The vineyards of Ried Diebsnest lie on a plateau, which merges into a basin. The vineyards range in elevation between 270 and 320 metres and predominantly face south-west. The substratum is characterised by the quartz-rich, sandy gravels of the Hollabrunn-Mistelbach formation, which appear in many places beneath the loess covering. 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. The soil here is stony, dry and less calcareous than on the powdery, silty loess. Vineyards are recorded at this location in both the Franziszeische Kataster (Austrian cadastral survey) from 1822 and the Administrativkarte (administrative map, 1864–1881). The north-westernmost part of the Ried was already referred to as “In Diebsnest” back then.
