Cv. 'Melot' and 'Cabarnet Sauvignon' are most widely spread red vine cultivars, grown on all continents. Both cultivars spread over the world simultaneously despite of their differences in amphelographic characteristics and agro-technical demands. The cultivars were probably introduced to Slovenia and Primorska winegrowing region respectively, where they represent two of the most important red cultivars, at the end of 19th century. In Goriska brda the two cultivars are widespread over the whole winegrowing district despite of the fact that quality differences between locations indicate that some geographical positions are not suitable for growing of red wine cultivars. From the quantitative aspect, the most grapes from this two cultivars are produced in location Biljana, Cerovo and Neblo. In the location Kozana the most quality grapes of both cultivars are produced meanwhile on the location Kozbana the quality of produced grapes in the lowest. The cause for the big variability between locations and between years in the quality of grapes in the Goriska brda winegrowing district is in the interaction of weather conditions, agitation of the relief and traditional growing manner which isn't suitable for high quality of grapes.
