Riede (also Olm) in the Austrian wine-growing region Wien in the 19th district of Döbling in the cadastral municipality of Nußdorf, which belongs to Großlage Nußberg. The vineyard was classified by the WV WienWein as 1 ÖTW (Erste Lage of the Traditional Wine Estates of Austria). Ulm is the designation for a particularly favourable limestone soil, Olm for rotten tree mountain. The southeast-facing vineyard directly next to the Danube with a slope of 2 to 23 degrees at an altitude of 207 to 251 metres above sea level covers 3.5 hectares of vineyards. The soil consists of extremely calcareous shell limestone (Tertiary remains of a coral reef) with limestone in the subsoil and a small amount of clay. The typical varieties of the Wiener Gemischter Satz are cultivated, some of them with very old vines. Shares in the vineyard are held by the Hajszan-Neumann and Wieninger wineries.
Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.Thomas Götz
