and a Guji can taste wildly different even though they’re both Ethiopian.
