Blueberry flavors in coffee take different forms. Dried blueberry was something we first encountered in natural Harar coffee from Ethiopia. It seemed to be most potent in fresh new crop coffees and would fade in several months. We don’t find this in Harar any more… but in other Ethiopia Naturals from the south we still encounter it. There can be a fresh blueberry note found in wet process coffees, and we have most often encountered it in Kenya coffees.
Since there aren’t blueberries widely available in Africa, tasters from there will find other flavors to describe it, since it is not a part of their flavor vocabulary most often.
