The winery is located in the municipality of Assmannshausen in the German Rheingau wine region. The foundation stone was laid by Josef Kesseler, who took over the former winegrowers' cooperative in Assmannshausen in 1924. His grandson August Kesseler has been responsible for the estate since 1977. He gained practical experience in France, Italy and the USA. The vineyards comprise 20 hectares of vineyards in the individual sites Höllenberg (Assmannshausen), Pfaffenwies and Schlossberg, Seligmacher (Lorchhausen), as well as Berg Roseneck, Berg Schlossberg and Bischofsberg (Rüdesheim). They are planted with more than 50%Pinot Noir (Spätburgunder), some of them with vines more than 70 years old, as well as Riesling and Silvaner. Great attention is paid to yield limitation with first thinning out after flowering as well as selective manual harvesting with healthy, ripe grapes.
After gentle destemming, the red grapes are fermented in the classic way on the mash in open tanks of up to 1,000 litres. The mash cake is carefully pushed under by hand. The red wines are then aged in for 12 to 15 months. The white grapes are gently pressed and fermented in stainless steel at a controlled temperature and then aged. The terroir is to be preserved by strictly separating the individual containers until the assemblage or bottling. Bottle-fermented sparkling wines are also produced. The winery is a member of the VDP (Verband deutscher Prädikatsweingüter) and the German Barrique Forum.
