Manseng is one of our great success stories with Alternative Varieties, its small berries, tough skins & open bunches make it very resistant to botrytis, the bane of our high summer rainfall. Petit Manseng or Gros Manseng? While we believed we planted Petit Manseng fifteen years ago the new DNA research conducted by Wine Australia showed that all planting material that has been imported to Australia is actually Gros Manseng. Whatever Petit or Gros, our Manseng delivers juicy, fresh with unmistakable tension and high flavour concentration resulting in very long aging potential.
