The Journey of a Coffee Bean
An interactive guide to the intricate process of coffee cultivation and processing, from a cherry on a farm to the aromatic cup in your hands.
The Foundation: Cultivation on the Farm
Coffee’s story begins with a delicate plant that requires specific conditions to thrive. The two dominant species, Arabica and Robusta, have unique characteristics that define the global market.
Global Species Market Share
Arabica’s nuanced flavor makes it the market favorite, while Robusta’s resilience and caffeine content are vital for specific blends.
The “Bean Belt”
Coffee flourishes in an equatorial band with specific environmental conditions. Key requirements include:
- 🌡️ Temperature: Stable, mild temperatures (18-24°C for Arabica), with no frost.
- 💧 Rainfall: 1500-2500 mm annually, with distinct wet and dry seasons.
- ⛰️ Altitude: High altitudes (1000m+) for complex Arabica, lower for hardy Robusta.
- 🌿 Soil: Rich, well-drained volcanic soil is ideal.
The Critical Pick: Harvesting
After 7-11 months of ripening, the coffee cherries are ready. The harvesting method is a crucial decision that balances cost, efficiency, and the ultimate quality of the coffee.
Selective Picking
Harvesters pass through the farm multiple times, picking only the perfectly ripe cherries by hand. This yields the highest quality but is extremely labor-intensive and expensive.
- ✔ Highest Quality & Uniformity
- ✖ Very High Labor Cost
Strip Picking
All cherries are stripped from a branch at once, either by hand or machine. This is highly efficient but results in a mix of ripe and unripe cherries, requiring more sorting later.
- ✔ Highly Efficient & Low Cost
- ✖ Lower Quality & Consistency
The Art of Processing
This is where flavor is truly defined. The chosen method for removing the fruit from the seed (the bean) has the single greatest impact on the final taste profile. Click each method to see its process and flavor result.
Washed (Wet)
Fruit is washed off before drying. Highlights the bean’s intrinsic flavor.
Natural (Dry)
The entire cherry is dried. Imparts heavy fruit flavors to the bean.
Honey
A hybrid method balancing sweetness and clarity.
Final Prep: Milling & Export
After drying, the green beans are milled to remove any remaining layers, then rigorously sorted by size, density, and for defects. Only then are they bagged and exported globally.

The Transformation: Roasting
Roasting is a chemical alchemy where green beans are transformed, developing hundreds of aromatic compounds. The roast level determines the final flavor profile.
