Alsace and Champagne 3D Wine Map: Grands Crus on Real Terrain

The Vosges rain shadow, 51 Grands Crus, and Champagne’s chalk slopes in full 3D terrain.

This interactive 3D wine map shows Alsace and Champagne on real terrain: all 51 Alsace Grands Crus on the slopes of the Vosges, the Alsace and Crémant d’Alsace appellations, Champagne, Coteaux Champenois and Rosé des Riceys, plus the Lorraine appellations of Côtes de Toul and Moselle, drawn in 3D by SommGeo. Tilt and fly over the vineyards, check elevation and slope, and run the daylight and shadow animation to see how each site faces the sun. Click any appellation and a profile opens with its grapes and character. The interactive map is part of SommGeo membership, which starts with a free 15-day trial.

• Appellations on the map: 58, including all 51 Alsace Grands Crus
• Rain shadow: The Vosges block westerly rain, making Colmar one of the driest towns in France
• Grand Cru grapes: Riesling, Gewurztraminer, Pinot Gris and Muscat, with Sylvaner also allowed in Zotzenberg
• Champagne soils: Chalk under the Montagne de Reims and the Côte des Blancs
• Champagne grapes: Chardonnay, Pinot Noir and Meunier
• 3D tools: Tilt and rotate the terrain, elevation and slope readouts, daylight and shadow animation and a weather overlay

This 3D Fast Map covers two of northeastern France’s defining wine regions, and the terrain tells you immediately why they produce such different wines despite sitting relatively close together. Alsace is sheltered east of the Vosges Mountains, one of the driest vineyard corridors in France, where south- and southeast-facing slopes on granite, limestone, and volcanic soils produce aromatic, single-variety whites of striking terroir expression. Champagne, to the west, sits on a broad chalk basin where the gentle slopes of the Montagne de Reims, Vallée de la Marne, and Côte des Blancs create the conditions for the world’s reference point in sparkling wine. The 3D terrain makes both stories visible: the Vosges wall that creates Alsace’s microclimate, and the rolling chalk hills that define Champagne.

Key Regions in Focus

Alsace and the Vosges Rain Shadow

Alsace’s entire viticultural identity depends on the Vosges Mountains. The range runs north to south along the region’s western edge, rising to roughly 1,000 to 1,400 meters (3,280 to 4,593 ft), and intercepts moisture-laden Atlantic weather systems before they reach the vineyards. The result is one of the driest growing seasons in France: Colmar, in the heart of the region, averages around 550 millimeters (21.7 inches) of annual rainfall. Vineyards line the east-facing slopes of the Vosges foothills between roughly 200 and 400 meters (656 and 1,312 ft), on a patchwork of granite, gneiss, limestone, sandstone, and volcanic soils that changes dramatically over short distances. The 51 Grands Crus are defined by this geological diversity: Schlossberg (granite), Rangen (volcanic), Brand (granite), Hengst (marl/limestone) each produce distinct expressions of Riesling, Gewurztraminer, Pinot Gris, and Muscat. The 3D terrain makes the Vosges wall and its rain shadow effect immediately visible.

Champagne

West of the Vosges, the terrain opens into the broad Paris Basin, and Champagne sits on its eastern rim where belemnite chalk comes close to the surface. The region’s geography divides into distinct sub-zones visible in the 3D map.The Montagne de Reims, a broad forested plateau south of Reims, has Pinot Noir-dominant Grand Cru villages on slopes that wrap around the horseshoe-shaped massif. Verzenay and Mailly sit on north-facing slopes, while Ambonnay and Bouzy face south to southeast, and the differing exposures produce markedly different styles of Pinot Noir. The Vallée de la Marne follows the river westward, with Pinot Meunier dominating on the cooler, clay-rich north-facing bank. The Côte des Blancs, running south from Épernay, is the Chardonnay heartland: a continuous east-facing chalk escarpment with Grand Cru villages (Cramant, Avize, Le Mesnil-sur-Oger) producing the most mineral, age-worthy blanc de blancs base wines. Further south, the Côte des Bar (Aube) sits on Kimmeridgian marl, the same formation found in Chablis, and has become increasingly important for Pinot Noir. The terrain here is gentler than Alsace, but the subtle slope angles and exposures are what separate Grand Cru from village-level sites.
