The Montagne de Reims is the most northerly and easterly region of Champagne. Vineyards here are planted mostly to Pinot Noir which produces some of the most precise and intensely structured wines in Champagne. Many tête de cuvée wines from major Champagne houses originate from Montagne de Reims.
Vallée de la Marne has an abundance of southern facing slopes producing the ripest wines with full aroma. The grapes, mostly Pinot Meunier, are known for their fruity and unctuous flavors.
The Côte des Blancs produces mostly Chardonnay wines that are elegant and racy. The eastern-facing slope that owes its name to the color of the grape planted here grows in chalk-based soils which produce wine with higher acidity. Champagnes in this area include the term “blanc de blancs”.
The Côte de Sézanne is the most rapidly developing region in Champagne. Producing mostly Chardonnay, these aromatic wines have less acidity than Côte des Blancs due to soils with both chalk and marl.
The Aube (aka Côte des Bar) is the largest region in Champagne and accounts for 65% of the area planted in Champagne. The Aube belongs to a separate geological region from the rest of Champagne and produces mostly Pinot Noir in marl soils resulting in aromatic wines with less acidity.
