Cut off the top 1/4 to 1/2 inch of each garlic bulb to expose the cloves. Remove the papery outer skins, leaving the cloves intact. Place each garlic bulb on a 6-inch square of heavy foil; drizzle bulbs with olive oil. Wrap foil up around bulbs; seal. For a charcoal grill, grill garlic on the rack of an uncovered grill directly over medium coals about 25 minutes or until garlic is soft. (For a gas grill, preheat grill. Reduce heat to medium. Place foil-wrapped garlic bulbs on grill rack over heat. Cover and grill as above.) Remove garlic from grill and cool slightly.
Meanwhile, in a medium bowl, combine coffee crystals, cocoa powder, chili powder and salt. Stir in whiskey or water. Add venison; mix well. Shape into four 1/2-inch-thick patties.
For a charcoal grill, grill patties on the greased rack of an uncovered grill directly over medium coals for 10 to 13 minutes or until an instant-read thermometer inserted into side of each patty registers 160 degrees F, turning once halfway through grilling. (For a gas grill, place patties on grill rack over heat. Cover and grill as above.)
Meanwhile, squeeze garlic cloves from the skins into a small bowl. Mash garlic with a fork. Spread garlic on bun bottoms; add lettuce (if using) and grilled patties. If desired, top with chile peppers, tomato, red onion and/or pickles. Add bun tops.
