Cook bacon in a skillet until fairly crisp. Remove the bacon but leave enough bacon grease to brown the meat. Brown the beef cubes in the bacon grease and place in slow cooker. Brown the carrots and onions in bacon grease and add to slow cooker. If you do not have enough drippings left, you may have to add butter. Add the flour to this. Then add the consomme, wine, tomato juice and seasonings.
