Winemaker Notes
In 2018 Stéphane Riffault made the decision to release a village-level Sancerre after additional planting that he has undertaken over the last decade on limestone terroirs. It also includes some fruit from Les Boucauds and Les Chasseignes

Robert Parker's Wine Advocate
A lively, incisive bouquet of lemon, spring flowers, acacia and pear preface the 2022 Mosaïque Calcaire, a moderately weighted, perfectly balanced and textural Sancerre with a fleshy core of fruit, bright acids and a long, mouthwatering, penetrating finish. This is a fruity rendition of calcareous soils.

The new name for Riffault's Sancerre Blanc, 2022 Mosaïque Calcaire, is the house's main wine, combing up to 20 parcels. It's a supple, almost succulent style with ripe fruit - melon, pear and pineapple. It has a charming tenderness and holds the mouth with comforting reassurance. It remains light on its feet, like a cloud of Sancerre floating. It's ripe, but the alcohol remains moderate, and there's gentle acidity there.
Capable of a vast array of styles, Sauvignon Blanc is a crisp, refreshing variety that equally reflects both terroir and varietal character. Though it can vary depending on where it is grown, a couple of commonalities always exist—namely, zesty acidity and intense aromatics. This variety is of French provenance. Somm Secret—Along with Cabernet Franc, Sauvignon Blanc is a proud parent of Cabernet Sauvignon. That green bell pepper aroma that all three varieties share is no coincidence—it comes from a high concentration of pyrazines (herbaceous aromatic compounds) inherent to each member of the family.
Marked by its charming hilltop village in the easternmost territory of the Loire, Sancerre is famous for its racy, vivacious, citrus-dominant Sauvignon blanc. Its enormous popularity in 1970s French bistros led to its success as the go-to restaurant white around the globe in the 1980s.
While the region claims a continental climate, noted for short, hot summers and long, cold winters, variations in topography—rolling hills and steep slopes from about 600 to 1,300 feet in elevation—with great soil variations, contribute the variations in character in Sancerre Sauvignon blancs.
In the western part of the appellation, clay and limestone soils with Kimmeridgean marne, especially in Chavignol, produce powerful wines. Moving closer to the actual town of Sancerre, soils are gravel and limestone, producing especially delicate wines. Flint (silex) soils close to the village produce particularly perfumed and age-worthy wines.
About ten percent of the wines claiming the Sancerre appellation name are fresh and light red wines made from Pinot noir and to a lesser extent, rosés. While not typically exported in large amounts, they are well-made and attract a loyal French following.
