What is the difference between #lightroast and #darkroast #coffee? Is one superior to the other? Nowcado turned to the Zagat website for insights. A light roast allows the origin of the beans to shine through, so if you are partial to Ethiopian bean or a specific Guatemalan bean, then you’ll want a lighter roast. Lighter roasts tend to be brighter or more acidic. A darker roast takes on the flavors from the roasting process, so if you want a more full body flavor you may want to go darker. For the average coffee drinker, a medium roast is the perfect combination of flavor, acidity, and body. What coffee roast is your go-to?
