Why do the vast majority of wine bottles contain 75ml of wine?
Is there a historical reason for this (perhaps it’s related to the size of a flagon or summat?), or is it to do with tax/duty levied on amounts over 750ml?
750 ml was chosen because it’s very close to a fifth of a U.S. gallon, which is 757 ml. Before the change, the fifth was a common bottle size for wine and liquor.
[Aside] I worked for a duty-free company where 75cl and litre bottles of the same products (wines, spirits and liqueuers) were stocked - ‘bottle’ is the industry standard term for the 75cl measure.
