Fodor's Expert Review Taittinger

Cavernous chalk cellars, first used by monks for wine storage, house 15 million bottles and partly occupy the crypt of the 13th-century abbey that used to stand on this spot. Inside, you can also see a model of the abbey and its elegant church, both demolished during the French Revolution. The 1½-hour guided tour starts with a short film, then continues with a walk through the 4th-century Gallo-Roman cellars and 13th-century vaults of St-Nicaise Abbey, and ends in a huge cave where locals were once sheltered from the Germans. The visit is topped off with a tasting. There are seven categories of tastings; the top-end choice, L'Instant de Grâce (€77), offers three Champagnes, including Taittinger's finest cuvée, the Comtes de Champagne Blanc de Blancs. Tours in English happen just about every hour—check online for times. No appointment is necessary. Due to major restorations Taittinger's cellars will be closed until 2025.
