The Cordeliers Cloister site is famous for its underground tunnels that were excavated for the stone used to build Saint-émilion and some parts of Bordeaux. They are 3km long and run beneath the Saint-émilion citadel and some of its major vineyards. They are 20m underground, have a constant temperature of 12° throughout the year and are totally dark, making them perfect for ageing the wines we have been making since 1892 using traditional methods. You can visit our cellars and underground tunnels where you can discover the underside of the medieval citadel of Saint-émilion and learn about our own sparkling wine making methods.
