Prepare your grill for medium heat and indirect cooking.
In a small bowl, mix together the garlic powder, cumin, salt, and pepper. Rub the mixture over both sides of the ribs.
Oil the grill, place ribs meat side down on grill and cook 30 minutes. Turn ribs over and cook 30 minutes.
While the ribs are grilling, in a saucepan, add the lager, preserves, and honey. Place on medium high heat and bring to a boil. Cook for 20 minutes, stirring often, until the mixture is thick and reduced to 3/4 cup.
Turn the ribs over, brush with ½ the glaze and grill for 15 minutes. Turn ribs over and brush with remaining glaze and grill for another 15 minutes or until ribs are tender.
Transfer ribs to a serving tray and enjoy with sides of your choice.
