The winery is located in the municipality of Dernau in the German Ahr wine region. It was founded in 1910 by Gottfried Sebastian. Since 1998, the fourth generation of the family, the sisters Andrea Bertram and Ricarda Sebastian, have been running the winery. After an internship at the Meyer-Näkel winery in Dernau (2009), the completion of the studies of viticulture and oenology as "Bachelor of Science" at the University of Applied Sciences Geisenheim (2012) and the function of "German Wine Queen" as ambassador of German wine (2013), daughter Julia Bertram vinified the first wine line of 1.3 hectares of vineyards in 2014.
The vineyards cover 3.5 hectares of vineyards in the individual locations Burggarten, Hardtberg, Pfarrwingert and Schieferlay (Dernau), Mönchberg (Mayschoss) and Trotzenberg (Marienthal), Daubhaus, Forstberg and Rosenthal (Ahrweil), as well as Kirchtürmchen and Sonnenberg (Bad Neuenahr). They are 95%Pinot Noir and some early Pinot Noir. Because of the steep slopes only handicraft is possible. A reduction in yield or an increase in quality is achieved through the measures of defoliation, grape splitting and thinning out. Through 100% selective hand harvesting, only ripe and healthy grapes are processed.
Through gentle processing, the wines should reflect the soil, the weather, the work in the vineyard, the vintage and the signature of the winemaker. The wines are fermented spontaneously without the use of pure yeasts and matured for a long time in wooden barrels of various sizes. The premium wines are the two Spätburgunder Mönchberg and Trotzenberg. 20,000 bottles of wine are produced annually.
