Paul Langier Champagne Brut NV

The pressure inside a bottle of Champagne can be as high as 90 pounds per square inch (psi), which is about three times the pressure inside an average car tyre. This is because the carbon dioxide produced during the secondary fermentation is trapped inside the bottle, creating the wine's signature bubbles.

The traditional wire cage used to secure the cork in place is called a "muselet", it takes six half-twists to secure it properly.

The grapes, most commonly Chardonnay, Pinot noir and Pinot meunier, are used to make several base wines that are assembled together to make Champagne, English Sparkling wine and other classic cuvée wines.

Champagne blends can also include Arbane, Petit Meslier, Pinot Blanc and Pinot Gris. Other appelations have rules about which grapes can be included.
