At the geological level, the vines of the Saumur Champigny wine region are planted on soils mainly composed of tufa chalk and clay-sandy sediments from the Turonian era. Historically, the Saumur-Champigny vineyard dates back a thousand years. The vines were planted in the second half of the 11th century by the monks of Saint-Florent on the hillside which overlooks the Loire between Saumur and Montsoreau. If at that time it was white wine that dominated, since the 17th century and the introduction of Cabernet Franc, Saumur Champigny is now a country of red wines only.
