Ernst Loosen took over a family estate in 1988 that most would have considered an embarrassment of riches. Ungrafted vines averaging over a century in age, sitting in three of the Mosel's great Grosse Lagen, Wehlener Sonnenuhr, Urziger Wurzgarten, and Erdener Treppchen, with nobody paying them proper attention. What followed was a methodical reset: smaller crops, gentler cellaring, and a commitment to letting each site speak for itself. Thirty-five vintages later, the Grosses Gewachs wines from these three sites are some of the Mosel's best.

The approach in the cellar is consistent across all three GGs. Ungrafted vines, ambient fermentation, twelve months in large oak foudres. Nothing about the winemaking is designed to impose. The point is to clearly hold each vineyard's signature. And the signatures are distinct. Sonnenuhr, with its pure Devonian-blue slate and almost no topsoil, leans toward elegance and fine-boned precision. Wurzgarten sits on rare red volcanic sandstone, unique in the Mosel, and the wines carry that into a more muscular, spiced register. Treppchen, in oxidised red slate just above the Pralat, tends toward structure and a racy, mineral tension that rewards patience.

The 2024 vintage in the Mosel rewarded those who knew their sites, and the GGs show it. Cool conditions and a long ripening window held acidity beautifully, and Erni is unambiguous about the result: "An absolutely gorgeous vintage. We all have been tasting and thought, wow." The three sites read clearly and distinctly, which is what you want from wines at this level.
