Ried Altweingarten’s vineyards lie at an elevation of 270 to 320 metres and predominantly face south-west. The substratum is characterised by a thick covering of loess with soils of calcareous, silty black earth with a deep root depth. Loess is a calcareous rock dust that was blown here from the Alpine region during the cold phases of the Ice Age, at a time when vegetation was sparse. Since then, it has become a loamy, sandy soil that is invariably calcareous, with a good capacity for storing water. Vineyards are recorded at this location in both the Franziszeische Kataster (Austrian cadastral survey) from 1822 and the Administrativkarte (administrative map, 1864–1881). The plot was referred to back then as “In alten Weingärten”.
