Domaine Ostertag produces wines from Alsace, the northeastern French region celebrated for aromatic white varieties and late-harvest expressions. The domaine works primarily with Riesling and Gewürztraminer, grapes that thrive in Alsace's continental climate and mineral-rich soils. Le Berceau, a Riesling, and Muenchberg Riesling represent the domaine's dry wine portfolio, while Fronholz Selection de Grains Nobles de Gewürztraminer showcases the region's tradition of botrytized, sweet wines of considerable complexity. These wines have been assessed by major critics including Decanter, Wine Spectator, Wine Enthusiast, Wine Advocate, and Falstaff, reflecting their standing within the international wine press.
