What Is a Coffee Bean? The Truth About Coffee Cherries

You’ve heard the term ‘coffee bean’ your whole life—but have you ever wondered why we call it a bean at all? Most coffee drinkers assume they’re brewing seeds straight from the coffee tree. But there’s more to the story, and understanding what’s really inside that roasted puck starts with the fruit it came from.

In short: a coffee bean is not a bean. It’s the seed inside a fruit called the coffee cherry. Each cherry usually holds two seeds that look like beans—but roughly 5% are single round seeds, known as peaberries. That’s the real origin of your cup.

What Is a Coffee Cherry?

The coffee cherry is the fruit produced by the coffee plant. When ripe, it turns a red to purple color—hence the name. But contrary to common belief, the part we call the ‘coffee bean’ is actually the seed inside this fruit. It’s surrounded by layers of pulp, mucilage, parchment, and silver skin before roasting. What you see in the bag is just the inner seed, stripped of its fruit layers.

What Is a Coffee Bean Really?

A coffee bean is the seed of the coffee cherry. Though commonly referred to as a bean due to its shape, it is botanically a seed with an endosperm—just like a Brazil nut or grain of rice. These seeds are found inside the coffee cherry, which grows on coffee plants. Most cherries contain two seeds, but a small percentage have just one, rounded seed.

Why Do Some Coffee Cherries Have One Seed?

About 5% of coffee cherries develop a single, rounded seed instead of the usual two flat ones. This unique seed is called a peaberry—or caracol in Spanish. Unlike the typical flat-sided seeds, peaberries are small, round, and often considered to roast more evenly. While some believe they have a different flavor profile, this is debated among roasters and not universally agreed upon.

How Much Coffee Do People Really Drink?

Coffee is one of the most consumed beverages in the world, especially in developing countries, where it can represent over 50% of agricultural exports. The United States is the largest importer of coffee globally. In 2009, the average American consumed 4.09 kilograms (about 9 pounds) of coffee per year. That’s a lot of roasted seeds from a lot of coffee cherries.
