If using wooden skewers, soak for 1hr. before using. Preheat grill to med-high heat. Salt and pepper scallops. Combine coffee and syrup and brush each piece of bacon on both sides. Wrap one piece of bacon around each scallop and secure on skewers(2-3 per skewer). Grill for about 5 minutes, turning once until scallops are done and bacon is starting to crisp. Could also prepare under broiler.
