Whisk all of the marinade ingredients together in a glass bowl. Marinade chicken for at least 2 hours, or overnight in a vacuum seal bag.
Empty chicken and marinade into a bowl, and allow it to come to room temperature while you heat up the grill.
Heat grill to 450F over oak charcoal with chunks of mesquite. Keep at this temperature for 15 minutes with the lid closed and vented to heat the grates.
Using a long grilling fork or tongs, remove the chicken from the marinade and add it directly to the hot grates. Grill for 3 minutes.
Flip the chicken thighs, and grill for 3 minutes more.
Remove to a platter.
Tent with foil and rest for at least 5 minutes before serving.
