The Art of Coffee Roasting

Roasting is the source of coffee flavor. The process of fire-roasting green beans is called roasting. Unroasted green beans cannot be consumed for drinking. After roasting, coffee beans determine 80% of the coffee's taste. The roasting process is tricky - if the fire is too strong, the exterior will be cooked while the interior remains raw; if the fire is too weak, the interior will be overcooked while the exterior is properly done. The key is to control the heat properly to ensure coffee beans are roasted evenly inside and out.
