Wehlener Sonnenuhr ('sundial'), positioned as one of Mosel's most storied and celebrated vineyard sites, offers its south-facing slope and distinctive slate soils producing Rieslings of exceptional mineral precision and aromatic depth. The vineyard's historic 'sundial' orientation maximises afternoon sun exposure, warming the slate bedrock and accelerating grape ripeness whilst maintaining the region's critical signature acidity. Dr. Loosen holds prime parcels here, worked by hand across generations of careful stewardship. The estate employs sustainable practices respecting the fragile slate environment and vintage expressions. The 2024 vintage saw moderate Mosel conditions, allowing the terroir's inherent flinty character.

Grapes are hand-selected and harvested at physiological maturity, with careful sorting to maintain and ensure quality standards for each batch. Following gentle crushing and slow pneumatic pressing to preserve aromatic freshness, juice ferments in stainless steel using wild yeasts, a methodical process extending many months through multiple seasons. The young wine rests on fine lees through winter, developing subtle aromatic complexity and textural elegance from extended contact. Spring racking removes coarse sediment whilst preserving fine lees character that enhances mineral expression. Minimal sulphiting and unfiltered bottling retain the wine's delicate mineral character and natural aromatics.
