At the foot of the Horn, Altenberg is right in the middle of the Wolxheim wine-growing area: 31.20 ha which are remarkably exposed, benefiting from an ideally, very dry microclimate at an altitude of 200 to 250m. In the Wolxheim fault area, this terroir with early to middle Jurassic period rock formations is composed of stony-rich marl-limestone.
Altenberg specifically favours Riesling grapes which cover about 18 ha. Gewurztraminer is also present with 8 ha.
Numerous archived medieval documents recount the interest of religious congregations for the Wolxheim wine-growing area: the Strasbourg bishopric (bishop Wernher in 1003), the Hohenbourg Abbey (Saint Odile 1188), the Benedictines of Altdorf (1192) and the Strasbourg hospital (register of goods in 1320) all owned a large part.
More recent accounts are just as impassioned: Auguste Stoeber, J.-L. Stoltz, Charles Gérard and Médard Barth all individually glorify the area. As well as De Grandidier, the bishopric archivist and historian:
Wolxheim wine is famous. It was much appreciated by the Emperor Napoleon I. Altenberg produces a high-quality wine: the well-known Riesling.
Altenberg de Wolxheim wines are both gastronomic and age wonderfully, with delicious and generous character. Over the years they develop an intense and harmonious body with fine aromas, specific to its marl-limestone terroir.
