Ranfol or Štajerska Belina, widely known as Gouais Blanc, covers an area of 114.3 ha in Hrvatsko Zagorje.
It is a variety of medium lushness and high yield, which varies from year to year depending on climatic conditions at the time of pollination. It requires elevated and airy positions and a larger vine growing area, as well as cluster thinning.
It ripens in the third period, and its vegetation cycle starts medium late. It gives the best results with mixed pruning that leaves a long fruitful one-year-old wood. It is moderately susceptible to powdery mildew, downy mildew, and Botrytis cinerea (grey mould). The grapes are of below-average quality, especially in conditions of high yield. They are used to produce neutral and light-bodied wines, with a higher level of acidity, suitable for mass production and blending.
