The traditional family business is located in the municipality of Vogtsburg-Oberbergen in the German wine-growing region of Baden. It comprises the "Franz Keller" winery, the "Schwarzer Adler" and "KellerWirtschaft" restaurants, the "Schwarzer Adler" hotel, the Winzerhaus Rebstock and an import wine trade. Senior Franz Keller made his mark for decades as an opponent of land consolidation in 1971, in his pioneering role in the introduction of Pinot Gris, and as a promoter of barrique ageing and fully fermented, dry wines. The business is run by Fritz Keller and his son Friedrich Keller. With over a hundred years of history, the wine trade with, for example, French wines from prestigious wine estates in Bordeaux and Burgundy forms an important pillar.
Restaurants
The "Schwarzer Adler" restaurant has been awarded a Michelin star since 1969. In addition to a large selection of wines from the restaurant's own vineyard, guests can choose from around 2,700 of France's best wines as well as German and international classics. The "KellerWirtschaft" offers internationally inspired cuisine. In addition to the view of the wine press house, you can enjoy a fantastic view of the typical Kaiserstuhl terraced landscape and the Badberg nature reserve. In the "Rebstock" winegrower's house, the cuisine is characterised by the Baden-Alsatian style.
Vineyards and grape varieties
The vineyards cover 35 hectares of vines in the single vineyard sites Bassgeige (with the vineyards Im Leh and Kähner) and Pulverbuck (Oberbergen), Eichberg (Oberrotweil), Enselberg (Jechtingen), Kirchberg (Oberrotweil) and 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). Environmentally friendly, gentle viticulture is practised with organic fertilisation, exclusively mechanical soil cultivation and cover crop for the purpose of natural humus supply. Quality-enhancing yield reduction is achieved by thinning out and dividing the grapes.
Wine lines
The winery building has several storeys and is sunk into the loess. Processing is carried out by gravity. The white estate wines are vinified in stainless steel, the white wines of the Oberbergener Bassgeige VDP.Erste Lage in traditional large wooden barrels and in stainless steel tanks and the white wines of the Oberbergener Bassgeige VDP.Erste Lage in traditional large wooden barrels or in stainless steel tanks.

Around 400,000 bottles of wine are produced each year. Bottle-fermented sparkling wines and brandies (fruit, marc) are also marketed. The winery is a member of the VDP (Verband Deutscher Prädikatsweingüter).
