What is the San Jose Estate rum barrel fermented Castillo coffee?
San Jose Estate in Colombia ferments Castillo variety beans in rum barrels before drying. The process adds layers of flavor that a standard wash cannot reach. Where did coffee originate from? Ethiopia, but Colombia's Castillo variety was bred for disease resistance and has become a workhorse on many farms. The barrel fermentation steeps the beans in residual rum character, yielding a cup with brown sugar, dried fruit and a warm spirit note.
Colombian coffee beans characteristics usually include a balanced body, mild acidity and caramel sweetness. The Castillo variety fits that profile, and the rum barrel treatment pushes it toward rum raisin and molasses. Roasters should keep the roast light to medium so the fermentation flavors stay clear. Rest the beans a few days after roasting to let the alcohol-like aromatics settle before brewing.
