Cover beans with water and soak overnight. Heat oven to 350 degrees F. In a large Dutch oven, or kettle with lid, combine drained beans, the 6 cups water and all remaining ingredients. Bring to a boil, skimming if necessary. Cover and transfer to oven. Bake 1 1/2 hours, remove cover and bake another 30 minutes; stirring occasionally. Serve immediately or cool slightly, cover and refrigerate overnight. Remove any fat from surface; reheat slowly on stovetop over medium-low heat, stirring occasionally.
