An invisible line slices through Alsace — north is Bas-Rhin, south is Haut-Rhin — and that subtle divide helps shape one of France’s most distinctive wine identities. Alsace is: - Long, narrow wine region between the Vosges Mountains and the Rhine River - One of the driest climates in France thanks to mountain rain shadow Appellations: - Alsace AOC — the foundation; varietal-labeled wines dominate - Alsace Grand Cru AOC — single-site wines from designated top vineyards - Labeling grape variety is standard practice, unlike most French regions Vineyards are planted along a fault line, which means there’s extreme soil diversity. - Granite → precision + lift - Limestone → structure - Marl → richness - Sandstone → aromatics Nerd Out - Alsace has one of the most geologically complex vineyard landscapes on earth, with dozens of soil types packed into a strip barely 75 miles / 120 km long. 🎯 Learn more at https://winefolly.com/deep-dive/alsace-wine-region/
