Mercier

Mercier is near Moët et Chandon, and you can visit them both on the same day. Mercier conducts tours in English of its 18km (11 miles) of tunnels from laser-guided trains—reached by an elevator that descends past rudimentary champagne-themed dioramas. The caves contain one of the world’s largest wooden barrels, with a capacity of more than 200,000 bottles. The best tour to choose here is the 2 hr. Exploring the Vineyard tour, which does what it says on the label: takes you through the cellar and into the vineyards. Reservations recommended.
