Loire Valley Wine Map: All 53 AOPs in 3D, Interactive

Sancerre, Pouilly-Fumé, Vouvray, Chinon, Muscadet, and the full length of France’s longest wine river.

This interactive 3D Loire Valley wine map shows all 53 AOPs along France’s longest river on real terrain, from Muscadet at the Atlantic through Savennières, the Coteaux du Layon, Saumur-Champigny, Chinon, Bourgueil and Vouvray to Sancerre, Pouilly-Fumé and the upper Loire in the Auvergne, drawn in 3D by SommGeo. Fly between areas with the bookmarks, check elevation and slope, run the daylight animation and click any appellation for its grapes and rules. The interactive map is part of SommGeo membership, which starts with a free 15-day trial.

• Appellations on the map: All 53 AOPs, every boundary clickable, from the Pays Nantais to the Auvergne
• The river: About 1,000 kilometers (620 miles) long, France’s longest, with vineyards along most of it from Nantes to the Central Vineyards
• Three whites: Melon de Bourgogne in the west, Chenin Blanc through Anjou, Saumur and Touraine, Sauvignon Blanc in the east
• Reds: Cabernet Franc in Chinon, Bourgueil, Saint-Nicolas-de-Bourgueil and Saumur-Champigny; Gamay and Pinot Noir upstream
• Soils: Gneiss and granite in the Pays Nantais, tuffeau limestone in Anjou and Touraine, Kimmeridgian limestone and silex around Sancerre
• 3D tools: Tilt and rotate the terrain, bookmarks to fly between areas, elevation profile readouts, daylight and shadow animation and a weather overlay

The Loire is France’s longest river at roughly 1,000 kilometers (620 miles), and its wine regions stretch nearly the entire navigable length, from the Atlantic coast near Nantes to the Central Vineyards around Sancerre and Pouilly-Fumé far inland. What makes the Loire compelling in 3D is the way climate shifts from west to east as Atlantic influence fades: maritime at the mouth, increasingly continental toward the center of the country. The geology changes too, from the gneiss and granite of the Pays Nantais through the tuffeau limestone of Anjou and Touraine to the Kimmeridgian limestone and silex of the Central Vineyards. Three primary white grapes track these shifts: Melon de Bourgogne in the west, Chenin Blanc through the middle, and Sauvignon Blanc in the east.

Key Regions in Focus

Pays Nantais and Anjou-Saumur

At the western end, the Pays Nantais sits closest to the Atlantic, where Melon de Bourgogne produces Muscadet on gneiss, granite, and gabbro soils. The cru communaux system (Clisson, Gorges, Le Pallet, and others) distinguishes specific terroirs within the larger Muscadet Sèvre et Maine appellation, each with minimum lees-aging requirements. Moving upstream, Anjou-Saumur is Chenin Blanc territory in all its forms: the dry, sweet, and sparkling wines of Savennières, Coteaux du Layon, Quarts de Chaume, Bonnezeaux, and Saumur Brut all come from Chenin grown on schist and tuffeau limestone. The tuffeau caves carved into the hillsides along the Loire provide natural cellaring conditions for the region’s traditional-method sparkling wines. Cabernet Franc produces the reds of Saumur-Champigny.

Touraine

Touraine straddles the middle Loire around Tours, where the Cher, Indre, and Vienne tributaries join the main river. Vouvray and Montlouis-sur-Loire face each other across the Loire, both producing Chenin Blanc in dry, demi-sec, moelleux, and sparkling styles, but from different bank exposures and slightly different tuffeau limestone profiles. South of the Loire, Chinon and Bourgueil (including Saint-Nicolas-de-Bourgueil) are the reference points for Loire Cabernet Franc: medium-bodied, aromatic reds with the fresh, herbal character that distinguishes Loire Cab Franc from warmer-climate expressions. The terrain here is gently undulating, and the tributary valleys create sheltered mesoclimates visible in the 3D map.

Central Vineyards

The Central Vineyards sit far inland around the upper Loire, where the climate is decisively continental and Sauvignon Blanc is the dominant grape. Sancerre occupies a series of hills on the west bank of the Loire, with three principal soil types: terres blanches (Kimmeridgian marl), caillottes (Oxfordian limestone, pebbly and well-drained), and silex (clay laced with flint). The soil profile shifts broadly from west to east across the appellation, and most producers blend across soil types rather than bottling them separately. Pouilly-Fumé faces Sancerre across the river on the east bank, also on Kimmeridgian limestone with significant silex deposits. The ‘fumé’ in the name refers either to the flinty, smoky quality of the wine or to the grey bloom on ripe Sauvignon Blanc grapes, depending on which local you ask. Menetou-Salon, Quincy, and Reuilly round out the Central Vineyards with similar varieties in slightly different settings.
