The winery is located in the community of Birkweiler (area Südliche Weinstraße) in the German wine-growing region
Pfalz. It was founded after the First World War by Karl Wehrheim, who introduced bottling very early on. His son Dr. Heinz Wehrheim continued to expand the business. After completing a degree in general agricultural sciences and a year of practical training in the USA, the estate has been managed by the third generation of the family, Dipl. Agraringenieur Karl-Heinz Wehrheim, since 1992. The fourth generation is already working on the farm. The vineyards are located on 30% steep slopes and comprise a total of 14 hectares of vineyards in 11 different plots. The majority of these are located in the Birkweiler single vineyards
Kastanienbusch (7 ha) and
Mandelberg (1.6 ha Pinot Blanc). They are planted with the white wine varieties Riesling (45%), Pinot Blanc, Pinot Gris, Chardonnay, Silvaner, Gewürztraminer and Muscatel, as well as the red wine varieties Pinot Noir, St. Laurent, Merlot and Cabernet Sauvignon
The vineyards are cultivated according to the guidelines of
Biodynamic viticulture. Depending on the type of wine, the wines are aged in steel tanks or wooden barrels. The aim is to achieve a fine varietal aroma, fruity tartaric acid and very good storage life. The natural aromas are to be rounded off by the dosed use of barriques (obligatory for red wines). The wines from the two
VDP-classified sites Kastanienbusch and Mandelberg are marketed as
Grosses Gewächs. Bottle-fermented sparkling wines and fine spirits (marc, fruit, wine) are also produced. The winery is a member of the
VDP (Verband deutscher Prädikatsweingüter), a founding member of the Vereinigung Sektgüter Rheinpfalz (VSR) and a member of Fünf Freunde aus der Südpfalz.
