Champagne
Aÿ is most famous as a centre of the production of Champagne. Aÿ's vineyards are located in the Vallée de la Marne subregion of Champagne, and are classified as Grand Cru (100%) in the Champagne vineyard classification. The vineyards, harvest huts, presses, and cellars in the region were inscribed on the UNESCO World Heritage List in 2015 as part of the Champagne hillsides, houses and cellars site, because of the region's testimony to the development of champagne. Many prestigious Champagne houses own vineyards in the immediate vicinity, and several producers are located in Aÿ, including Ayala and Bollinger.
