About Robusta Green Coffee Beans

Common Varieties and Grades

Robusta green coffee beans are categorized primarily by screen size, defects, and origin. Common grades include:

• Screen Size: Graded by the size of the bean using sieves, e.g., Grade 15+, Grade 16+, where the number represents the screen size in 64ths of an inch.
• Defects: Beans are sorted to remove defects such as black beans, broken beans, and foreign materials to ensure quality.
• Origin-based grades: Beans sourced from Vietnam, India, Indonesia, or Uganda may carry specific regional distinctions.

These grading standards ensure that green beans meet quality benchmarks for flavor, density, and roasting consistency.

Technical and Nutritional Properties

Robusta green coffee beans are notable for their chemical composition and physical characteristics:

• Caffeine Content: Approximately 2.2% to 2.7%, contributing to a strong bitterness and stimulating effects.
• Chlorogenic Acids: Higher levels than Arabica, impacting antioxidant activity and flavor complexity.
• Moisture Content: Typically maintained between 10-12% for optimal storage and roasting performance.
• Density: Generally denser than Arabica beans, affecting roasting time and temperature.

These factors influence the roasting profile, taste outcome, and shelf life of the final coffee product.

Harvesting and Production Process

Robusta coffee is harvested primarily via selective hand-picking or strip harvesting in large plantations. The harvesting season varies by region but usually aligns with local wet and dry seasons.

After harvesting, green coffee beans undergo processing either by the dry (natural) method or wet (washed) method:

• Dry Processing: Beans are dried in the sun with the coffee cherry intact, which imparts a heavier, earthier flavor.
• Wet Processing: The fruit pulp is removed before drying, producing a cleaner cup with brighter acidity.

Once dried to appropriate moisture levels, beans are sorted, graded, and packed for export, ensuring preservation of quality.

Applications and Uses

Robusta green coffee beans are widely used for:

• Espresso Blends: Providing crema, body, and caffeine punch in blends with Arabica.
• Instant Coffee Production: Due to robust flavor and solubility characteristics.
• Commercial Coffee Roasting: For a strong, bold cup favored in many markets worldwide.
• Specialty Coffee Products: Including extracts, supplements, and functional beverages.

Quality, Packaging and Export Information

Quality assurance in Robusta green coffee beans involves strict sorting, moisture content control, and defect removal to meet industry standards such as those of the ICO (International Coffee Organization) and specialty coffee associations.

Packaging is typically done in multi-wall paper bags lined with polyethylene, weighing 60 kg net per bag. These are stacked on pallets for efficient shipment and storage, helping preserve freshness and prevent contamination.

The beans are exported worldwide, often stored in controlled environments during transit to maintain quality until they reach roasters and distributors.
