Diabas – the influence of volcanic rock on Riesling
But what makes the Saarburger Rausch so special? This question has lingered in my mind for years, especially when savoring Zilliken’s wines. So, it was time to uncover the mystery. As befits a charming and humble winemaker like Dorothee Zilliken, she promptly replied, “Max, look around. It’s all about the vineyard. Its exposition, combined with the unique soil structure shaped by Diabas rock.” Dorothee would never overemphasize her own talent or that of her father, Hanno, as winemakers, though undoubtedly a crucial factor in the finesse of Zilliken’s wines. The truth likely lies somewhere in the middle. But now, back to the vineyard.
The soil, characterized by graywacke, fine-bladed Devonian slate, and reddish fine earth, is pierced by volcanic basalt, also known as Diabas. This volcanic influence gives the Riesling a very unique spicy character rooted in the depth of the soil, up to 10 meters below the surface. This exceptional composition is extremely rare and extends along the Saar only in the Konzer Tälchen over the vineyards of Krettnacher Altenberg and Krettnacher Euchariusberg.
The name “Steinrausch” or “Rusche,” a term for debris from the old dialect, hints at the rugged beauty of this place. The current vineyard name RAUSCH derives from this term.
