The Champagne region enjoys very favorable conditions for vine cultivation, even with it’s contradicting northerly location. The rivers and forests help to regulate the humidity. The winters are relatively mild, the summer and fall rich in sunshine and the sun’s rays reflect back on the vines from the chalky soil, permitting maximum heat and light.
Champagne is planted on chalk. The Grand Crus generally are on the mid-slopes. The soil is a unique chalk a bit below the constantly fertilized topsoil. Thanks to this cradle, Champagne offers such lightness and refinement. The slopes facing South and Southeast attribute to the vines prosperity, protecting them from the Northerly winds and generously exposing them to the sun. The exceptionally intense light is reflected back by the soil expending the sun’s warmth.
As the map indicates, the vine growing region in Champagne primary consists in 4 zones. The Reims Mountain, the valley of the Marne river, the Côte des Blancs, the Aube. The vineyards strive on hills stretching 120 kilometres in length and from 300 metres to two kilometres in width.
La Montagne de Reims
The Reims Mountain zone is part of the Ile-de-France region. It consists of the versant meridian of the Vesle River Valley and expands to the Valley of the Marne River at the highs of Epernay. This is a vast plateau 20-25 kilometers in length and varies from 6 to 10 kilometers in width.
La Vallée de la Marne
The Marne Valley zones incorporates the vineyards situated between the towns of Tours-sur-Marne amd Dormans, extending to the city of Chateau-Thierry — in other words into the Aisne and Seine-et-Marne regions.
La Côte des blancs
The zone of Côte des Blancs is named after the white Chardonnay grapes grown there almost exclusively. The hills face east. The cliffs are perpendicular with the Reims Mountain. It is lower in elevation and stretches about 20 kilometers from the North to the South, between Epernay and the Marne River. It extends to Cote des Vertus in the Congy region and the Cote deSezanne hills. South of this zone, in the Aube region is the Cote des Bars zone, close to the villages of Bar-sur-Seine and Bar-sur-Aube.
This part is rather not known. In 2007 Alice Feiring scouted the Montgueux part of it.
