Domaine Ostertag is one of the most acclaimed producers in Alsace, in northeastern France. Owned and operated by Andre Ostertag, the domaine includes 120 parcels on 35 acres, which are all farmed biodynamically. The domaine was founded in 1966, when Andre’s father decided to go into winemaking. Ostertag makes single-vineyard Riesling and small-barrel-fermented Pinot Gris that Robert M. Parker Jr. calls “fascinating.” Also produced are Sylvander, Muscat and Gewürztraminer. Parker calls Ostertag’s wines “some of the most distinctively delicious and thought-provoking wines in Alsace.” Among the estate’s vineyards is the grand cru parcel Muenchberg, which was producing grapes for wine in the 12th century.
