Coffee roasters are businesses or individuals that transform raw, green coffee beans into the aromatic, brown beans used to brew coffee. This process involves heating the beans in a machine called a roaster, which brings out their unique flavors and aromas. Roasting can vary in time and temperature, resulting in different roast levels, such as light, medium, or dark. Many coffee roasters also focus on sourcing high-quality beans from specific regions, often referred to as single-origin coffee. They may work directly with farmers to ensure fair trade practices and sustainable farming methods. This commitment to quality and ethics enhances the overall coffee experience for consumers.
