The Alsace Grand Cru designation represents the pinnacle of quality in the Alsace wine region of France. Established in 1983, the Grand Cru status is reserved for wines produced under strict regulations from designated vineyards that highlight the unique terroirs of Alsace. These vineyards are situated in specific parcels that are recognized for their superior climatic and geological conditions, which contribute to the distinctive expressions of the wines.

Alsace Grand Cru wines are predominantly white and made from four principal grape varieties: Riesling, Gewurztraminer, Pinot Gris, and Muscat. Each variety brings its unique flavor profile to the wines, from the floral and aromatic intensity of Gewurztraminer to the crisp, mineral complexity of Riesling. The wines are known for their precision, depth, and ability to age gracefully, developing rich, nuanced flavors over time.

The Alsace Grand Cru system currently includes 51 officially classified vineyard sites, each with its own distinct characteristics and regulations regarding viticulture and winemaking practices. These sites are often marked by steep slopes that provide optimal exposure to sunlight, enhancing the ripening of the grapes. The soils vary widely across the Grand Cru areas, from volcanic and sandstone to limestone and marl, each adding a unique element to the wine's profile.

Alsace Grand Cru wines are celebrated for their quality and diversity, offering a wide range of styles from dry and intensely mineral to sweet and sumptuously fruity. They reflect the rich cultural heritage of Alsace, a region influenced by both French and German winemaking traditions, and are highly sought after by connoisseurs and collectors around the world.
