Weingut Forstmeister Geltz-Zilliken

The Zilliken family's connection to the wine trade traces to 1742, but the modern estate took shape in the 1890s under Ferdinand Geltz (1851 to 1925), a Royal Prussian Forester who established the winery and gave it his name. Ferdinand's legacy extends well beyond the Saar: in 1908 he co-founded the VDP, the Verband Deutscher Prädikatsweingüter, the association of elite German wine estates that still sets the benchmark for quality classification in the country. The original cellars sat on the opposite bank of the Saar River and were destroyed by bombing in December 1944; the current multi-story cave-like cellar was built in 1950, with the family residence added in the 1960s. The natural conditions within those rebuilt cellars, constant temperature and high humidity without mechanical intervention, have shaped the patient, unhurried winemaking philosophy the estate maintains to this day.

• Family wine trade roots documented to 1742; modern winery founded by Ferdinand Geltz in the 1890s.
• Ferdinand Geltz co-founded the VDP in 1908, establishing Zilliken as one of Germany's elite wine estates from the organization's inception.
• Original cellars destroyed in bombing December 1944; current cellars built 1950 at current Saarburg headquarters.
• Estate is a member of the Bernkasteler Ring, a historic wine auction consortium for top Mosel-Saar-Ruwer producers.

Hanno Zilliken took responsibility for the estate beginning with the 1976 vintage and spent the following three decades building its international reputation as a benchmark for Saar Riesling's hallmark lightness and transparency. His daughter Dorothee began working alongside him in 2007 after studying at Geisenheim and gaining experience in the Pfalz and South Africa, and she assumed full lead winemaking responsibility in 2016. Today, Dorothee and her husband Philipp manage the estate day to day, with Hanno and his wife Ruth providing ongoing guidance; this tight family structure means the winery runs with just one full-time and two part-time employees. In 2017, the transition generation was recognized together when Gault Millau named Hanno and Dorothee jointly as Winemaker of the Year and awarded the estate its highest five-grape rating, one of only 13 producers in Germany to receive that honor.

• Hanno Zilliken took over from the 1976 vintage; Dorothee became lead winemaker in 2016 after training at Geisenheim and working in the Pfalz and South Africa.
• The estate now represents the 10th generation (Hanno) and 11th generation (Dorothee) of family ownership.
• Gault Millau named Hanno and Dorothee jointly Winemaker of the Year in 2017, with a 5 out of 5 grape rating placing Zilliken among only 13 German producers at that level.
• Total workforce is one full-time and two part-time employees; all production uses exclusively estate-grown fruit with no purchased juice or must.

The estate farms 13 hectares across two VDP Große Lage sites, the German equivalent of Grand Cru. The Saarburger Rausch is the heart of the estate, covering 11 hectares of steep, south-facing slopes above Saarburg where Devonian slate, diabase (a rock of volcanic magma origin), and quartz dominate the soil profile; vine roots penetrate this fractured slate to depths of 10 meters. The second site, Ockfener Bockstein, lies in the neighboring village of Ockfen and contributes 1 to 2.5 hectares of gray slate, quartz, basalt pockets, and clay. Both sites impose serious physical demands: harvesting on these gradients requires entirely manual work. Vine age adds further intensity to the raw material, with many parcels planted between 60 and 130 years ago, and estate-wide average vine age exceeding 30 years.

• Saarburger Rausch: 11 hectares, VDP Große Lage, steep south-facing Devonian slate and diabase slopes; vines root to 10 meters depth.
• Ockfener Bockstein: 1 to 2.5 hectares, VDP Große Lage, gray slate with basalt pockets, quartz, and clay in neighboring Ockfen.
• Average vine age across the estate exceeds 30 years; select parcels contain vines 60 to 130 years old.
• The Saar Valley totals just 735 hectares, representing 1.7 percent of the Mosel's 8,800 hectares, making Große Lage sites here among the rarest in German wine.

Every wine at Zilliken is fermented and aged in 1,000-liter Fuder casks, the traditional large-format neutral German oak barrel used historically throughout the Mosel. Many of the estate's Fuders are between 50 and 70 years old, contributing negligible oak flavor while allowing gentle micro-oxygenation during the extended, often slow fermentation driven entirely by wild yeast. The cellar temperature holds at a constant 11°C (48°F) with humidity ranging from 55 to 95 percent, conditions achieved naturally without refrigeration and critical to the unhurried pace at which these wines develop. The portfolio spans the full spectrum of VDP Prädikat categories, from the delicate and low-alcohol Kabinett through Spätlese, Auslese, and into Beerenauslese at the noble-sweet end, with Goldkapsel (Gold Cap) Auslese wines released through auction. Entry-level access comes through the Butterfly label, an off-dry Gutswein introduced in 2002. Across all levels, the house style prizes transparency, mineral precision, and a near-weightless texture that the family describes as butterfly-like.

• Fermentation exclusively in 1,000-liter Fuder casks, many 50 to 70 years old; only around 10 Mosel estates use this method; one craftsman in Germany makes Fuders with a three-year waiting list.
• Wild yeast fermentation only; no inoculated commercial yeasts used across any wine in the portfolio.
• Cellar constant at 11°C with 55 to 95 percent humidity achieved via natural cave conditions, no mechanical refrigeration.
• Range spans Kabinett to Beerenauslese; Goldkapsel Auslesen released at auction; Butterfly Gutswein (introduced 2002) provides off-dry entry-level access.

Zilliken occupies a position in German wine that few estates can claim: it is both a historical anchor, with co-founding membership in the VDP dating to 1908, and a living standard-bearer for what the Saar does better than anywhere else on earth. The Saar's cool continental climate and fractured slate soils produce Rieslings of uncommon nerve and tension, and Zilliken's patient cellar methods amplify those qualities into wines capable of evolving for 30 years or more. The estate's boutique scale, around 75,000 bottles per year from 13 entirely self-farmed hectares, means demand reliably outpaces supply. Collectors prize the Goldkapsel Auslesen released through auction; students of German wine use the full Prädikat range as a textbook illustration of how ripeness levels interact with site character. The 2024 vintage, marked by severe frost that destroyed up to 80 percent of some parcels, underlines the precariousness of Saar viticulture and the discipline required to maintain quality in difficult years.

• Co-founding VDP membership since 1908 makes Zilliken one of the oldest continuous members of Germany's most important quality wine association.
• Production of approximately 75,000 bottles annually from 13 self-farmed hectares with no purchased fruit; demand consistently exceeds supply.
• Goldkapsel Auslesen sold through auction represent some of Germany's most collectible sweet Rieslings, with aging potential of 30 or more years.
• 2024 frost destroyed up to 80 percent of crop in some parcels, resulting in one of the smallest harvests on record and highlighting the climatic risk inherent to Saar viticulture.
