Siegfried Wonderspritz is the aperitif expression in the brand's Wonder range, made by Rheinland Distillers in Bonn. Unlike the spirit alternatives elsewhere in the range, it is a botanical concentrate designed to dilute: one part Wonderspritz to three parts non-alcoholic sparkling wine, or mineral water and soda over ice with a slice of orange. The botanicals include orange peel, gentian root, and herbs, with no artificial flavours.
