The winery is located in the municipality of Piesport (Bernkastel area) in the German Moselle
wine region. The traditional family has been growing wine since the 17th century. Attached to the winery are the Straußwirtschaft "WeinOase" and four guest rooms. Since 1980 Lothar Kettern and his wife Petra have been running the winery; since the 2008 vintage son Philipp has been working in his parents' business. The vineyards cover 6.5 hectares of vines in the steep areas of the individual sites Falkenberg, Goldtröpfchen
and Günterslay (Piesport). They are mainly planted with Riesling, as well as Müller-Thurgau, Pinot Blanc and Pinot Noir. The quality criteria in the vineyard are short pruning with only one arch with six to nine eyes, targeted defoliation of
the grape zone and selective manual harvesting, often in several passes, with the aim of producing loose, small-berry, healthy grapes with optimum physiological ripeness
and a maximum yield of 60hl/ha (in some cases a maximum of 40hl/ha is achieved)
In the cellar great importance is attached to a strictly gentle grape processing. The focus in the development is on residual sweet Riesling wines with a pronounced site character. All wines are fermented spontaneously
without the use of any pure yeasts. For the white wines, this takes place slowly and in a controlled manner in steel tanks at cool temperatures of about 12 °Celsius. The red wines are partly aged in large wooden barrels and partly in small barrique barrels. Before bottling, the wines are filtered only once. Through strictest manual selection of the grapes, Beerenauslese and Trockenbeerenauslese grapes form the noble sweet top of the Rieslings almost every year. Bottle-fermented sparkling wines and grape juices (red, white) are also produced.
