There are three appellations d’Origine Controlees in the wine region of Alsace. Alsace Grand Cru for white wines from classified vineyards, Alsace AOC for red, white, and rose wines, and Cremant d’Alsace AOC for sparkling wine, which is the only Alsace region that is allowed to label their wines based on varietal. A separate appellation, Alsace Grand Cru, was created in 1975, and as of 2009, there were 51 lieux-dits listed. Every wine that is labeled must be produced from Riesling, Pinot Gris, Muscat, or Gewürztraminer grapes. Crémant d'Alsace is an Appellation for sparkling wines. AOC status was granted on August 24, 1976. The wines are produced with traditional methods using Pinot Blanc grapes. The sparkling wines may also contain Riesling, Pinot Gris, Chardonnay, and Pinot Noir  grapes. Chardonnay cannot not be used in the two other Alsace appellations. Pinot Noir grapes in the region are used for Rose Cremant d'Alsace. Cremant d'Alsace is a huge part of the wine production in Alsace, with 18% of the vineyards in this region used for this purpose. Sparkling wine in Alsace goes back to 1900, when Julien Dopff applied the champagne method to his own wines that were produced in the Alsatian region.
