How many drinks does a bottle of vodka make?
A fifth makes about 17, a quart about 25, and a half gallon about 50.
A 26 oz. (750 ml) bottle of vodka yields 17 Servings of 1 ½ oz. (45 ml) each. A 40 oz. (1.14 L) bottle of vodka yields 25 Servings. The average cocktail party lasts three hours. Allow three drinks per person, more, depending on your guests' drinking habits. A buffet or sit-down dinner is usually about four hours long. Figure three to four drinks per person.
