History

Before the mid 19th century, the capacity of British alcohol bottles used for wine and distilled liquors was nominally a quart, but the actual capacity varied considerably. Four primary styles existed, with different average capacities: 759±27 ml (715-810 range); 781±47 ml (724-880); 808±49 ml (739-835); ~1130 ml "imperial wine quart". Beer and cider bottles had a different range of sizes. In 1842, it was reported that ordinary wine bottles were 1/6 of an imperial gallon, that is, 758 ml. In the late 19th century, liquor in the US was often sold in bottles which appeared to hold , but in fact contained less than a quart and were called "fifths" or commercial quarts.Municipal League of Los Angeles, ''Municipal Affairs'' 2:1 (January 1907

/ref> At this time, one-fifth of a gallon was a common legal threshold for the difference between selling by the drink and selling by the bottle or at wholesale, and thus the difference between a drinking saloon or barroom and a dry-goods store. The fifth was the usual size of bottle for distilled beverages in the United States until 1980. Other authorized units based on the fifth included pint, called a tenth, and pint. During the 1970s, there was a push for

Wine also has a standard 187 ml (6.3 fl. oz.) measure and uses 1.5 liters (a magnum) instead of 1.75.
