Green Coffee Screen Distribution: What Cambodian Coffee Buyers Should Track

Screen distribution describes the size mix in a green coffee lot. For Robusta Cambodia, it can help buyers understand preparation consistency and predict how evenly beans may respond during roasting.

Uniformity can simplify roasting

A lot with a very broad size range may contain beans that absorb and release heat differently. This does not automatically make the coffee poor, but it can make roast development harder to control. Buyers should decide how important size uniformity is for the intended product.

Do not confuse bigger with better

Large beans are not automatically more flavorful. Screen size is a physical specification, not a sensory score. A smaller, well-processed lot can outperform a visually impressive but poorly handled coffee.

Track distribution, not one number

Instead of asking only for “screen 16,” buyers can request the percentage retained across relevant screens. That gives a clearer picture of the lot.

Use screen data with

• Moisture
• Density
• Defect analysis
• Roast behavior
• Cup results
• Final application

Robusta Cambodia buyers should use screen distribution to improve consistency, not as a shortcut for judging origin quality.
