This struck me as funny. The quick answer: 2 The longer explanation: 750ml is 750 milli-liters. 1,000ml = 1 liter. So since 750ml plus 750ml would equal 1,500ml , that would also be 1.5 liters. Hope that helps.
As the amount of ounces per liter is 33.824 and 750ml is 33.824 x .75, then the ounces per 750ml bottle would equal 25.368 oz. Using the standard 5 oz glass, there are about 5 glasses per bottle of wine.
