Sancerre is a French appellation located in Loire Valley (Cher department) that is mainly known for the production of dry white wines from Sauvignon Blanc grapes. The wines are praised for mineral notes and freshness, while three different soils—terres blanches, les caillottes, and silex (flint)—may influence their final character.
Those produced on terres blanches soils are often more aromatic and full-bodied, while caillottes (marl and gravel) tend to create lighter and fruitier expressions. Silex terroir gives Sancerre wine typical mineral and gunflint notes. The most common aromas found in Sancerre are reminiscent of white flowers, citrus, white fruit, and herbal notes.
