Pascal Janvier did not expect to become a winegrower. He studied butchery, but at the age of thirty made a complete change of direction, enrolling at the viticultural school in Amboise and beginning to learn a craft he would eventually master. His quiet, deliberate approach to winemaking mirrors his personality: focused, unhurried, and deeply attentive to the particular character of each parcel. Today he is one of the most important figures in the revival of Jasnières, a tiny and once-obscure Loire appellation that produces some of France's most distinctive Chenin Blanc.
Backstory
Janvier began his winemaking career slowly and deliberately, building his holdings over time. He and his wife now farm 66 different parcels across a total of roughly nine hectares, managing everything themselves. His estate is based in Ruillé-sur-Loir, in the southern Sarthe, on the northern edge of the Loire Valley. He farms approximately eight hectares of Jasnières and four hectares in the Coteaux du Loir appellation, with vines averaging 35 to 40 years of age.
The Region
Jasnières is the most northerly and coldest appellation in the broader Loire zone, a fact that makes successful ripening a serious challenge most years. The appellation runs along south-facing slopes above the Loir River (distinct from the Loire), in the Sarthe department. The cool, demanding climate, combined with shallow soils rich in silex and clay over limestone bedrock, produces Chenin Blanc of a character quite different from the fuller, rounder expressions found in Vouvray or Savennières. Coteaux du Loir is the larger appellation surrounding Jasnières, where Pineau d'Aunis and other varieties are grown.
Vineyards and Farming
Janvier farms under lutte raisonnée principles, a thoughtful integrated approach that avoids systemic pesticides and synthetic treatments while adapting to the conditions of each season and parcel. The 66 plots vary in soil composition across the appellations, with the silex-dominant parcels producing the most mineral, smoky expressions of Chenin Blanc, while the clay-limestone plots deliver more fruit-forward character. All grapes are harvested by hand.
Winemaking
Fermentations take place with native yeasts in stainless steel, without malolactic conversion. Preserving the natural acidity and flinty mineral character of Jasnières is central to Janvier's approach. The wines are not manipulated to achieve a particular style and reflect the considerable variations between vintages in this marginal climate. The sparkling wine undergoes secondary fermentation using the traditional method, with 13 months of aging in production cellars before release.
The Wines
The core range includes the straight Jasnières (Chenin Blanc), the Cuvée du Silex (from the most flint-rich parcels, producing a smokier, more structured wine), Cuvée Sainte Narcisse, and two Coteaux du Loir cuvees: the Cuvée du Rosier and the red Cuvée Henri Quatre (Pineau d'Aunis with Cabernet Franc, Gamay, and Cot). A traditional-method sparkling Chenin Blanc is also produced. All are racy, mineral, and built for the table.
