Coffee Bean

Coffee beans are the seeds of the coffee plant and the source of one of the world’s most popular beverages. These small, unassuming beans hold a complex world of flavors, aromas, and cultural significance within them. Let’s explore the fascinating journey of coffee beans from plant to cup.

What Are Coffee Beans?

Coffee beans are the seeds found inside the fruit of the coffee plant, known as coffee cherries. Despite being called “beans,” they are not legumes but rather the pit of the coffee cherry. There are two main commercially cultivated species of coffee plants:

1. Coffea arabica (Arabica coffee)
2. Coffea canephora (Robusta coffee)

Arabica beans are known for their superior flavor and account for about 60-70% of global coffee production, while Robusta beans have a more robust, harsher taste and higher caffeine content.

The Coffee Plant

Coffee plants are evergreen shrubs or small trees that thrive in tropical and subtropical regions. They require specific growing conditions:

• Altitude: typically 3,000-6,000 feet above sea level
• Temperature: between 60°F and 70°F
• Rainfall: about 60 inches per year
• Soil: well-draining, slightly acidic

A coffee plant’s first fruit is produced in about 3-4 years, and under ideal conditions, each plant can live up to 100 years.

From Cherry to Bean

The journey from coffee cherry to bean involves several steps:

1. Harvesting: Coffee cherries are picked when ripe, either by hand or machine.
2. Processing: The flesh of the cherry is removed, leaving the bean.
3. Drying: Beans are dried to reduce moisture content.
4. Milling: The protective parchment layer is removed from the bean.
5. Grading and Sorting: Beans are classified by size and quality.

Roasting Coffee Beans

Roasting is a crucial step that transforms the green coffee beans into the aromatic brown beans we’re familiar with. The roasting process involves:

• Heating beans to temperatures between 356°F and 446°F
• Causing chemical changes as sugars and amino acids react
• Developing the bean’s flavor, aroma, and color

Roasts are typically categorized as light, medium, medium-dark, and dark, each producing distinct flavor profiles.

Coffee Bean Varieties

There are numerous varieties of coffee beans, each with unique characteristics. Some popular ones include:

• Typica: The original Arabica coffee, known for its sweet, clean taste
• Bourbon: A mutation of Typica, with a balanced and complex flavor
• Gesha/Geisha: A rare, highly prized variety known for its floral and tea-like qualities
• Catimor: A hybrid of Arabica and Robusta, resistant to coffee leaf rust

• Employs over 125 million people worldwide
• Generates over $200 billion in annual revenue
• It is a crucial export for many developing countries
