Rottensteiner produces wines from Südtirol–Alto Adige, the Alpine region where cool nights and mineral soils shape distinctive expressions of local and international varieties. The winery's portfolio centers on grapes native to the territory: Vernatsch, a light red with regional character, and Lagrein, which yields deeper, structured wines in the Gries style. Alongside these, Gewürztraminer appears in the Cresta Traminer Aromatico Passito, a late-harvest expression that captures the aromatic intensity the variety achieves at altitude. Wines from Rottensteiner have been assessed by Falstaff, Wine Enthusiast, Wine Spectator, and Decanter, reflecting the winery's presence within serious wine criticism. The Cresta Traminer Aromatico Passito and Select Lagrein Gries Riserva represent the upper range of the range, while the Lena Südtiroler Vernatsch anchors the portfolio in regional tradition.
