Preheat grill to 300 degrees. Spare ribs cook low and slow, so be sure to keep your temperature low throughout cooking.
Line a large pan with foil (or using a foil pan). Pat ribs dry with paper towel and rub seasoning onto both sides, pressing it firmly into the ribs.
Cover and refrigerate for 1 hour or overnight.
Pour apple juice and apple cider vinegar into the bottom of the pan and place ribs in. Cover with foil and grill for 2 hours, or until meat begins falling off the bone.
Be sure your grill grates have been cleaned from any residue. Remove ribs from pan onto a platter and drain the liquid, reserving 1 cup.
Transfer 1 cup liquid from bottom of cooking pan to a small pot. Turn the heat up to high, and boil until mixture is reduced by half. Whisk in bbq sauce.
Turn grill up to medium-high heat. Put the ribs directly on the grill and cook 5 minutes per side, or until browned and slightly charred.
Remove from grill and allow to rest 5 minutes. Brush each side with the bbq sauce mixture. Serve hot with additional bbq sauce.
