Avenue de Champagne, Épernay

The Avenue de Champagne in Épernay is the most commercially prestigious road in France's Grand Est and arguably in all of French wine culture, a 2-kilometre boulevard flanked by the headquarters and cellars of the world's most famous Champagne houses: Moët & Chandon, Perrier-Jouët, Pol Roger, Castellane, and de Venoge, among others. Beneath the avenue, 110 km of chalk cellars hold an estimated 200 million bottles of Champagne in various stages of ageing, making the deposit one of the largest wine collections in existence. The above-ground architecture ranges from the neoclassical Moët & Chandon mansion (established 1743) to the Victorian Perrier-Jouët villa with its Art Nouveau floral facade, a listed historic monument. Most major houses offer guided cellar tours with tasting, ranging from a 1-hour introduction (€15–€30) to multi-cuvée premium experiences (€50–€70); booking ahead is essential at Moët & Chandon and Perrier-Jouët. The avenue itself is free to walk and is lined with impressive mansion facades and ornamental gardens. At the western end, the Castellane tower (45 metres) can be climbed for a view over the avenue and the Marne river valley beyond. Épernay is 26 minutes by train from Reims, and the avenue begins a 5-minute walk from the railway station. The Fête du Champagne in late May transforms the avenue into an open celebration with walk-in tastings from multiple houses.
