In the case of over half of the Top 30 coffees, distinctive tree variety appears to play an important role in generating an exceptional cup worthy of a high rating. There are stars and superstars among the hundreds of varieties of Arabica grown in the world today, and, whether we want them to or not, coffees from these distinguished varieties frequently dominate the very highest ratings at Coffee Review. They include the still rare and expensive Geisha/Gesha variety (three examples on the 2018 list), the various mainly indigenous varieties grown in Ethiopia (three on the 2018 list), the great SL28 and SL34 varieties of Kenya, and (slightly less distinctive but still likely to impress) the big-beaned varieties Maracaturra (one), Maragogipe (one) and the ancient heirloom Bourbon (four on the 2018 list).

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.
