The Champagne province is located near the northern limits of the wine world along the 49th parallel. The high altitude and mean annual temperature of 10 °C (50 °F) creates a difficult environment for wine grapes to fully ripen. Ripening is aided by the presence of forests which helps to stabilize temperatures and maintain moisture in the soil. The cool temperatures serve to produce high levels of acidity in the resulting grape which is ideal for sparkling wine.

Ancient oceans left behind chalk subsoil deposits when they receded 70 million years ago. Earthquakes that rocked the region over 10 million years ago pushed the marine sediments of belemnite fossils up to the surface to create the belemnite chalk terrain. The belemnite in the soil allows it to absorb heat from the sun and gradually release it during the night as well as providing good drainage. This soil contributes to the lightness and finesse that is characteristic of Champagne wine.
