The winery is located in the municipality of Weinolsheim (Nierstein area) in the German wine-growing region of
Rheinhessen. The traditional family has been growing grapes since 1725. Today, Erich and Eric Manz are the eighth generation of the family to run the winery. The vineyards cover 20 hectares of vines in the single vineyard sites
Herrenberg and
Sackträger (Oppenheim),
Hipping (Nierstein), Kehr (Weinolsheim), Kreuz (Dienheim), Kranzberg (Dalheim), Schloss (Uelversheim) and Steig-Terrasse (Guntersblum). They are planted with the white wine varieties Riesling, Pinot Blanc, Pinot Gris, Chardonnay, Müller-Thurgau, Silvaner, Gewürztraminer, Huxelrebe, Kerner and Ortega, as well as with the red wine varieties Pinot Noir, Pinot Noir, Blauer Portugieser and Dornfelder. The grapes are processed very gently after selective harvesting.
The quality pyramid comprises three lines: estate wines (pure varietal basic quality),
terroir wines (loess, clay marl or limestone) and, at the top, the "Collection Manz" site wines. The cool-fermented white wines are matured in steel tanks, the red wines in traditional wooden barrels or in barriques after four to eight weeks of
maceration. In years with suitable weather conditions,
Trockenbeerenauslese and
ice wines are also vinified. Bottle-fermented sparkling wines are also produced. Around 150,000 bottles of wine are produced annually. The winery is a member of the Pro Riesling Association.
In 2003, the vineyard of the
Protestant Church of Hesse and Nassau was leased. These wines are marketed with their own label.
