Completer

Completer or Malanstraube is a white Swiss wine grape variety grown primarily in eastern Switzerland around Graubünden. The Completer vine was once domesticated but has now become mostly feral though some Swiss winemakers will make limited quantities of wine harvested from the wild vines. Wine produced from Completer tends to be very full bodied and aromatic.
