Terroir of Alsace Grand Cru
Alsace's Grand Cru terroir is a patchwork of various soils, like granite, schist, limestone, marl, sandstone, clay, and volcanic elements. Each vineyard has its own unique geological character, adding distinct styles to the wines. Vines are carefully planted on steep, south or east-facing slopes at heights between 200 and 450 meters, where cool nights help keep acidity. The well-drained, rocky soils absorb daytime heat and release it after sunset, aiding grape ripening.
The region has a continental climate, protected from Atlantic rain by the Vosges Mountains, leading to low annual rainfall of 500–600 mm and plenty of sunshine, about 1,800–2,000 hours. Warm, dry summers allow full ripeness, while cold winters let the vines rest. Spring frost can be tricky. Each vineyard has a unique character due to different slopes, altitudes, and closeness to the Rhine.
