Siegfried Wylda is the functional entry in Rheinland Distillers' range, distinct from the Wonderleaf series in both formulation and intent. Built around six adaptogenic botanicals, maca, schisandra, ginseng, damiana, matcha, and moringa, it also provides vitamin B6 and magnesium. The caffeine content is 128mg per 100ml, drawn from the matcha in the blend. Wylda is designed to be served as a long drink, mixed 1:3 with tonic water, and contains no sugar or sweeteners.
