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.
Green coffee
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
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
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.
Water activity and microbial risk
This topic explains the role of water activity (a-w) in green coffee, how it influences microbial growth, and why controlling it is essential for food safety and quality preservation.
Oxidation and staling pathways
This topic explains how oxidation and staling occur in green coffee, the chemical pathways involved, and their impact on flavor, quality, and shelf life.
