Combine the marinade ingredients in a bowl and whisk together. Remove half of the marinade and set aside for basting the chicken while it grills.
Place the chicken in a large resealable bag and pour the marinade over the top. Seal the bag securely and massage the marinade into the chicken.
Chill the chicken in the refrigerator and at least 30 minutes or up to 4 hours. For the most flavor, 2 to 4 hours is optimum.
To Grill
Preheat the grill to medium high heat (about 400 degrees) and lightly oil the grates.
Remove the chicken from the marinade and discard the remaining marinade.
Place chicken over direct heat and grill for 6 to 8 minutes per side. Once the chicken reaches an internal temperature of 160°F, move the thighs to a low heat zone of the grill. As the chicken grills, baste with reserved marinade.
When cooked, remove chicken from the grill, tent with foil, and let rest about 5 minutes before serving.
