                                A standard 3-liter boxed wine contains the equivalent of four 750ml bottles, yielding approximately 20 five-ounce glasses. However, this number is a baseline, and the actual quantity of glasses you get from a boxed wine depends on both the size of the box and the generosity of your pour.
