Summary
DAGERNOVA Weinmanufaktur is the brand of Ahr Winzer eG and thus the largest wine production facility on the Ahr – the smallest and at the same time best-known red wine growing region in Germany. Behind the name stands not a single family but a co-operative of around 600 winegrowing families who together contribute more than 150 hectares of vineyard. At the centre is Spätburgunder (Pinot Noir), flanked by Frühburgunder, Portugieser and a white wine line built around Riesling and the Pinot family. That an operation of this size can compete at the very top became clear in 2025: DAGERNOVA won the Falstaff Co-operative Trophy as Germany's best growers' co-operative. The name itself reaches far back – 'Dagernova' is the earliest documented form of Dernau, a Frankish settlement from the 8th century.
History
The roots reach back to 1873, when growers in Dernau joined forces as the Winzerverein (individual sources give 1871). In 1881 the Weinbauverein Dernau was added, and in 1970 the two merged to form the Winzergenossenschaft Dernau. In the years that followed, the growers' associations of Bachem, Heimersheim, Bad Neuenahr and Rech joined as well – turning a village operation into the largest co-operative in the region. In 1981 the head office moved to Bad Neuenahr, and in 2004 came the renaming to 'Weinmanufaktur Dagernova'.
One point of clarification: the Winzergenossenschaft Mayschoß-Altenahr, the oldest surviving growers' co-operative in the world, is an independent business and does not belong to DAGERNOVA – the two houses are occasionally confused.
Between 2012 and 2022, more than six million euros went into buildings and cellar technology. The company also holds a stake in Weingut Kloster Marienthal.
The deepest rupture came with the flood night of 14 to 15 July 2021. The historic co-operative building with the wine shop in Dernau, sitting directly on the Ahr, was severely damaged and had to be stripped back to the shell; around ten hectares of vineyard were lost, above all on the flat land between Dernau and Rech. An interim wine shop in Bad Neuenahr served as a stopgap. In June 2025 – barely four years after the flood – the new wine shop opened in Dernau: an investment of around four million euros, designed by the architecture office Heinrich + Steinhardt, with an illuminated glass tower and lift, a wine cellar reaching up to 40 metres into the rock, slate as the guiding material and a new tasting room with a terrace. In the region, the reopening was read as a signal of a new beginning.
Location & Terroir
The Ahr is Germany's smallest red wine region – and at the same time the one most readily associated with German Pinot Noir. The vineyards of DAGERNOVA's members are spread across the classic Ahr villages from Dernau via Rech and Walporzheim through to Heimersheim and Bad Neuenahr; a few parcels, roughly three hectares, lie on the Mittelrhein.
Slate is the defining element. It stores warmth, gives the wines their cool, spicy signature, and is so central to the identity here that the new wine shop turned it into a motto: 'shaped by slate'. Alongside it come loess-loam soils, which deliver fuller, softer wines.
One dedicated project carries the name 'Mission Steillage' (steep-slope mission): it focuses on wines from slopes with more than 30% gradient – exactly those parcels that can barely be worked by machine and are therefore under pressure all across Germany. For a co-operative that is a statement of intent, because steep-slope work only pays off if the resulting wines are marketed accordingly.
Style & Philosophy
The style follows the region: clearly red-wine dominated. Spätburgunder is the lead variety, Frühburgunder delivers the denser, smaller-berried version of the same theme, and Portugieser rounds out the red segment. On the white side stand Riesling, Weißburgunder, Grauburgunder and Rivaner. Exact variety percentages are not published by the company.
Structurally, DAGERNOVA is not an estate but a co-operative: around 600 member families deliver grapes, and the wines are made centrally in modernised cellar facilities. Heike Holzapfel chairs the board, alongside board member Dirk Wollersheim. Annual production, according to the available figures, lies at roughly 1.2 to 1.4 million litres – a scale that is exceptional for the Ahr.
In terms of quality tiers, the company works with an internal quality pyramid: from the entry segment through premium wines to the Kult line from single vineyards. There is no VDP membership and no organic certification; on the label, the statutory German quality classification applies, for example Qualitätswein trocken.
Notable Sites & Wines
The top line comes from five single vineyards, each showing the character of its village:
- Dernauer Hardtberg
- Dernauer Pfarrwingert
- Walporzheimer Kräuterberg
- Heimersheimer Kapellenberg
- Bad Neuenahrer Sonnenberg
These sites carry the Kult line, whose wines reach scores of 92 to 94 points. The best-known wine at present is the 2022 Dernau Hardtberg Frühburgunder dry – with 94 points, the winning wine of the Falstaff Co-operative Trophy 2025.
