Touraine-Oisly AOC

Touraine-Oisly occupies a plateau between the Loire and Cher rivers in the heart of Sologne, one of France's most distinctive natural regions. The appellation covers 10 communes: Oisly, Chémery, Choussy, Le-Controis-en-Sologne, Couddes, Méhers, Sassay, Soings-en-Sologne, Saint-Romain-sur-Cher, and Thenay. The elevated plateau position gives the area a sunnier, drier microclimate compared to much of the Loire Valley, a key advantage for ripening Sauvignon Blanc fully and consistently.

• Plateau setting between the Loire and Cher rivers reduces rainfall and increases sun exposure
• Semi-continental climate with oceanic influences shapes the growing season
• 10 communes fall within the appellation boundaries in Sologne
• Approximately 12 artisan winemakers farm the 80 hectares under vine

The soils of Touraine-Oisly reflect the Miocene epoch and vary meaningfully across the plateau. The western areas feature clay with limestone and flint silt, the central zones are sand-dominant, and the eastern portions shift to limestone with iron-rich sand. Throughout the appellation, the common thread is sandy-gravel soils on a clay base, which drain well, warm quickly, and were identified early on as ideal for Sauvignon Blanc. These soil variations contribute to the aromatic complexity the appellation is known for.

• Sandy-gravel soils on clay base dominate, with Miocene-epoch origins
• Western areas: clay with limestone and flint silt
• Central areas: sand-dominant profiles
• Eastern areas: limestone with iron-rich sand

The story of Sauvignon Blanc in Oisly stretches back to 1905, when a vine trellis was discovered on a local winegrower's lodge. Fabel Barbou is credited with reintroducing Sauvignon Blanc to the region at the start of the 20th century. Serious collective effort began in the late 1970s, when local winemakers selectively planted Sauvignon Blanc on the plateau's sandy soils. Decades of work paid off in 2011, when Touraine-Oisly was officially recognized as an AOC geographic denomination within Touraine AOC, joining four other Touraine sub-appellations.

• Sauvignon Blanc documented in the area as far back as 1905
• Fabel Barbou reintroduced Sauvignon Blanc at the beginning of the 20th century
• Selective planting on sandy soils began in earnest in the late 1970s
• AOC status granted in 2011 within the broader Touraine AOC framework

Touraine-Oisly produces exclusively dry white wines from 100% Sauvignon Blanc. The style is lively and expressive, with aromas of citrus, white flowers, and exotic fruits. A mandatory minimum of six months on fine lees before sale adds texture and aromatic depth that distinguishes these wines from lighter, earlier-released Loire Sauvignon Blancs. The appellation's commitment to environmental stewardship is total: every single estate carries certification in Agriculture Biologique, Terra-Vitis, or High Environmental Value (HVE).

• 100% Sauvignon Blanc; no blending permitted
• Dry, lively style with citrus, white flower, and exotic fruit character
• Minimum six months on fine lees before release
• All estates certified under Agriculture Biologique, Terra-Vitis, or HVE

Despite its small size, Touraine-Oisly has a well-defined community of committed growers. Domaine de la Chapelle, led by Thierry Gosseaume, and Domaine Octavie, run by Isabelle and Noë Rouballay, are two of the most recognized estates. Domaine Pré Baron (Jean-Luc Mardon), Domaine des Corbillières (Dominique Barbou), and the Saint-Romain-sur-Cher wine co-operative also contribute meaningfully to the appellation's output. With only around 12 artisan producers farming 80 hectares, the scale remains intimate and quality-focused.

• Domaine Octavie: Isabelle and Noë Rouballay
• Domaine Pré Baron: Jean-Luc Mardon
• Domaine des Corbillières: Dominique Barbou
• Saint-Romain-sur-Cher wine co-operative also active in the appellation
