Coteaux du Loir AOC

Coteaux du Loir has one of the Loire Valley's most storied histories. Cistercian monks developed the vineyards during the Middle Ages, and the wines attracted royal and literary attention for centuries. King Henry IV celebrated them, they were mapped under Louis XIV, and Renaissance writers Rabelais and Ronsard both enjoyed wines from this valley. Phylloxera arrived in 1876, devastating the vineyards and sending production into a long decline from which the appellation is still recovering. A qualitative revival began in the 1970s and continues today, with a growing number of producers embracing organic and biodynamic farming.

Coteaux du Loir sits within the broader Touraine appellation of the Loire Valley, spanning 22 communes, 16 in the Sarthe department and 6 in Indre-et-Loire. The appellation follows the Loir River, a tributary of the Loire, not the Loire itself. It ranks among the most northerly appellations in the Loire Valley, giving it a cooler character than central Touraine. The Bercé Forest to the north provides protection from cold winds, and the Atlantic Ocean moderates temperatures through the region's temperate oceanic climate. Summers are warm with cool nights, winters are mild, and spring frosts remain a real risk.

The hillside slopes of Coteaux du Loir are defined by Turonian chalk, locally known as tuffeau, which breaks down into flint clays across much of the appellation. Some areas also feature clay-to-flint soils and alluvial terraces. The tuffeau is the same material found throughout Touraine and is prized for its excellent drainage and heat retention. It imparts a distinctive mineral, flinty quality to the Chenin Blanc whites, contributing to their considerable aging potential.

• Primary soils are Turonian chalk (tuffeau) broken down into flint clays on hillside slopes
• Some zones feature clay-to-flint soils and alluvial terraces
• Tuffeau provides excellent drainage and heat retention
• Mineral, flinty soil character translates directly into the Chenin Blanc whites

Three wine styles are produced under the Coteaux du Loir AOC. White wines, accounting for 35-40% of production, are made from 100% Chenin Blanc and range from crisp, mineral-driven dry styles to semi-sweet and fully sweet botrytized moelleux. Red wines make up 45-50% of production and require a minimum of 65% Pineau d'Aunis, blended with Cabernet Franc, Côt (Malbec), and Gamay. These reds are light-bodied, spicy, and peppery with moderate tannins. Rosés, contributing 14-20% of production, are light-bodied and fruity, built primarily from Pineau d'Aunis alongside the other permitted varieties. Pineau d'Aunis itself is a historic grape cultivated in this valley for over 1,000 years.
