Definition

Pale roasted beans that failed to brown normally, often linked to immature or poorly developed green coffee.

Why it matters

Recognizing the defect helps separate green-coffee limitations, heat-transfer problems and profile errors.

How it is measured or recognized

Inspect a representative cooled sample under consistent light, then confirm impact through blind cupping.

Roasting tip

Investigate the complete batch record before changing one control; similar symptoms can have different causes.
