  • Roasted coffee and coffee roasting method
    Patent number: 6207211
    Abstract: A two stage coffee roasting process includes a first stage, green coffee beans are roasted for 5-15 minutes to a roast color of 30-50 Lu. In a second stage, the beans are further roasted for ½-3½ minutes to a roast color of 4-19 Lu. The roasted beans have a reduced density in the range of 0.27-0.38, and a roast color of 4-19 Lu. Analysis of sulfur compounds in the coffee aroma reveals a high level of methylmercaptan, a key compound for the pleasant aroma of freshly roasted and ground coffee. Coffee beans roasted in accordance with the present invention have a generally high titratable acidity at a given density and roast color.
