The highest point of the Montagne de Reims (Reims Mountain) is Mount Sinai (286m). This mountain, 70 million years old, represents a real geological “millefeuille”: chalk, sand, clay, and limestone which give the Champagne wine its distinctive aromas.

It owes its richness to its fragmentation, each village constituting a “cru”.
