A wine bottle is a bottle used for holding wine, generally made of glass. Some wines are fermented in the bottle, others are bottled only after fermentation. They come in a large variety of sizes, several named for Biblical kings and other figures. The standard bottle contains 75 cL, although this is a relatively recent development. Wine bottles are usually sealed with cork, but screw-top caps are becoming popular, and there are several other methods used to seal a bottle.The chart below expresses the sizes of various wine bottles in multiples relating to a standard bottle of wine, which is 0.75 litres (0.20 U.S. gal; 0.16 imp gal) .For many years, the U.S. standard (non-metric) wine and liquor bottle was the "fifth", meaning one-fifth of a U.S. gallon, or 25.6 U.S. fluid ounces (757 ml; 26.6 imp fl oz). Some beverages also came in half-gallon and one-gallon sizes. In 1979, the U.S. adopted the metric system for wine bottles, with the basic bottle becoming 75 cl, as in Europe.
