Add the wine, let it simmer until it has evaporated, then add the tomato sauce and stir thoroughly to coat all ingredients well. When the tomatoes begin to bubble, turn the heat down to the lowest so that the sauce cooks at the laziest of simmers, with just an intermittent bubble breaking through to the surface. Cook, covered, for 3 hours or more, stirring from time to time. While the sauce is cooking, you are likely to find that it begins to dry out and the fat separates from the meat. To keep it from sticking, add 1/2 cup of water (or beef stock or vegetable stock) whenever necessary. In the end, however, no water at all must be left and the fat must separate from the sauce. Taste and correct for salt.
