Summary
Weingut Franz Keller in Oberbergen is today one of the best-known and highest-rated addresses in Baden. Across around 49 hectares – more than two thirds of them Burgundy varieties – it produces fully dry-fermented wines from the volcanic sites of the Kaiserstuhl. What makes the estate unmistakable is its signature: the Pinots are vinified in the Burgundian mould and aged in a three-storey gravity-flow cellar built into the hillside, giving them precision, depth and ageing potential. The Spätburgunder (Pinot Noir) is the flagship – and makes Franz Keller one of Germany's leading Pinot producers. Added to this is a rare unity of wine estate and the starred restaurant „Schwarzer Adler".
History
The Keller family's roots reach back to around 1900, when a winegrowing business developed around the „Schwarzer Adler" inn in Oberbergen. The defining figure of the modern estate, however, was Franz Keller senior (1927–2007): in Germany he was among the pioneers of fully dry-fermented wines and barrique ageing – at a time when off-dry wines dominated the market. In doing so he laid the foundation for the Burgundian-inspired style the estate still stands for today.
From 1990, Fritz Keller took over the management and consistently built the estate up to the national top – while also making a name for himself as a restaurateur and later as president of the German Football Association. Since 2016, his son Friedrich Keller has led the estate as the fourth generation, continuing the precise, terroir-focused style.
Location & Terroir
Franz Keller lies in the Kaiserstuhl, a small volcanic range in the Upper Rhine plain and one of the warmest and sunniest wine regions in Germany. The distinctive subsoil is decisive: volcanic rock – including tephrite – meets thick layers of loess, which store warmth and provide water to the vines even in dry years.
This interplay of volcanic origin, loess and the mild Upper Rhine climate produces ripe yet taut, structured wines. The south-facing terraced sites capture plenty of sun, while the cool nights ensure freshness and aromatic definition. It is exactly this balance that forms the basis for the estate's Burgundy-variety wines – full-bodied but never heavy.
Style & Philosophy
The stylistic core idea at Franz Keller is to treat Burgundy varieties as they are in their homeland, Burgundy. The wines are fully dry-fermented and aged for many months – the top wines in barrique, the base wines gently in larger wood or stainless steel. At the heart is the spectacular three-storey gravity-flow cellar built into the hillside: must and wine move largely by gravity, without mechanical pumps – gentle on both grapes and wine.
More than two thirds of the vineyard area is planted with Burgundy varieties. The Spätburgunder is the flagship and ranks among Germany's finest Pinot Noirs, but Grauburgunder, Weißburgunder and Chardonnay also enjoy an excellent reputation. The range is clearly tiered – from the accessible entry line „Vom Löss" to the Große Gewächse.
Notable Vineyards & Wines
The range runs from the accessible „Vom Löss" line through village and single-site wines to the Große Gewächse from the best parcels. Among the estate's most famous sites are:
- Oberbergener Bassgeige – one of the flagship sites for Spätburgunder and Grauburgunder
- Achkarrer Schlossberg – a famous terraced site on volcanic soil
- Oberrotweiler Eichberg and Oberrotweiler Kirchberg – distinctive Kaiserstuhl sites
- Oberbergener Pulverbuck
- Jechtinger Enselberg
The Große Gewächse from these sites regularly rank among the highest-rated dry Burgundy-variety wines in Germany.
Awards
Franz Keller consistently collects top marks in the leading wine guides and international tastings and is regarded as one of the flagships for German Pinot Noir. Inseparably linked to the estate is the restaurant „Schwarzer Adler", which has held a Michelin star since 1969 – one of the longest continuous holdings in Germany. Fritz Keller himself was named „Restaurateur of the Year" by Gault&Millau. This unity of top wine estate and starred cuisine makes the estate a special address on the Kaiserstuhl.
