The two species of commercial coffee trees most widely grown are coffea arabica and coffea canephora (referred to as robusta). The robusta species is grown at lower altitudes and produces a lower quality bean that is the main component in commercial canned coffees. Generally, robustas have an earthy flavor. The cleaner flavor of the arabica bean is at the center of the specialty coffee movement. These higher quality beans are prized by both coffee experts and coffee lovers alike. La Torcaza Estate is only high-quality arabica beans.
