Weingut Carl Loewen

The Loewen family's connection to the Mosel began in 1803, when a family ancestor working as vineyard manager at the Benedictine Abbey of St. Maximin in Trier seized the opportunity created by Napoleonic secularization. He purchased parcels at auction, including the Maximiner Klosterlay in Detzem, which remains a foundation vineyard of the estate today. Acquisition in 1805 formally established the family's landholding. The estate name honors Carl Loewen, an earlier family patriarch, and the property has remained continuously in family hands across eight generations. Karl-Josef Loewen, father of the current proprietor, expanded the estate significantly during the 1980s and 1990s by purchasing neglected old-vine sites that other producers had abandoned.

• Estate founded 1803 after Napoleonic secularization auction of Benedictine Abbey of St. Maximin church lands
• Maximiner Klosterlay in Detzem, acquired by 1805, is the founding vineyard of the estate
• Karl-Josef Loewen acquired Leiwener Laurentiuslay in 1982 and Thörnicher Ritsch in 1998, expanding the estate into neglected steep-slope sites
• In 2008, the estate acquired the historic Carl Schmitt-Wagner vineyard holding the 1896-planted Maximin Herrenberg parcel

Christopher Loewen represents the eighth generation of the family and took on the role of principal winemaker and proprietor after studying viticulture and enology at the renowned Geisenheim University. He broadened his perspective with harvests in New Zealand and the United States before returning to Leiwen. His father, Karl-Josef Loewen, remains a co-owner and active presence at the estate. The operation is deliberately compact, running with Christopher, his father, and a single full-time employee, with Christopher's wife supporting the business while raising their two children. This lean structure keeps production focused and quality-driven rather than volume-oriented.

• Christopher Loewen trained at Geisenheim University and completed harvest work in New Zealand and the USA before taking charge
• Named Winemaker of the Year by British critic Stuart Pigott and the FAZ newspaper in 2017
• Falstaff recognized the estate's 2015 vintage collection as Collection of the Year in its 2017 guide
• Estate operates as a three-person team; wines are allocated primarily through a mailing list given limited production

Carl Loewen farms 18 hectares across several named sites in the Middle Mosel, with an extraordinary concentration of pre-phylloxera, ungrafted vines that exceed 50% of total plantings. The crown jewel is the 1.4 to 1.5 hectare Maximin Herrenberg parcel in Longuich, planted in 1896 on south-facing red Devonian slate with volcanic inclusions, planted at 10,000 vines per hectare on original ungrafted rootstock. The Thörnicher Ritsch is the second steepest vineyard in all of Germany, planted on gray quartzite slate with historic stone terraces that the estate works to preserve. Additional holdings include the Leiwener Laurentiuslay on gray slate, the Maximiner Klosterlay on blue slate in Detzem, and the Leiwener Klostergarten, which contributes old-vine massal selection fruit.

• Maximin Herrenberg planted 1896, ungrafted, on red Devonian slate with volcanic inclusions; classified Erste Lage (First Growth)
• Thörnicher Ritsch is the second steepest vineyard in Germany, with gray quartzite slate and preserved historic stone terraces; classified Grosses Gewächs
• Over 50% of total 18-hectare estate is ungrafted vines aged 60 to 120 years old
• Maximin Herrenberg yields roughly 40 hl/ha due to vine age and planting density of 10,000 vines per hectare

Loewen's cellar philosophy centers on non-intervention and patience. Fermentations proceed spontaneously with indigenous yeasts, with no temperature control applied, a practice the estate has followed since the 1990s. Mechanical pumping is avoided entirely; all transfers are gravity-fed. Top wines are pressed using a traditional basket press that is over 100 years old and aged in classic Moselian fuder oak barrels. Acids are never corrected, and sulfur additions are kept to a minimum throughout the process. The estate produces both dry Rieslings, including Grosses Gewächs bottlings, and a range of Pradikat sweet wines, with a philosophy that low residual sugar should be a result of complete fermentation rather than a stylistic aim imposed on the wine.

• Spontaneous fermentation with indigenous yeasts; no temperature control used since the 1990s
• Gravity-fed cellar; no mechanical pumps used at any stage of production
• Traditional fuder oak barrels used for top wines; a basket press over 100 years old is used at harvest
• Minimal sulfur additions throughout; acid is never corrected; all fruit is 100% estate-grown

Weingut Carl Loewen occupies a singular position in German wine because it preserves something most estates can no longer offer: pre-phylloxera, ungrafted Riesling vines producing fruit on their original rootstock, farmed by the family that has tended them for generations. The 1896 Maximin Herrenberg bottling, named for the year of planting, is one of the most discussed dry Rieslings in Germany, recognized by critic Stuart Pigott as one of the best dry white wines in the world. Beyond the headline vineyard, the estate demonstrates that extreme-slope viticulture in the Mosel, when combined with rigorous low-intervention winemaking, produces wines of remarkable tension and longevity. For students of German wine, Loewen illustrates the intersection of terroir classification (Erste Lage, Grosses Gewächs), historic viticulture, and the evolving identity of dry Mosel Riesling.

• 1896 Maximin Herrenberg is among the oldest continuously producing ungrafted Riesling vineyards in the world
• Stuart Pigott described Maximin Herrenberg as 'in a class of its own' and 'one of the best dry white wines of the world'
• Estate holds both Erste Lage and Grosses Gewächs classifications, spanning the VDP quality pyramid for dry and Pradikat wines
• Eichelmann 2024 awarded the estate 5 stars; Pearl 2-Star Prestige confirmed for 2025
