Preheat oven to 300F.
Place ribs in a roasting pan and sprinkle them all over with salt and pepper. Pour the beer around them and cover the pan with foil.
Roast for 2 and a half hours or until tender. Cool. Recipe can be prepared to this point ahead and then refrigerated for a few days before finishing.
Preheat a grill on high heat.
Transfer ribs to a platter and pour cooking liquid into a small saucepan over high heat. Whisk in the garlic, gochujang, honey, fish sauce and soy sauce. Boil until thickened, about 5 minutes.
Brush ribs with some of the sauce and grill them for 3 minutes per side, basting them with more sauce as they cook. Serve with extra sauce on the side.
