If each generation leaves its mark on a domaine, André Ostertag’s on Domaine Ostertag can’t be underestimated. In the 1980s, after training in Burgundy, he returned to the family domaine his father built in the 1960s with renewed zeal: he lowered yields considerably, brought biodynamic viticulture to his fourteen hectares of vineyards, and sought nuance in terroir rather than the typicity of a grape variety. His subtle use of oak barriques, sourced from the Vosges Mountains, served to bring greater depth on the palate for varieties from the Pinot family. His pioneering approach helped to define new expressions of Alsatian wine for the entire region.

André’s son Arthur has helmed the domaine since 2018. He continues to keep yields low, and in the cellar, pressing is slow and gentle so as not to tamper with the grapes' amers (subtle bitter notes), which preserves longevity and dimension in the finished wines. He favors long élevages, all with the goal of making wines that “create thirst,” not quench it; wines that are savory and complex. Arthur has also supplemented the domaine’s historical cuvées with original bottlings of his own, highlighting new lieux-dits and experimenting with techniques such as skin maceration that show off his individuality as a vigneron.
