Wehlener Sonnenuhr

Wehlener Sonnenuhr sits in the heart of the Middle Mosel, perched above the village of Wehlen on slopes that rise from 110 to 320 meters above sea level. The aspect is predominantly south to south-southwest, ensuring maximum sun exposure throughout the growing season. The soils consist almost entirely of blue and grey Devonian slate, medium in depth and pure in composition. Slate is the defining element here: it absorbs heat during the day and radiates it back to the vines at night, moderating the cool Mosel climate and allowing Riesling to ripen fully even in marginal vintages. The vineyard also benefits from heat reflected off the surface of the Mosel river below, creating a microclimate that can capture up to ten times more sunlight than flat agricultural land. This combination of reflected light, radiated heat, and free-draining slate soils produces the conditions for Riesling of exceptional quality and longevity.

• Devonian slate soils provide heat retention, drainage, and a signature mineral character in the wines
• South to south-southwest aspect captures maximum sunlight in this cool-climate region
• Heat reflected from the Mosel river amplifies the microclimate's warmth
• Elevation range of 110 to 320 meters creates variation in ripening across the site

The Sonnenuhr name derives from the large sundial erected in the vineyard in 1842 by Jodocus Prüm, originally installed to help workers in the steep, isolated parcels track the time of day. Before this landmark became synonymous with the site, the vineyard was known as Lammerterlay. The name Sonnenuhr, meaning sundial, was officially approved as a registered vineyard designation in August 1913, at which time the delimited area measured just 8 hectares. Following the German wine law reforms of 1971, the site was expanded significantly, reaching its current extent of approximately 40 hectares in 1954 before that law reshaped the broader landscape of German vineyard registration. The vineyard's reputation stretches back much further: it was recognized as exceptional since Roman times, and in 1868 it received top marks in the Prussian royal vineyard classification, placing it among the elite sites of the Mosel. Today, its prime parcels hold VDP.GROSSE LAGE status, the highest classification in the VDP system for individual vineyards.

Riesling accounts for over 99% of plantings in Wehlener Sonnenuhr, and the wines produced here rank among the most elegant expressions of the variety anywhere in the world. The style is defined by delicate, precise acidity, vibrant mineral freshness, and stone fruit character dominated by peach and apricot. These are not heavy or opulent wines; they carry their concentration with lightness and tension. Producers work across the full Prädikat range, from dry Grosses Gewächs bottlings to luscious Auslese, Beerenauslese, and Trockenbeerenauslese at higher Prädikat levels. Regardless of sweetness level, the wines share a structural backbone of fine acidity and slate-driven minerality that drives exceptional longevity. Bottles from top producers in great vintages are routinely cellared for decades.

The Prüm family name appears repeatedly among the key estates of Wehlener Sonnenuhr, reflecting the historical ownership patterns of the site. J.J. Prüm is the benchmark producer, widely regarded as making definitive expressions of the vineyard across all Prädikat levels. Dr. Loosen, based in Bernkastel, produces consistently excellent versions and has played a major role in promoting Mosel Riesling to international audiences. Max Ferd. Richter, S.A. Prüm, Zach. Bergweiler-Prüm Erben, St. Nikolaus-Hospital, and Schloss-Lieser round out the roster of significant Sonnenuhr producers, each offering a distinct perspective on the same exceptional terroir.

• J.J. Prüm is the most celebrated producer, with holdings across the full quality range
• Dr. Loosen is a key ambassador for the vineyard in international markets
• Multiple branches of the Prüm family hold parcels, reflecting the vineyard's long family ownership history
• St. Nikolaus-Hospital adds a historic charitable estate dimension to the producer landscape

Wehlener Sonnenuhr occupies a position at the very top of the Mosel hierarchy. It sits within the stretch of riverbank sometimes called the 'magic four miles,' running from Bernkastel to Zeltingen and encompassing many of the region's most storied sites. The vineyard's reputation earned recognition long before modern classification systems existed, with documented excellence since Roman times and confirmation at the highest level in the 1868 Prussian classification. In October 2024, Wine Spectator placed it among the ten greatest vineyards in the world, a recognition that reflects what Mosel specialists have known for generations. The steep, unforgiving terrain and the centuries of investment by committed producers have made Sonnenuhr a reference point not just for German Riesling but for the potential of cool-climate viticulture worldwide.
