Green Coffee Beans for Home Roasting
Your complete guide to buying, storing, and selecting green coffee beans. Learn where to source quality beans and how to keep them fresh for months.
What Are Green Coffee Beans?
Green coffee beans are raw, unroasted coffee seeds. They have a pale green color, a grassy smell, and a much longer shelf life than roasted coffee—up to 12 months when stored properly. This makes them perfect for home roasters who want fresh coffee on demand.
When you buy green beans, you're getting the same product that professional roasters start with. The difference is you control the roast level, bringing out the flavors you prefer—whether that's a bright, acidic light roast or a rich, chocolatey dark roast.
Key advantage: Green beans cost 50-60% less than roasted coffee. You pay $15-25/kg instead of $40-60/kg for specialty grade.
What to Look For When Buying
Origin & Altitude
High-altitude beans (1,200m+) generally have more complex acidity and flavor. Ethiopian beans are known for fruity, floral notes. Colombian for balance. Brazilian for chocolate and nuttiness. Kenyan for bright, wine-like acidity.
Processing Method
Washed (wet) processing creates cleaner, brighter flavors. Natural (dry) processing adds fruity, fermented notes. Honey processing falls between. Each suits different roast styles and taste preferences.
Crop Year
Look for current crop year beans (ideally within 6-12 months of harvest). Green coffee doesn't spoil but loses vibrancy over time. Fresh crop beans roast more evenly and cup better than old stock.
Grade & Defects
Specialty grade means fewer defects and better cup quality. Screen size (e.g., 17/18) indicates bean size consistency. Avoid beans with visible insect damage, mold, or discoloration.
Where to Buy Green Coffee Beans
These are the local sellers we track — importers and shops in each country that already brought the beans in. Each card opens our notes; you buy direct from the supplier. Always verify prices on the shop itself.Full supplier catalogue

💡 Pro Tip
Many local roasters will sell you green beans if you ask—they often have more than they can roast. This supports local business and gives you access to curated, high-quality beans. Just call and ask: "Do you sell green beans for home roasting?"
How to Store Green Coffee Beans
Green coffee is remarkably stable but still needs proper storage to maintain quality. The enemies are heat, moisture, and oxygen. Here's how to keep your beans fresh for months:
Temperature
Store at room temperature (15-25°C). Avoid garages and attics that get hot.
Humidity
Keep below 60% humidity. Use airtight containers in humid climates.
Light
Store in opaque containers or dark cupboards away from direct light.
Best Storage Containers
- • Food-grade buckets with gamma seal lids (bulk storage)
- • Mason jars with tight seals (small quantities)
- • Vacuum-sealed bags (long-term storage)
- • Original jute/burlap bags (if dry climate, short-term)
