10 Coffee Facts You Need to Know

Coffee is part of everyday life for millions of people, but there’s much more inside your cup than caffeine and roasted beans. These coffee facts involve fruit, centuries of trade, unusual legends, pollinating bees and plants grown across some of the world’s most distinctive landscapes.

Unfortunately, some popular coffee facts repeated online aren’t quite as factual as they first appear.

So we’ve put together 10 coffee facts that separate what we know from the myths and legends surrounding one of the world’s favourite drinks.

1. Coffee beans aren’t really beans

Let’s begin with one of the most surprising coffee facts: coffee beans aren’t technically beans.

They’re seeds.

Coffee plants produce fruits commonly known as coffee cherries. Inside the fruit you’ll usually find two seeds facing one another.

Those seeds are removed from the fruit and processed before eventually becoming the green coffee that roasters buy.

Roasting transforms those relatively pale green seeds into the aromatic brown coffee beans we’re familiar with.

So when you open a bag of freshly roasted coffee, you’re actually looking at roasted seeds from the fruit of a coffee plant.

2. The story of Kaldi and his goats is probably a legend

One of the most famous coffee facts is actually better described as a legend.

The story tells of an Ethiopian goat herder called Kaldi who noticed his goats becoming unusually energetic after eating fruit from a coffee plant.

Kaldi supposedly took the fruit to a nearby religious figure, eventually helping lead to the discovery of coffee as a drink.

It’s a wonderful story, but there’s no reliable contemporary historical evidence establishing that Kaldi discovered coffee in the ninth century.

The tale appeared in written accounts much later.

What we can say with much greater confidence is that Coffea arabica has its biological origins in Ethiopia and neighbouring parts of East Africa, while Yemen became enormously important to the early cultivation and trade of coffee.

Our Arabica coffee beans guide explores that history in more detail.

3. Bees can help coffee plants

Here’s one of our favourite coffee facts from the natural world.

Coffee plants produce flowers before they produce fruit, and those flowers can attract bees and other insects.

Arabica coffee is capable of self-pollination, so it doesn’t depend entirely on bees to produce coffee.

However, that doesn’t mean pollinators are irrelevant.

Research published in Nature found that bee pollination could significantly increase fruit production in Arabica coffee.

The relationship between coffee farming and biodiversity is therefore more interesting than simply saying that coffee plants need bees.

Suitable habitats around coffee farms can support pollinators while those pollinators may, in turn, benefit coffee production.

4. Arabica and Robusta aren’t the same coffee

One of the most useful coffee facts is that not all coffee comes from the same species.

Two of the most commercially important are Coffea arabica, known as Arabica, and Coffea canephora, commonly called Robusta.

Arabica dominates much of the specialty coffee market and contains enormous diversity in terms of varieties, origins and flavour profiles.

Robusta generally contains more caffeine and is frequently associated with greater bitterness and body. It’s commonly found in instant coffee and is also used in some espresso blends.

That doesn’t mean every Arabica is automatically excellent or every Robusta is poor quality.

Species is only one part of what determines the character and quality of your cup.

5. Coffee has a long connection with Yemen

Some coffee facts become confusing because the biological origin of the plant and the history of coffee drinking aren’t necessarily the same thing.

Among the most important coffee facts is that Arabica’s wild origins are associated with Ethiopia and neighbouring East Africa.

Yemen, however, played an enormously important role in coffee’s development as a cultivated crop and traded commodity.

Coffee cultivation became established there centuries ago, and Yemen helped connect coffee with markets beyond the region.

The port of Mocha — also written Mokha or al-Makha — became particularly important to the coffee trade.

Its name would eventually become permanently associated with coffee, although the modern chocolate-and-coffee drink we call a mocha is a different part of that story.

6. Early coffee houses became important social spaces

Historical coffee facts show that coffee houses have been part of coffee culture for centuries.

Early establishments appeared in the Middle East before coffee houses spread into Europe.

These weren’t simply places to buy a drink.

Coffee houses became social spaces where people could meet, exchange news, talk, listen to music and discuss the events of the day.

As coffee spread through Europe, coffee houses became established in cities including London.

The precise claim that one particular establishment was definitively the “world’s first coffee house” is difficult to substantiate, so it’s better to understand their emergence as part of the wider development of coffee culture.

Modern independent cafés may look completely different, but the social element of coffee has survived remarkably well.

7. Coffee consumption has been linked with liver health

Not all interesting coffee facts concern history.

Coffee has been extensively studied in relation to health.

A major umbrella review published in The BMJ examined evidence across numerous health outcomes and found that coffee consumption was associated with lower risks for several liver conditions.

That included associations involving chronic liver disease and cirrhosis.

But there’s an important distinction between association and causation.

Much of the evidence comes from observational research, meaning it can’t prove that drinking coffee directly prevents liver disease.

Coffee shouldn’t therefore be treated as a medicine or replacement for professional medical advice.

For a broader look at the evidence, read our guide to the benefits of coffee.

8. Dark roast doesn’t automatically mean more caffeine

This is one of those coffee facts that challenges a common assumption.

A dark, intense-tasting cup might seem as though it should contain much more caffeine than a lighter roast.

But darker flavour doesn’t automatically mean higher caffeine.

The amount of caffeine in your finished drink depends on several variables, including the coffee, how much you use and the brewing method.

Even the way coffee is measured can affect comparisons between roast levels because roasting changes the physical properties of the beans.

It’s therefore better not to judge caffeine content simply by how strong or bitter your coffee tastes.

If caffeine is what you’re thinking about, our guide to how long coffee keeps you awake explains how caffeine behaves in the body.

9. The Baba Budan story has a kernel of history – but seven beans didn’t create all modern coffee

The story of Baba Budan is another famous chapter in coffee history.

According to the traditional account, Baba Budan brought seven fertile coffee seeds from Yemen to India during the 17th century, helping establish coffee cultivation there.

The story has become an important part of Indian coffee history.

But the claim that every coffee plant in the world descended from those seven seeds goes too far.

Coffee spread through multiple routes.

Arabica plants and seeds travelled from Yemen through different pathways into India, Java and eventually other parts of the world.

So Baba Budan’s story is significant, particularly in the history of Indian coffee, but it shouldn’t be presented as the single origin of all coffee grown outside Arabia.

10. Where coffee grows is known as the Coffee Belt

Our final entry among these coffee facts takes us around the world.

One of the key geographical coffee facts is that most commercial coffee is grown in a broad region around the equator commonly called the Coffee Belt.

This includes coffee-producing countries across Central and South America, Africa and Asia.

Within that enormous area you’ll find dramatically different environments, elevations, soils, climates, coffee varieties and farming traditions.

That’s one reason coffee can produce such a wide range of flavours.

A coffee from Ethiopia might offer very different characteristics from one grown in Brazil, Colombia or Indonesia.

You can explore some of these differences in our guides to Ethiopian coffee, Brazilian coffee, Colombian coffee and Indonesian coffee.

How many of these coffee facts did you know?

The deeper you explore coffee, the more interesting it becomes.

A coffee bean is actually a seed. The famous Kaldi story is probably a legend. Bees can benefit coffee production. Yemen played a crucial role in coffee’s history, and coffee houses have been bringing people together for centuries.

Perhaps most importantly, coffee isn’t one uniform product.

Origin, species, variety, processing, roasting and brewing can all influence what’s in your cup.

These coffee facts only scratch the surface, but they’re a good reminder that every bag of coffee has a much bigger story behind it.
