Ried Amonsthal consists of four different sections, vary in elevation between roughly 230 to 300 metres towards the Hausberg. The vineyards have a predominant southern orientation. The substratum contains clays and silts that were deposited here some 17 million years ago in the sea that covered the foothills of the Alps at that time. They are covered to a large extent by loess. 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. Vineyards are recorded at this location in both the Franziszeische Kataster (Austrian cadastral survey) from 1822 and the Administrativkarte (administrative map, 1864–1881).
