2025 Peter Lauer, Ayler Kupp Stirn Fass 15, Mosel - Magnum

Florian Lauer’s approach to the Ayler Kupp—specifically the Stirn parcel—centers on rigorous parcel-based viticulture and a commitment to non-interventionist cellar practices, including spontaneous fermentation and extended aging in neutral wooden vessels. Sourced from the summit of the Ayler Kupp, these Riesling vines are deeply rooted in shallow, stony slate, a site-specific reality that defines the wine’s lean, mineral-driven architecture. The 2025 growing season, characterized by early vine development and a compact, high-intensity harvest, provided the necessary conditions to achieve physiological ripeness while maintaining the high, bracing acidity essential to this Fass 15 expression. The resulting wine is defined by its pronounced structural tension, fine-grained texture, and a persistent, saline linearity that highlights the site’s steep-slope terroir.
