Microzoning is the main arrangement to exploit positive and mitigate negative climate influences at vine growing. A winegrowing region with tradicional viticulture and with characteristic climate conditions is called terroir. We have defined the climate conditions and their indexes for the Goriska brda winegrowing region in years 2000 and 2001. Average values of heliothermic coefficient according Huglin (2457), sum of effective air temperature according Winkler (4002), heliothermic coefficient according Branas (5.9), thermic coefficient according Kerner (11.9), hydrothermic coefficient according Seljaninov (2.0) and bioclimat index (3.0) substantiate a suitability of vine growing in Brda. Brda is momentarily divided into 16 winegrowing areas and 2 winegrowing positions. We propose a distribution at the most of 4 winegrowing areas, namely Dobrovo, Neblo, Vipolze and Ceglo-Kojsko. We have to determine the optimal vine cultivation for each cultivar according separate winegrowing area. Our results confirm that Goriska brda is a terroir.
