To create the marinade, combine wheat beer, olive oil, lemon juice, minced garlic, sea salt, pepper, dry mustard, and dark chili powder in a medium-sized bowl and whisk until well incorporated.
Pour marinade into a 1-gallon resealable plastic bag, add pork chops, and seal.
Let pork chops marinate in refrigerator for 4-6 hours.
Preheat grill to high.
Remove pork chops from marinade and place on grill.
Grill over high heat 3-4 minutes per side, or until internal temperature reaches 145 degrees Fahrenheit, as per a meat thermometer.
Serve with a cold glass of wheat beer (optional).
