The correct answer is based on the current classification system for Alsace Grand Cru vineyards, which recognizes a total of 51 distinct Grand Cru sites. This classification marks them as superior quality vineyards that are approved for producing top-tier wines, primarily from specific grape varieties such as Riesling, Gewürztraminer, Pinot Gris, and Muscat. Each of these vineyards has been rigorously assessed for their terroir and the potential to produce exceptional wines, which are characterized by their unique microclimates and soil types.
