The 51 Grands Crus of Alsace, located on the hills of the sub-Vosges on exceptional land and sometimes on impressive slopes, are all privileged terroirs where the geology, climate and exposure form an exceptional combination. The AOC Grand Cru has very strict delimitation and regulations to ensure the quality and rarity of these wines. They become unique, fine and complex wines, most often suitable for ageing. The rigorous work of the men and women allows the wines to fully express their terroir through their aromas and structure.

The grape varieties allowed are the so-called "noble" Alsatian varieties: Riesling, Muscat, Pinot Gris and Gewurztraminer. Only the Grand Cru Zotzenberg is allowed to grow Sylvaner.
