Mix beer and ketchup. Add onion soup and brown sugar into beer mix. Pour over the washed brisket and roast at 300 degrees, at least, 30 minutes per pound, checking regularly and adding water into the pan (not over the brisket) as needed.
Sprinkle dry soup mix and garlic over brisket. Arrange onion rings and celery stalks on top. Combine chili sauce, beer and water, pour over meat. Bake covered in preheated 350 degree oven, allowing about 40 minutes per pound. Baste occasionally with liquid. The last 45 minutes, take the cover off and let brown.
