Around since 1851, Bouvet Ladubay in Saumur produces 20 different types of sparkling wine. Try them all during a visit to the award-winning winery—just don’t expect a typical tasting experience. Here, guests can learn about the winemaking process while riding vintage bicycles through Bouvet Ladubay’s three miles of ancient cellars, located beneath the ruins of the 11th-century Abbey of St-Florent de Saumur. The tour, which includes several tastings, takes about 90 minutes.
