70cl and 750ml bottles may appear similar, yet each serves different functions within industry. Here is their explanation:
Conversion: One 70cl bottle equals 700ml while 750ml bottles are sometimes known in America as “fifths”, or as standards.
Historical Context: For decades now, the U.S. liquor regulations from the late 19th century have dictated 750ml bottles as standard bottles; in Europe however, 70cl has become the go-to size because EU regulations strive for consistency within spirits markets using their metric system, while American drinkers still prefer imperial units like the 750ml option.
