The Rothenpfad is the geological oddball of Clemens Busch’s lineup. It sits on a vein of iron- and copper-rich red slate that surfaces in only a handful of famous Mosel sites before ending right here in Punderich. That red slate gives this bone-dry Grosses Gewachs Riesling a distinct personality: more spice, more savory depth, a slightly warmer-feeling core than its gray-slate siblings. Farmed biodynamically from old, ungrafted vines, it’s powerful yet precise, with a finish that just keeps going. One for anyone who wants to taste how dramatically a single vineyard’s stone can shape a wine.
