According to researchers, regular or conventional coffee is steeped in pesticides and other chemicals. The result of a study conducted by CS Monitor found that over 250 pounds of chemical fertilizers are being used to grow regular coffee. It suggests that in one cup of coffee, there could be over 1,000 chemicals present that can be linked to illnesses and health issues.
The next step in the quest for a quality cup of coffee is roasting. The roasting process heats up the beans at temperatures of 230 degrees Celsius; neutralizing the extreme unpleasant flavor profiles of the bean. The newly roasted bean offers nutty, smoky, or spicy flavors. The length of time that the bean is roasted determines the flavor profile and caffeine content. Beans roasted longer have a shiny black appearance and they boast a bitter and bold taste. Also, they are noted by an oily feel. Light roasted beans, which are roasted for a shorter length of time, tend to be sweeter, smoother, and even floral in flavor. If you prefer a lighter smooth taste, you will defer from bolder, darker roasts of equal of even better quality.
Over the course of the year, we reviewed fewer than a dozen darker roasts. Most were medium-dark at best; some barely that. The majority of darker roasts we reviewed were sent by roasters in Taiwan and most were espressos, reflecting both the time-honored espresso practice of emphasizing chocolate and sweetness through moderate dark roasting, as well as, perhaps, a preference in Taiwan for more traditional styles of espresso as opposed to the lighter-roasted, brighter style of espresso now popular with the leading edge of North American roasters.
