Why it matters
The producer
S.A. Prüm is a Riesling estate in Bernkastel-Wehlen, where the Prüm family had already been recorded as vineyard owners in 1156. Sebastian Alois Prüm founded the winery in 1911, turning that long connection to vines into the present estate. Saskia A. Prüm has owned and headed it since 2017, with Kilian Klein as cellarmaster. The result is a focused Mosel range in which Riesling carries the name of the estate, its vineyard sites and its VDP classifications.
The family record begins with vineyards in 1156, but the winery itself began in 1911. Raimund Prüm took over from his father in 1971, continuing the estate’s Riesling work in Bernkastel-Wehlen. In 2017, Saskia A. Prüm assumed ownership and leadership. The succession matters in the bottle because the estate remains tied to its Mosel sites while its current cellar team works with both estate-level Riesling and Grosses Gewächs wines from the VDP system.
Place and vineyards
Where the wines begin
Bernkastel-Wehlen sits in the Mosel, and Wehlener Sonnenuhr is the estate’s key named vineyard reference. Its name comes from the large sundial built in 1842 by Jodocus Prüm, a family ancestor. On a label, Wehlener Sonnenuhr is therefore more than a picturesque phrase: it identifies a vineyard in Wehlen and places the Riesling within a specific part of the Mosel rather than a broad regional blend.
The physical facts are steep slopes, hand work and old Riesling stock. S.A. Prüm’s oldest vines in Wehlener Sonnenuhr are ungrafted and date to 1905; harvesting on the estate’s steep ground is done by hand. That combination makes selection in the vineyard a practical part of production, while the old Sonnenuhr vines give the estate a concrete link between its current Riesling and a planting that predates the winery’s modern founding.
In the cellar
Vineyards and cellar
Steep slopes require hand harvesting, so fruit reaches the cellar through a manual selection process rather than a machine pass. For Grosses Gewächs wines, S.A. Prüm uses spontaneous fermentation and traditional Fuder barrels. A Fuder is the large, traditional wooden cask associated with German wine cellars; here it is part of the maturation of the dry top-category wines. Blue occupies a different role as a dry estate Riesling, while the Grosses Gewächs wines receive this documented barrel-cellar treatment.
Wines to know
The range in view
The clearest way into the range is through its VDP structure. Blue is a dry Riesling VDP.Gutswein: the estate-wine tier, made to present S.A. Prüm’s house style rather than one named vineyard alone. It is described as mineral and saline, with dryness keeping the wine firmly in the dry Riesling register.
Above that estate-wine level, the range includes Grosses Gewächs wines. These are the wines connected with spontaneous fermentation and maturation in traditional Fuder barrels. S.A. Prüm also distinguishes its own estate wines from the separate Raimund Prüm range, so the producer name and range name on the label are worth noting before assuming two bottles occupy the same place in the portfolio.
A useful way in
A bottle to begin with
Start with S.A. Prüm Blue Riesling trocken. It is the estate’s dry VDP.Gutswein and gives a direct view of the producer’s Riesling focus without requiring knowledge of a single vineyard hierarchy. Its mineral, saline, dry profile makes the wine’s shape easy to follow: acidity carries the palate, savoury mineral notes hold the centre, and the finish stays dry. Blue also makes the label logic easier to read before moving into the separate Raimund Prüm range or the estate’s Grosses Gewächs wines.
