- Climate: Coffee grows best in tropical climates with temperatures ranging between 60°F and 70°F.
- Altitude: Higher altitudes often yield better quality coffee due to slower maturation rates, which enhances flavor profiles.
- Soil: Coffee plants prefer nutrient-rich, well-draining soil that supports healthy growth.
The most commonly cultivated coffee species are Arabica and Robusta. Arabica beans, often considered superior in taste, tend to have a more delicate flavor and are grown at higher altitudes, while Robusta beans are hardier and typically contain higher caffeine levels.
2. Coffee Cherry Harvesting
Once the coffee cherries are ripe, they need to be harvested.
Harvesting Methods
- Hand-Picking: This is the most common method for high-quality beans, allowing pickers to select only the ripe cherries amidst a field of varying maturities.
- Mechanical Harvesting: More prevalent in large plantations, this method uses machines to shake the trees and collect all cherries, regardless of ripeness.
While hand-picking ensures better quality, mechanical harvesting is faster and more cost-effective.
3. Processing Coffee Cherries
Post-harvest, coffee cherries undergo processing, which is vital to transforming them into the green coffee beans used in brewing. There are two main processing methods: wet and dry.
The Wet Method
This method involves removing the pulp from the cherries while they are still fresh.
- Fermentation: The cherries are soaked in water, allowing the mucilage to ferment and loosen, which is washed off afterward.
- Drying: The beans are then spread out in the sun or placed in drying machines until they reach the desired moisture content.
The Dry Method
In this method, cherries are spread out in the sun with their pulp intact.
- Drying: Over time, the cherries dry out naturally, which causes the outer layers to become brittle and easier to remove.
- Hulling: Once dried, the pulp and parchment skin are mechanically hulled to reveal the beans.
The choice of processing method can significantly impact the coffee’s flavor, cleanliness, and aroma.
4. Milling Green Coffee Beans
Once processed, the next step is milling. Milling is essential for achieving the uniformity and quality necessary for green coffee.
Milling Stages
- Hulling: Removing the parchment layer that surrounds the beans.
- Polishing: An optional procedure to enhance appearance, where any remaining husk is removed.
- Grading and Sorting: Beans are sorted based on size, weight, and quality. Defective beans are removed to ensure only the best go to market.
5. Quality Control and Exporting
Quality control plays a critical role in the production of green coffee.
Grading Systems
Green coffee is often graded using standardized systems, assessing factors such as:
