Ried Exlberg lies to the north of Oberstockstall on the boundary with Ottenthal. The vineyards vary in elevation between around 240 and 270 metres and predominantly face south-west. Lime-deficient to non-calcareous sandy gravels lie at the very bottom of the substratum at the edge of the Krampugraben river. These are evidence of a former river valley floor and can also be found in the substratum of the plateau, which is covered with loess and black earth. Loess is a calcareous rock dust (silt) that was blown here from the Alpine region during the cold phases of the Ice Age, at a time when vegetation was sparse. Today, it forms a loamy, sandy soil that is invariably calcareous, with a well-balanced chemical and mineralogical composition and a good capacity for storing water. Grüner Veltliner is the predominant variety grown here, although red wine varieties are planted here, too. The vineyards are recorded in both the Franziszeische Kataster (Austrian cadastral survey) from 1822 and the Administrativkarte (administrative map, 1864–1881). The name of the plot is still in use today. Ried Exlberg’s name was previously spelled “Echselberg” or “Exelberg”. The word Echsel refers to young oxen that were brought to pasture on this mountain, hence the name of the Ried.
