The origin of the site's name is open to theory. On the one hand, Wisselbrunnen could derive from "Wiesel," i.e. weasel, or "Wiese," meaning meadow. Others see an affinity with the Latin "fistula," or pipe(s), in reference to the "Brunnen," or spring, located there. The vineyard lies 100 meters/328 feet above sea level and faces south-southwest, an optimal position for absorbing solar radiation. Wisselbrunnen's light, Tertiary marl soils have a good water balance so that even in very dry years, grapes can ripen extremely well.
