Preheat oven to 450 degrees Fahrenheit.
A few hours before roasting, remove meat from refrigerator to bring to room temperature.
In a food processor, blend coffee with salt and pepper to grind very finely. Rub mixture all around the meat.
Cover the tips of the bone with aluminum foil so they don’t burn. Roast meat, uncovered, for 15 minutes.
Reduce temperature to 325 degrees Fahrenheit and roast for an additional two and a half hours. Insert a thermometer into the thickest part of the meat. It should read 125 degrees Fahrenheit for medium-rare.
Transfer to a carving board and allow to rest 20 minutes before slicing.
