In the bottom of a Dutch Oven, slice the onions and place brisket on top of them.
Mix the ketchup, onion soup mix, ginger ale and wine together and pour them over the meat. Note:If you want more gravy, you can add more ginger ale or water.
Cook for 2-3 hours until fork tender either in top of the stove or in a 350 degree F. oven. If you place meat in the oven, make sure your Dutch oven doesn't have a plastic knob on the lid (like mine does).
