Jean-Pierre and Sophie Rietsch are winemakers based in Mittelbergheim, a picturesque village in Alsace, France, where their family has been involved in viticulture and related trades since the 17th century. They manage Domaine Rietsch, a 12-hectare estate fully converted to organic farming in 2008, emphasizing natural winemaking and respect for the terroir. Their approach prioritizes minimal intervention, using indigenous yeasts, long elevage on fine lees (sometimes 5–24 months), and minimal or no sulfur additions, resulting in vibrant, complex wines with strong aging potential. They cultivate classic Alsatian grape varieties like Riesling, Gewurztraminer, Pinot Gris, and Pinot Noir, alongside rarer ones like Klevener de Heiligenstein, often employing unique techniques such as extended maceration for skin-contact wines (e.g., "Quand le Chat" and "Demoiselle") and solera aging. Their wines, known for elegance, minerality, and high drinkability, come from notable terroirs like the Grand Cru Zotzenberg, Stein, and Brandluft.

The domaine, founded in the 1970s by Jean-Pierre’s parents, Pierre and Doris Rietsch, transitioned from mixed farming (including tobacco) to a dedicated winery. Jean-Pierre took over in 1987, with Sophie joining him in the early 2000s. They work with La Main Verte, an organization supporting the integration of mentally disabled individuals through vineyard tasks like pruning and trellising. The family-oriented operation, assisted by Pierre-Etienne Grieshaber and occasionally Pierre Rietsch, uses traditional foudres in their cellar, some in place for three generations. Their labels, designed by a friend named Andréa since the 1980s, reflect the wines’ charm and individuality.

Jean-Pierre is recognized for his innovative spirit, experimenting with long macerations and skin-contact wines, setting him apart in Alsace alongside peers like Patrick Meyer and Jean-Pierre Frick. Their wines, including Crémant d’Alsace, whites, reds, and rosés, are celebrated for their authenticity, balance, and expression of Alsace’s diverse terroirs. The domaine is a staple at natural wine fairs across Europe, from France to Italy and Spain. For more details, visit their website at alsace-rietsch.eu
