Green coffee beans are raw, unroasted coffee seeds extracted from coffee cherries. They are exported in this "green" state because they have a much longer shelf life than roasted coffee (12-24 months vs. weeks), are easier to transport in bulk, and allow buyers to roast according to their specific requirements and market preferences.

Technical specifications create a standardized language between buyers and sellers across different countries and cultures. They help ensure quality consistency, facilitate fair pricing based on objective criteria, reduce disputes through clear expectations, enable quality comparison between suppliers, and meet regulatory requirements in importing countries. Without clear specifications, international trade would be inefficient and risky for both parties.

Coffee beans are classified using multiple criteria: Size is measured using screens (perforated metal sheets) with holes of specific diameters - Screen 18 means beans are retained by a screen with 18/64-inch holes. Defects are counted and categorized by type and severity. Moisture content is measured using electronic moisture meters. Color is assessed visually or with colorimeters. Cup quality is evaluated through professional cupping sessions following standardized protocols.

Moisture content directly impacts coffee shelf life, quality stability, and even safety. Too high moisture (>13%) creates risk of mold growth, bacterial contamination, premature aging, and off-flavors. Too low moisture (<9%) can cause beans to become brittle and lose flavor compounds, and reduce weight (affecting commercial value). The 9-12.5% range maintains stability while preserving the beans' intrinsic quality characteristics throughout storage and transportation.

Black/Sour beans create harsh, fermented, or medicinal flavors in the cup. Broken beans roast unevenly and can contribute bitterness. Insect-damaged beans produce unclean flavors and reduce overall cup quality. Immature beans lack sweetness and contribute astringency. Foreign material doesn't affect flavor directly but indicates poor quality control. Even small percentages of defects (1-2%) can noticeably impact cup quality, which is why premium grades specify very low defect tolerances.

Standard jute bags (60kg) are traditional and economical for most shipments. GrainPro liners inside jute bags provide superior moisture protection for premium coffees or long sea voyages. Vacuum-sealed bags offer maximum protection but are more expensive and used for small quantities or samples. Super sacks (bulk bags) of 1000kg+ are efficient for large-volume commercial shipments. The best option depends on your budget, destination, shipment duration, and quality level. For specialty coffees or humid destinations, GrainPro liners are highly recommended.

Phuoc Son can provide various certifications based on customer requirements, including Organic, Fair Trade, 4C, and ISO 22000 food safety certification. We work directly with certified farmers and maintain proper chain-of-custody documentation. Not all certifications are available for all products - please contact us to discuss specific certification needs for your target markets.

Our quality assurance includes: Direct relationships with certified farmer cooperatives, modern processing facilities with optical sorting technology, multiple quality control checkpoints from receiving to final packing, trained staff for professional cupping evaluation, pre-shipment samples and inspection reports, moisture and defect testing on every lot, and complete traceability from farm to container. We view quality as a partnership with our customers and stand behind every shipment with transparent documentation and responsive support.

You can request detailed specifications through our B2B contact form below, by emailing us directly, or through WhatsApp. We provide comprehensive specification sheets including: physical characteristics (screen size, moisture, defects), cupping scores and flavor notes, processing method and origin details, available certifications, packaging options, pricing and minimum order quantities, and sample availability. We're happy to discuss custom specifications to match your exact requirements.

While both varieties share similar specification frameworks (moisture, defects, size), Arabica typically commands stricter standards due to its specialty market positioning. Arabica is graded with more detailed defect classifications, generally requires lower moisture content (8-11%), has different screen size ranges (14-17 for Arabica vs. 13-18 for Robusta), and undergoes more rigorous cupping evaluation. Robusta specifications focus more on consistency and processing quality. Phuoc Son specializes in both varieties and can provide detailed grade descriptions for each.
