10 Surprising Facts About Coffee You Probably Didn’t Know

Ever wondered how many calories are really in your espresso? Or why almost every language says ‘coffee’ almost the same way? If you’ve ever sipped a shot and thought there had to be more to your cup than meets the eye, you’re right. There’s a surprising amount of little-known science, history, and culture packed into every cup — and some of it might just change how you think about your daily brew.

Here’s the quick answer: a single shot of espresso contains just 2 calories, while French press coffee retains nearly all of its caffeine — up to 98%. Coffee is the world’s second most consumed beverage after water, and the way we talk about it hasn’t changed much across languages. These are just a few of the lesser-known truths about your favorite drink.

How Many Calories Are Really in Espresso?

A single shot of espresso contains only 2 calories. That’s right — just two. For anyone watching their intake, especially those on calorie-restricted diets, that makes espresso one of the lowest-calorie beverage options around. It’s also why many people looking to enjoy a warm, flavorful drink without the calories often turn to espresso or espresso-based drinks without added sugar or milk.

The Universal Word: Why Does ‘Coffee’ Sound Similar Everywhere?

The word ‘coffee’ is pronounced similarly in nearly every language around the world, from English to Japanese. Even in languages where it’s adapted — like ‘kafe’ — the root sound remains strikingly consistent. This linguistic uniformity points to coffee’s long journey along global trade routes and its deep cultural integration across continents.

Coffee vs. Tea: What’s the World’s Most Popular Drink After Water?

After water, coffee is the second most consumed beverage in the world, with tea coming in third. This ranking highlights coffee’s massive global footprint and its role as a daily staple for millions. Whether it’s a quick espresso in Naples or a slow pour-over in Portland, coffee remains a universal constant in the daily lives of people across the globe.

What Happens to Your Brain When You Drink Coffee?

Drinking coffee causes a noticeable reaction in the brain — some describe it as a slight ‘vibration’ or mental jolt. This neurological response is one reason why coffee is often recommended to help relieve headaches. The stimulating effect comes primarily from caffeine’s interaction with the brain’s neurotransmitters, which can improve alertness and focus almost immediately.

Espresso vs. French Press: Which Has More Caffeine?

When brewing espresso, about 65% of the caffeine is extracted from the coffee beans. In contrast, using a French press (or plunger pot) extracts up to 98% of the available caffeine. That makes French press coffee a go-to choice for those seeking a stronger caffeine kick — especially professionals needing a midday boost without drinking multiple shots of espresso.

How Many Types of Coffee Beans Exist?

There are approximately 200 types of raw, green (unroasted) coffee beans, but once roasted, the flavor profiles multiply, resulting in over 2,000 distinct roasted coffee varieties. This huge range of flavors and aromas is what makes specialty coffee so diverse and exciting for coffee enthusiasts to explore.

The History of the Espresso Machine

The first espresso machine that used pressure to brew coffee was invented by a Frenchman in 1901. That device laid the foundation for the modern espresso machines we use today. Though it’s been over a century, the core principle of using pressure to extract concentrated coffee remains at the heart of every espresso shot pulled around the world.

Italy’s Love Affair With Espresso

In Italy, 80% of all coffee consumed is espresso — the pure, unadulterated shot that’s meant to be sipped quickly. The remaining 20% includes espresso with milk, such as cappuccinos and lattes. Italians typically drink espresso straight, often standing at the bar, emphasizing the cultural importance of simplicity and tradition in coffee preparation.

The Coffee Pill Machine Invention

In 1973, Italian coffee company Illy invented the first coffee capsule machine. This early form of single-serve coffee technology paved the way for the modern pod systems we see today, transforming how coffee is brewed and consumed in homes and offices around the world.

Italy’s Coffee Import Hub

In Italy, 52% of all coffee imports arrive through the port of Trieste, making it the country’s largest coffee import gateway. This strategic location has helped establish Trieste as a central node in Europe’s coffee supply chain, influencing both the flow and quality of coffee available throughout the country.
