A very long time ago the North of France housed an inner sea. Evidence of this sea and its seabed can be found in the soil of most of this area, where remains of shellfish and fossils are easily tracked. A high concentration of chalk is the result and forms the character of the region we now call Champagne. Because of the chalk, the soil is very permeable to water, so rainwater is easily dissipated and warmth of the sun during the day is released at night. A calcareous subsoil (often chalk-based), absorbs heat and facilitates vine drainage, promoting the balance of the grapes and creating vast underground caves, perfect for ripening wines.
Champagne, however, is not Burgundy. Its climate is not as tolerant, nor is its soil as diverse. Campagne’s chalky soils and unique climate create the perfect conditions for crafting its renowned sparkling wine. Champagne's excellence is determined by the combination of grape excellence and winemaker expertise.
Champagne is a white wine. However, the wines if made from mostly blue grapes: pinot noir en pinot meunier. Chardonnay is also used. A Champagne made from 100% Chardonnay grapes is called Blanc de Blancs, a Champagne made from 100% blue grapes is called Blanc de Noirs. The latter is quite rare.
Some of the best Champagnes come from domaines like Selosse, Krug, Bollinger, Veuve Clicquot, Armand de Brignac, Salon, Roederer, Moet et Chandon
