Single location in the municipality of Hattenheim in the German Rheingau wine growing region. There are different interpretations about the origin of the name. According to one variant it is derived from "Wiesel" or "meadow". According to a second variant, however, it is a corruption of the Latin "fistula", which means tube and refers to the well located there. The vineyards, facing south to southwest, at an altitude of 100 to 120 metres above sea level with an 8% slope, cover 18 hectares of vines. The medium-heavy tertiary marl soils with calcareous loess loam have an excellent water retention capacity. The Riesling variety is mainly cultivated here. The Barth Norbert, Eser August, Freiherr Langwerth von Simmern, Georg Müller Stiftung, Kaufmann Urban, Rüdesheimer Sektkellerei Ohlig, Schloss Reinhartshausen, Schloss Schönborn and Spreitzer Andreas & Bernd, for example, have shares in the site.
