Wine bottle

A wine bottle is a bottle, generally a glass bottle, that is used for holding wine. Some wines are fermented in the bottle while 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 a 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.

* For many years, the US standard (non-metric) wine and liquor bottle was the "fifth", meaning one-fifth of a US gallon, or 25.6 US fluid ounces (757 mL; 26.6 imp fl oz). Some beverages also came in tenth-gallon [12.8 US fluid ounces (379 mL; 13.3 imp fl oz)], eighth-gallon [1 US pint, or 16 US fluid ounces (473 mL; 16.7 imp fl oz)], sixth-gallon [22 US fluid ounces (651 mL; 22.9 imp fl oz)], fourth-gallon [1 US quart, or 32 US fluid ounces (946 mL; 33.3 imp fl oz)], half-gallon [64 US fluid ounces (1,890 mL; 66.6 imp fl oz)] and one-gallon [128 US fluid ounces (3,790 mL; 133 imp fl oz)] sizes. In 1979, the US adopted the metric system for liquor bottles, with the basic wine bottle becoming 750 mL, as in Europe.

Wine producers in Portugal, Italy, Spain, France and Germany follow the tradition of their local areas in choosing the shape of bottle most appropriate for their wine.

Many North and South American, South African, and Australasian wine producers select the bottle shape with which they wish to associate their wines. For instance, a producer who believes his wine is similar to Burgundy may choose to bottle his wine in Burgundy-style bottles.^{[citation needed]}

Other producers (both in and out of Europe) have chosen idiosyncratic bottle styles for marketing purposes. Pere-Anselme markets its Châteauneuf-du-Pape in bottles that appear half-melted. The Moselland company of Bernkastel-Kues in Germany has a Riesling with a bottle in the shape of a stylized cat. The British company Garçon Wines makes a flat wine bottle from recycled PET which is flat enough to fit through a letterbox and hence can be delivered by post.
