The traditional family business is located in the municipality of Vogtsburg-Oberbergen in the German wine-growing region of Baden. It includes the winery "Franz Keller", the restaurant "Schwarzer Adler", the hotel "Schwarzer Adler", the restaurant "KellerWirtschaft", the vintner's house "Rebstock" and an import wine trade. For decades, Franz Keller, the winery's senior, set the tone as a feared opponent of the large-scale land consolidation in 1971, in his pioneering role in the introduction of the Pinot Gris, as well as a promoter of barrique aging and fully fermented, dry wines. Today, the winery is run by Fritz Keller and his son Friedrich Keller.
With a history spanning over a hundred years, the wine trade forms an important pillar of the company. First-class Bordeaux and Burgundy wines from the most prestigious wineries are still among the trademarks today. The restaurant "Schwarzer Adler" has been awarded a Michelin star since 1969. In addition to a large selection of wines from the own vineyard, one can choose from about 2,700 positions the best wines of France as well as German and international classics. The "KellerWirtschaft" offers modern, internationally inspired cuisine. In addition to the view into the wine press house, you can enjoy a fantastic view of the typical Kaiserstühl terraced landscape as well as the Badberg nature reserve. In the winery house "Rebstock" the cuisine is Baden-Alsatian influenced.
The vineyards cover 35 hectares of vineyards in the single vineyards Bassgeige (with vineyards Im Leh and Kähner) and Pulverbuck (Oberbergen), Eichberg (Oberrotweil), Enselberg (Jechtingen), Kirchberg (Oberrotweil) as well as Schlossberg (Achkarren). They are planted with the white wine varieties Pinot Gris, Pinot Blanc, Chardonnay and Müller-Thurgau, as well as the red wine varieties Pinot Noir, Merlot, Cabernet Sauvignon and Lemberger (Blaufränkisch) are planted. We practice environmentally friendly, gentle viticulture with organic fertilization, exclusively mechanical soil cultivation and cover crop quality-increasing yield reduction is achieved by thinning out and dividing the grapes.
The winery building is sunk several stories into the loess. The processing is done by gravity. The white estate wines are vinified in stainless steel, the white wines of the Oberbergener Bassgeige VDP.Erste Lage are vinified proportionally in traditional large wooden bar rels and in stainless steel tanks, and the Grossen Gew ächse are vinified in traditional large wooden barrels or in Burgundian pièce-barrique bar rels, as well as the Pinot Noirs in principle in barrique.
Following the VDP classification model, the extensive product range is divided into the lines "Jeden Tag" (cuvées for every day, light uncomplicated wines), estate wines (from loess-dominated, lighter soils), Erste Lage (Bassgeige and Pulverbuck), Franz Anton (single-vineyard cuvées from old vines at various altitudes, as a tribute to Franz Anton Keller) and Grosse Lage(Grands Crus from the volcanic rock, made from the best, strictly selected grapes from the Schlossberg, Kirchberg, Eichberg and Enselberg vineyards, as well as the "Im Leh" and "Kähner" vineyards). Around 400,000 bottles of wine are produced annually. Other products are bottle-fermented sparkling wines and noble brandies (fruit, marc). The winery is a member of the VDP (Association of German Prädikat Wine Estates).
