Green coffee chemistry & aging

Assessing age vs quality trade-offs

Assessing age vs quality trade-offs

This topic explains how to evaluate the trade-offs between the age of green coffee and its quality, how storage conditions influence these trade-offs, and how buyers and roasters make decisions about usability and value.

Preservation strategies

Preservation strategies

This topic explains the key strategies used to preserve green coffee quality during storage and transport, focusing on packaging, climate control, and handling practices that slow aging and staling.

Sensory changes with aging

Sensory changes with aging

This topic explains how the sensory profile of coffee evolves with aging in storage, what chemical changes drive these shifts, and how they influence marketability and cup quality.

Impact of age on roast behavior

Impact of age on roast behavior

This topic explains how the age of green coffee affects roasting performance, physical transformations, and flavor outcomes, and why roasters carefully track bean age when designing roast profiles.

Bag permeability and oxygen ingress

Bag permeability and oxygen ingress

This topic explains how the permeability of coffee storage bags affects oxygen exposure, why it accelerates staling, and how different packaging choices influence quality preservation.

Storage temperature and shelf life

Storage temperature and shelf life

This topic explains how storage temperature affects the shelf life of green coffee, the chemistry behind flavor loss, and the best practices to preserve freshness and quality.
