These sites in Champagne, a region in north-east France, are recognised for producing the drink that bears the area's name.

The three components - the supply basin formed by the historic hillsides, the production sites with their underground cellars, and the Champagne Houses, which are sales and distribution centres - illustrate the entire production process.

Unesco said the sites bear "clear testimony to the development of a very specialised artisan activity that has become an agro-industrial enterprise". The sparkling wine of champagne is produced via secondary fermentation in the bottle. This makes champagne "bubbly" owing to the containment of carbon dioxide.

Burgundy, another wine-making region in France, was also inscribed on the Unesco World Heritage List. Vineyards there produce some of the world's finest red wines.
