Wine bottle

A wine bottle is a bottle, generally made of glass, used for holding wine. Some wines are fermented in the bottle, others are bottled only after fermentation.

Recently the bottle has become a standard unit of volume to describe sales in the wine industry, measuring 750 millilitres (26.40 imp fl oz; 25.36 US fl oz). Wine bottles are produced, however, in a variety of volumes and shapes.

Wine bottles are traditionally sealed with cork, but screw-top caps are becoming popular, and there are several other methods used to seal a bottle.

Many traditional wine bottle sizes are named for Biblical kings and historical figures. The chart below lists the sizes of various wine bottles in multiples relating to a standard bottle of wine, which is 0.75 litres (0.20 US gal; 0.16 imp gal) (six 125 ml servings). The "wineglassful"—an official unit of the apothecaries' system of weights—is much smaller at 2.5 imp fl oz (71 ml).

Most champagne houses are unable to carry out secondary fermentation in bottles larger than a magnum due to the difficulty in riddling large, heavy bottles. After the secondary fermentation completes, the champagne must be transferred from the magnums into larger bottles, which results in a loss of pressure. Some believe this re-bottling exposes the champagne to greater oxidation and therefore results in an inferior product compared to champagne which remains in the bottle in which it was fermented.
