1. Combine coffee, brown sugar, allspice, salt and pepper to taste. Pat rub on both sides of each steak.
2. Prep grill for cooking over indirect heat. You'll need a medium-high temperature of around 350°F (180°C) to grill steaks. For natural gas grills, preheat grill to medium-high and turn off one burner to achieve indirect heat.
3. Grease grate with canola oil. Place steaks on grill over direct heat. Cook for four to five minutes per side, or until well-marked. Move steaks to the cooler part of the grill and close lid. Cook for two to three minutes for medium-rare, or to the desired tenderness.
4. Remove steaks from grill and let rest for five minutes before serving.
