Coffee is more than just a morning pick-me-up—it’s a drink steeped in history, culture, and fascinating quirks. While most people are familiar with its energizing effects, coffee has a world of surprises that might make you appreciate your cup even more.
Here are 10 surprising facts about coffee that go beyond the basics, shedding light on its origins, science, and global impact.
1. Coffee Was Discovered by Goats
Legend has it that coffee was discovered in Ethiopia in the 9th century by a goat herder named Kaldi. He noticed his goats becoming unusually energetic after eating red cherries from a particular shrub. Curious, Kaldi tried the cherries himself and experienced a similar burst of energy. This discovery led to the early use of coffee as a stimulant, eventually spreading to other cultures.
2. Coffee is the Second-Most Traded Commodity
After crude oil, coffee is the most traded commodity in the world. The global coffee industry is worth over $100 billion annually and supports the livelihoods of millions of farmers, traders, and baristas. Brazil, Vietnam, and Colombia are among the top coffee-producing countries.
Key Numbers
- Approximately 2.25 billion cups of coffee are consumed worldwide every day.
- Coffee contributes significantly to the economies of over 50 developing countries.
3. Decaf Coffee Isn’t Completely Caffeine-Free
Despite its name, decaf coffee still contains trace amounts of caffeine. A typical cup of decaf has about 2–5 mg of caffeine, compared to the 95–200 mg found in regular coffee. The decaffeination process removes around 97% of the caffeine but doesn’t eliminate it entirely.
4. Coffee Can Be Enjoyed in Space
Astronauts aboard the International Space Station can enjoy coffee, thanks to specially designed zero-gravity coffee cups and an espresso machine called ISSpresso. This innovation ensures that astronauts can enjoy their favorite brew while orbiting Earth.
5. Coffee Was Once Banned
Coffee has faced bans and controversies throughout history. In the 16th century, leaders in Mecca prohibited coffee, fearing it encouraged rebellion. Similarly, in 18th-century Sweden, King Gustav III conducted an experiment to prove coffee’s dangers, but the results were inconclusive.
Why the Controversy?
- Coffee houses were often associated with political discussions, making them a target for rulers wary of dissent.
- The stimulating effects of coffee were sometimes viewed with suspicion.
6. Espresso Means “Pressed Out”
The word espresso comes from the Italian term meaning “pressed out.” It refers to the brewing process, where hot water is forced through finely-ground coffee under high pressure. This method creates a concentrated and flavorful coffee shot with a layer of crema on top.
Fun Fact:
It’s a common misconception that espresso has more caffeine than regular coffee. While it’s more concentrated, a standard serving of drip coffee often contains more caffeine due to its larger volume.
7. Coffee Can Extend Your Life
Studies suggest that drinking coffee may offer health benefits, including a reduced risk of certain diseases. Regular coffee consumption has been linked to:
- Lower rates of type 2 diabetes.
- Reduced risk of Parkinson’s disease and Alzheimer’s disease.
- Protection against liver conditions, such as cirrhosis and liver cancer.
Why?
Coffee is rich in antioxidants, which help combat inflammation and oxidative stress in the body.
8. Kopi Luwak: The World’s Most Expensive Coffee
Kopi Luwak, also known as civet coffee, is made from beans that have been eaten and excreted by civets, small mammals native to Southeast Asia. The digestion process alters the beans, resulting in a unique flavor profile.
Price Tag:
Kopi Luwak can cost up to $600 per pound, making it one of the most expensive coffees in the world. However, its production has faced ethical concerns regarding the treatment of civets.
9. The First Webcam Was Invented to Monitor Coffee
The world’s first webcam was created in 1991 by researchers at the University of Cambridge. Its sole purpose? To monitor the coffee pot in their office, ensuring that they didn’t waste trips to the break room only to find the pot empty.
The Camera:
The system, called the Trojan Room Coffee Pot Webcam, became an early example of live-streaming technology and remained in operation until 2001.
10. Coffee Can Be Used as a Natural Pest Repellent
Used coffee grounds are effective at repelling pests such as ants, mosquitoes, and slugs. The caffeine and strong aroma deter insects and can even enrich soil when added to compost.
How to Use Coffee Grounds:
- Sprinkle them around plants as a natural fertilizer and pest deterrent.
- Place them in bowls to absorb odors in your home.
