Ried Bergthal’s vineyards vary in elevation between 250 and 300 metres and predominantly face south-east. The vines here grow on quartz-rich, sandy gravels from the Hollabrunn-Mistelbach formation. These are approximately 8- to 10-million-year-old sedimentary deposits from the ancient Danube, which once flowed into the Vienna Basin, following a course somewhat to the north of the present-day river. There is loess in the central part and around the edge of the Ried. 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. The vineyard is warm, sheltered from the wind and planted predominantly with Zweigelt, St. Laurent and Grüner Veltliner. Vineyards are recorded at this location in both the Franziszeische Kataster (Austrian cadastral survey) from 1822 and the Administrativkarte (administrative map, 1864–1881). The name of today’s plot was already in use back then.
