Biodynamic. The Altenbourg vineyard is situated directly beneath the Grand Cru Furstentum. With its identical geology of limestone, clay and some sand, as well as the striking quality of its wines, the site presents a strong argument for Grand Cru status. Domaine Weinbach makes several wines from the Altenbourg, including some stunningly complex late-harvest Pinot Gris and kaleidoscopic Gewürztraminer. This wine tends to be a touch drier and perhaps more savoury than its Furstentum counterpart below, although the 2021 offers plenty for the hedonistic wine lover. Raised for 10 months, this 2021 finished with a balanced 25 g/L residual sugar.
