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.
