When it comes to quality coffee, controlling the roasting process is one of the most essentials steps in achieving the most desirable recipe. At the beginning of the roasting cycle, the green beans color starts to shift to yellow and then to increasingly darker shades of brown. This change in color shows the physical and chemical transformations that occur during roasting. The Photovolt 580-PC Roast Color Classification System assists during the roasting process by measuring the color of roasted whole or ground beans. The 580-PC is a reflectance meter that can be used at any stage during the roasting process to determine not only the reflectance value, but the relative SCAA (Specialty Coffee Association of America) number of the batch. Roast masters find it easier to follow their roast profile and create consistent batches with the help of the 580-PC. Many roastmasters judge roast color by eye, which can lead to inconsistencies. The 580-PC is specifically designed to measure ground or whole roast coffee beans. Photovolt’s instruments are all NIST traceable, which means the measurement of color you receive is traceable to the National Institute of Standards and Technologies in Washington D.C.. Different from similar products in the marketplace, such as Agtron, the Photovolt 580-PC provides the most accurate, precise reading possible.
