If you happen to have leftover wine (like this ever happens!) put it to good use. Freeze your wine in ice cube trays to use later. Frozen wine cubes are so handy and can be used in a variety of ways like in soups, sauces, glazes or even drinks. Use wine cubes instead of ice cubes in Sangria. Toss a couple of red wine cubes in your spaghetti sauce. Or toss a few white wine cubes in your chicken soup. Use the cubes for anything that you can think of that may need an additional layer of flavor. Never water down your wine again, pop a couple of wine cubes into your glass instead of ice cubes.
