From Plant to Cup || The Worldly Adventure of Coffee Beans

Coffee trees are pruned to a shorter height for energy conservation and ease of harvesting, although they have the potential to grow over 30 feet (9 meters) tall. Covered in green, waxy leaves arranged in opposing pairs, these trees bear coffee cherries and coffee beans along their branches. The growth cycle results in simultaneous appearances of flowers, green fruit, and ripe fruit on a single tree.

It takes nearly a year for a coffee cherry to fully mature after the initial flowering and approximately five years for the tree to achieve maximum fruit production. While coffee plants can endure for up to a century, their peak productivity typically occurs between 7 and 20 years of age.

Proper care can maintain or even enhance their output over time, depending on the specific variety. On average, a coffee tree yields 10 pounds of coffee cherry annually, equating to 2 pounds of green beans.

All commercially cultivated coffee originates from the Coffee Belt, a region characterized by rich soil, mild temperatures, frequent rainfall, and filtered sunlight—conditions optimal for coffee tree growth.

Definition of Coffee Beans and Their Source from the Coffea Plant

Coffee beans are the seeds found inside the fruit of the coffee plant, known as the coffee cherry. The Coffea plant, a member of the Rubiaceae family, is a tropical evergreen shrub or small tree. There are several species of Coffea, but the most commonly cultivated for coffee production are Coffea arabica and Coffea robusta.

The coffee beans are typically located at the centre of the coffee cherry, nestled within the pulp, and surrounded by a protective layer called parchment. These beans are the raw material for the coffee we enjoy, and they undergo a series of processes before reaching our cups.

Explanation of the Term “Coffee Cherry” and the Stone Fruit Analogy

“Coffee cherry” describes the fruit that houses the coffee beans. The coffee cherry is a small, round, and usually red or purple fruit resembling a cherry, hence the name. It consists of several layers:

1. Skin/Exocarp: The outermost layer, which is thin and smooth.

2. Pulp/mesocarp: A thicker layer beneath the skin containing a sweet, gummy substance.

3. Mucilage: A sticky layer surrounding the beans.

4. Parchment/Endocarp: A protective layer covering the actual coffee beans.

The stone fruit analogy helps to clarify the structure of the coffee cherry. Similarly to how a peach or cherry has a pit or stone at its centre, the coffee cherry has beans at its core. The analogy emphasises that, like peaches and cherries, coffee cherries are a type of fruit, and the beans inside are seeds.

Clarification on the Misconception of Coffee Beans Being Actual Beans

Despite being called “beans,” coffee beans are not true legumes like soybeans or peas. Legumes are seeds that develop in pods, while coffee beans develop within a fleshy fruit. The term “bean” is a historical misnomer that likely originated due to the physical resemblance of the coffee bean to true legumes.

In botanical terms, coffee beans are seeds; their classification as beans is a linguistic convention rather than biological. Understanding this distinction is crucial for appreciating the unique journey and cultivation process that coffee undergoes from the coffee plant to your morning brew.
