The winegrowers' cooperative "Collegium Wirtemberg - Weingärtner Rotenberg & Uhlbach eG" is located on the outskirts of Stuttgart (Remstal-Stuttgart area) in the German growing region of Württemberg
. It was founded in July 2007 by merging the Rotenberg and Uhlbach cooperatives. The wine cellar is located in Württembergstraße at the end of the Untertürkheim district. After studying viticulture and oenology in Geisenheim, Dipl. Ing. Martin Kurrle is responsible as managing director and cellar master. More than 200 members cultivate 125 hectares of vines in the Schlossberg (Rotenberg) and Götzenberg (Uhlbach) vineyards. About three quarters of the vineyards are planted with the red wine varieties Trollinger, Pinot Noir, Frühburgunder, Samtrot, Schwarzriesling, Lemberger, Cabernet Sauvignon, Merlot, St. Laurent, Acolon, Dornfelder, Heroldrebe, Portugieser and Syrah, and about one quarter with the white wine varieties Riesling, Silvaner, Weißburgunder, Grauburgunder, Müller-Thurgau, Kerner, Traminer, Chardonnay and Sauvignon Blanc. The white wines are matured in steel tanks or wooden barrels. The red wines mature after mash fermentation and BSA in classic wooden barrels and partly in barrique. The large product range includes wines in the lines Classic (Collegiumweine, Lagenweine), Edition Wirtemberg, Life Style, Kult (Barrique) and sweet wines. In suitable years, ice wines are also pressed. Bottle-fermented sparkling wines and noble spirits (marc, wine) are also produced.
