What to Look for in Green Bean Sources
Green bean quality varies dramatically. Specialty-grade green coffee (SCA score 80+) produces the complex, clean flavors that make home roasting worthwhile. Below this threshold, even a perfect roast can't overcome defective or poorly processed beans. The best green bean suppliers provide: SCA score or equivalent quality indicator, processing method (washed, natural, honey), region and often farm-level sourcing, harvest date, and recommended roast profile notes.

Generic "green coffee beans" on Amazon — provenance is rarely documented, SCA scores aren't provided, and quality is inconsistent. Grocery store "raw coffee beans" — same provenance issues. Wholesale sources without roasting guidance — fine for experienced roasters who know what they're buying; frustrating for beginners without tasting note context to calibrate expectations.
Natural (dry process) coffees for beginners: naturals are delicious when roasted well but roast faster, produce more chaff, and show defects more obviously. Start with washed Colombian or Brazilian beans — they're forgiving, consistent, and highlight roast progression clearly.
☕ Recommendation
Start with Sweet Maria's — the tasting notes and roast recommendations are invaluable for new home roasters. Buy 1 lb each of 2–3 different origins to compare how different beans respond to the same roast approach. Green beans store for up to 2 years in a cool, dark location.
