Charcoal Companion Merlot Soaked Oak Wood Smoking Chips are a gourmet delight. Wood smoke adds to the mystique of outdoor cooking and gathers people around the fire. Adding wood chips and chunks boosts the flavor of any grilled food. On charcoal grills, wood chips can be used directly on the hot coals. Wood chunks can even be used instead of coals. On gas grills, add smoky flavor with the use of a smoker box for smoking wood chips.
