About the wine bottle

Standardisation of the 750 milliliter bottle is recent. Wikipedia does not explain why that figure was chosen, only that it has become the standard unit for wine sales. In the United States, bottles before 1979 followed the fifth, one fifth of a US gallon, about 757 mL. In 1979 the US adopted metric sizes for wine and spirits, making the basic bottle 750 mL as in Europe.

Larger formats are counted in multiples of this bottle: a magnum is two, a double magnum four and a Methuselah eight, while smaller ones include the half bottle of 375 mL and the 187.5 mL piccolo. A 750 mL bottle is exactly three quarters of a liter, roughly 25.4 US fluid ounces. Because the number is set by law for trade, a bottle sold today is the same size in Bordeaux, Napa or Sydney, whatever the shape of the glass.
