“Coffee is made from beans”

Many people commonly refer to the small, roasted kernels that brew our beloved morning beverage as "coffee beans," but this widely accepted term is actually a botanical misnomer. The truth is that these are not true beans in the horticultural sense, which belong to the legume family. Instead, they are the pits or seeds found within the vibrant, cherry-like fruit (Review) of the coffee plant.

Scientifically speaking, coffee plants produce drupes, which are fruits characterized by a fleshy outer part surrounding a shell or pit with a seed inside. In the case of coffee, this fruit is often called a coffee cherry. Each cherry typically contains two seeds, which, after processing and roasting, become the familiar "beans" we use. The resemblance to true beans, like kidney beans or black beans, is purely superficial, stemming from their shape and size rather than their botanical classification.

The widespread belief that coffee comes from beans likely originates from this strong visual similarity and the convenience of a simple, descriptive term. Over centuries of cultivation, trade, and consumption, the colloquial "coffee bean" became deeply ingrained in our language and understanding. This common nomenclature, while technically incorrect, has persisted because it's intuitive and doesn't hinder the enjoyment or preparation of the drink, making it one of those charming linguistic inaccuracies we've all come to accept.
