Location and history
Rosenberg is a documented vineyard site south of Zunzingen, a district of Müllheim in the Markgräflerland. The site belongs to the winegrowing region Baden. Historical records from 1752 and 1754 already list Rosenberg as a Zunzingen vineyard plot.
Altitude and soils
The vineyard rises to about 380 metres above sea level. The plot documented for Wasenhaus is described as steep and oriented to the southwest. In the sun-exposed Rosenberg vineyards, deep-rooting loess and clay soils predominate; the named Zunzingen plot, by contrast, has shallow, low-nutrient soils on weathered limestone.
Grape varieties and wines
From Rosenberg, wines made from Spätburgunder, Weißburgunder, Grauburgunder and Chardonnay are documented. The Britzingen winegrowers’ cooperative produces a dry Spätburgunder Qualitätswein and a dry Weißburgunder Qualitätswein under the name Britzinger Rosenberg. Wasenhaus produces, from the documented plot, a Zunzinger Rosenberg Spätburgunder.
Cultivation and ageing
For the Britzingen winegrowers’ cooperative’s Rosenberg Spätburgunder, hand-harvest is documented; the wine is prepared with whole grapes using macération carbonique. For Wasenhaus’s Zunzinger Rosenberg Spätburgunder, 80 per cent whole grapes are used, followed by an initial carbonic acid maceration, fermentation in an open fermentation tank with limited pigeage, and 15 months in used French oak barrels. The climate of the wine-growing sites in Britzingen combines warmth, coolness and wind, with cool nights and long growing periods.
