Weingut Gunderloch

Weingut Gunderloch is a family-owned German wine estate and producer based in Nackenheim in the Rheinhessen wine region. The estate was established in 1890 by Carl Gunderloch, a banker from Mainz who invested in viticulture during the German Gründerzeit. He acquired the Dalheimer Hof, formerly associated with the secularised Cistercian abbey of Dalheim near Mainz, together with important vineyard holdings including the Nackenheimer Rothenberg on the Roter Hang, or Red Slope, along the Rhine. Through these acquisitions and his emphasis on quality-oriented cultivation, Gunderloch became part of the modern development of premium wine production on the Rhinefront. The estate remained within the founding family, although ownership was divided between Carl Gunderloch’s two daughters after his death. Agnes Hasselbach-Usinger is identified as the current owner and represents the fifth generation of the winery. The following generation has also become involved in wine production: Stefanie Hasselbach married Austrian winemaker Alwin Jurtschitsch and became cellar master at the Jurtschitsch estate in Kamptal, while Johannes Hasselbach assumed winemaking responsibility at Gunderloch after the death of his father, Fritz Hasselbach, in 2016. Gunderloch’s modern profile was shaped particularly by Fritz and Agnes Hasselbach. During the 1970s, Fritz recognised the growing importance of international wine journalism and specialist print media in establishing the reputation of German estates and individual vineyard sites. In 1979, Agnes and Fritz made a major professional commitment to the winery, leaving their former occupations in education and viticultural research and concentrating on the estate full time. Their relationships with influential wine writers, including Stuart Pigott, helped communicate the quality of Gunderloch’s vineyards to a broader international audience. The estate farms approximately 14 hectares of vineyards. Riesling accounts for about 80 percent of plantings, reflecting the variety’s central role in the Rheinhessen and Roter Hang wine tradition. Burgundy varieties account for approximately 6 percent, Silvaner for about 5 percent, and the remainder consists of other specialist plantings. The portfolio includes wines from recognised sites such as Niersteiner Pettenthal and Hipping, vineyards considered capable of producing Grosses Gewächs, the German classification for top-level dry wines. Average yields are reported at approximately 55 hectolitres per hectare. Gunderloch’s positioning combines family continuity, site-specific viticulture and a strong focus on Riesling. Its wines are sold in Germany and exported internationally, with the estate reporting distribution in 34 countries. The winery is also connected to the wider professional wine community through Johannes Hasselbach’s leadership of the Rheinhessen regional association of the VDP from December 2019. The Gunderloch name has an additional cultural association through Carl Zuckmayer’s 1925 comedy The Merry Vineyard, although the portrayal of Nackenheim wine producers as petty bourgeois was reportedly unwelcome to Gunderloch and other local growers.

Weingut Gunderloch was founded in 1890 by Carl Gunderloch, a banker from Mainz who entered viticulture during the German Gründerzeit. He purchased the Dalheimer Hof, originating from the secularised property of the Cistercian abbey of Dalheim near Mainz, as well as notable vineyard land including Nackenheimer Rothenberg on the Roter Hang. These investments placed the estate within the emergence of quality-focused wine production along the Rhine. After Carl Gunderloch’s death, the winery was divided between his two daughters. The business nevertheless remained a family operation and continued across successive generations. Its name later gained an unexpected association with Carl Zuckmayer’s 1925 comedy The Merry Vineyard, which depicted Nackenheim’s wine producers in an unflattering petty-bourgeois light. The portrayal was reportedly disliked by Gunderloch and other local growers. A significant modernisation in the estate’s commercial and professional approach occurred during the 1970s. Fritz Hasselbach, who had trained in Geisenheim, understood that specialist international wine publications could influence the reputation of estates and vineyard sites. In 1979, he and Agnes Hasselbach decided to leave their respective professional positions and devote themselves to the winery. The estate subsequently developed relationships with prominent wine critics, including Stuart Pigott, using professional wine media as an important means of presenting Gunderloch’s vineyards and wines to international audiences. The family’s fifth generation is represented by Agnes Hasselbach-Usinger, identified as the current owner. The sixth generation has also entered the wine business. Stefanie Hasselbach became cellar master at the Jurtschitsch estate in Austria after marrying winemaker Alwin Jurtschitsch. Johannes Hasselbach took over winemaking responsibilities at Gunderloch after his father Fritz died in 2016. Johannes later became head of the Rheinhessen regional VDP association in December 2019, connecting the estate with the region’s principal quality-wine organisation. The estate currently works approximately 14 hectares of vineyards in Rheinhessen. Its holdings include Niersteiner Pettenthal and Hipping, selected sites capable of producing Grosses Gewächs wines. Riesling makes up approximately 80 percent of the planted area, while Burgundy varieties account for about 6 percent and Silvaner for about 5 percent; remaining acreage is devoted to other specialities. Average yields are approximately 55 hectolitres per hectare. Gunderloch sells its wines in Germany and exports to 34 countries, combining a strong regional identity with international distribution.

• 1890

  Estate founded

  [1]Weingut Gunderlochen.wikipedia.org

  Carl Gunderloch established the estate after acquiring the Dalheimer Hof and important vineyard holdings including Nackenheimer Rothenberg on the Roter Hang.

Family-owned, quality-oriented German wine estate focused on site-expressive Riesling from leading Rheinhessen and Roter Hang vineyards.

• Wine

  Riesling

  Riesling is the estate’s principal grape variety, representing approximately 80 percent of its vineyard plantings. Gunderloch’s Rieslings express the character of selected Rheinhessen sites, including vineyards on the Roter Hang and the Niersteiner holdings. The range includes dry wines and vineyard-designated bottlings, with the estate’s top sites capable of producing Grosses Gewächs wines.

• Premium dry wine

  Grosses Gewächs vineyard wines

  These are top-level dry wines made from selected vineyard sites such as Niersteiner Pettenthal and Hipping. The Grosses Gewächs designation places emphasis on origin, vineyard quality and dry-wine production rather than on a mass-market varietal range. At Gunderloch, the category is closely associated with the estate’s premium Riesling identity.

• Wine

  Burgundy varieties

  Burgundy varieties comprise approximately 6 percent of the estate’s plantings. They form a smaller part of the portfolio than Riesling but provide diversification within Gunderloch’s vineyard and wine programme.

• Wine

  Silvaner

  Silvaner represents approximately 5 percent of the vineyard area. It contributes a traditional Rheinhessen variety to the estate’s portfolio alongside Riesling and Burgundy plantings.
