Each summer the Purkhart family picks fresh green walnuts from wild stands of the delicate "Weinsberg" variety near the village of Sankt Peter in der Au. These walnuts steep for months in grape brandy and for the last month with a variety of spices and alpine botanicals. The result is a rich and flavorful walnut liqueur that is not overly sweet, perfect after dinner, in coffee, cream, or egg drinks. In cocktails, Nux Alpina is an extraordinary complement to brown spirits and dark fortified wines, like Madeira, sherry and sweet red vermouth.
