Semi-sparkling wine
Fully sparkling wines, such as champagne, are generally sold with 5 to 6 standard atmospheres (73 to 88 psi; 510 to 610 kPa) of pressure in the bottle. This is more than twice the pressure found in an automobile tire. European Union regulations define a sparkling wine as any wine with an excess of 3 atmospheres in pressure. These include German sekt, Spanish espumoso, Italian spumante and French crémant or mousseux wines. Semi-sparkling wines are defined as those with between 1 and 2.5 atmospheres of pressures and include German spritzig, Italian frizzante and French pétillant wines. The amount of pressure in the wine is determined by the amount of sugar added during the tirage stage at the beginning of the secondary fermentation with more sugar producing an increased amount of carbon dioxide gas and thus pressure in the wine.
