What is vacuum packaging in green coffee?

Vacuum packaging removes air from a sealed container or bag before closing it, reducing the oxygen available to react with the coffee. It's used to extend storage life and maintain freshness - particularly for high-value micro-lots or coffees held for extended periods.

Oxygen is one of the primary drivers of quality degradation in both green and roasted coffee. By removing it from the packaging environment, vacuum packing significantly slows oxidation, inhibits insect activity, and reduces moisture exchange. The coffee is effectively isolated from the ambient environment until the seal is broken.

Vacuum-packed green coffee is typically sealed in multi-layer foil bags or rigid containers. The shelf life advantage over standard GrainPro or jute packaging is meaningful for lots held for more than six months - which is why it's particularly common for importers storing specialty micro-lots before sale, or for small consignments sent by air freight where preserving freshness during transit matters.
