Geography and Microclimate
The site is compact, covering roughly five hectares. Official register figures sit near 5.1 hectares, while growers report closer to 5.5, and the parcel is shared by only two estates. It lies at the western, upper edge of Kallstadt's vineyards, directly beside the Kreidkeller and hard against the treeline, the youngest and smallest of the village's named sites.
That forest boundary defines the terroir. Shade and cool air drainage off the wooded slope make the Annaberg measurably cooler than the warm, open vineyards lower in the village, so ripening runs late and picking often comes well into autumn. The reward is slow, even maturation that preserves acidity and aromatic detail rather than simply accumulating sugar.
Soils
Buntsandstein, the red sandstone of the Haardt, dominates the surface as weathered scree, lying over a calcareous base of limestone marl and limestone rock. This pairing of sandstone with a chalky subsoil sets the Annaberg apart within Kallstadt, whose most celebrated sites are more overtly limestone driven, and it lends the wines a tension between stony coolness and underlying depth.
Grapes and Style
Riesling is the flagship, but the walled parcel also holds old Weissburgunder and Chardonnay, among the oldest such plantings in the district, as well as Scheurebe, which Koehler-Ruprecht still bottles from the site. Riesling from the Annaberg tends toward the smoky, herb-tinged and mineral rather than the overtly fruity, with restrained yellow fruit and a saline, structured finish built for the cellar rather than for early drinking.
Producers
Two growers share the Annaberg. Weingut Rings, run by brothers Steffen and Andreas Rings and a VDP member since 2015, farms around 44 hectares across the Mittelhaardt and bottles the Annaberg Riesling as a Grosses Gewaechs, one of the estate's four Grosse Lagen alongside Saumagen, Weilberg and Felsenberg. Koehler-Ruprecht, the traditionalist Kallstadt house, works the other portion, drawing its Weissburgunder, a Chardonnay and a Scheurebe from these old walled rows.
In Context
Within Kallstadt the Annaberg stands apart from the village's grander names. The Saumagen, a former chalk quarry, is broader, warmer and more powerful. The Steinacker sits lower and more open. The Annaberg, smaller, cooler and hemmed in by forest, trades sheer weight for freshness and precision, offering the coolest and most reticent expression of Kallstadt Riesling.
