How Long Do Green Coffee Beans Last Compared to Roasted?
Green beans last 10–20x longer than roasted coffee. This is one of the key practical advantages of home roasting — you can buy in bulk without staleness concerns.
⚡ Quick Answer
Green coffee beans: 1–2 years at good quality, up to 3+ years if stored in a cool, dark, dry environment in breathable bags (burlap or the original grain bag). Roasted coffee: 2–4 weeks at peak, 2–3 months acceptable. The difference is that green beans haven't undergone the chemical changes from roasting that accelerate oxidation and degassing. Humidity and heat are the main enemies of green bean storage.
🎯 Best Storage: Cool, dark location (under 21°C / 70°F). Original grain bags or breathable burlap. Avoid sealed airtight containers for long-term green storage — beans need to breathe and release CO₂. Avoid high-humidity environments (>65% RH).
