'Negro Amaro' and 'Primitivo' are cultivars of southern Italy, designated for the production of red wines. They were introduced in Montenegro in 2003. Examinations were performed during the period 2007-2009 in the vineyard located at Cemovsko field. What has been observed is the length and width of the cluster and berries, cluster weight, yield of grape, contents of sugar and acid in the must as well as the quality of wine that is made by microvinification. The highest yield of grape per vine was found in 'Vranac' (1.72 kg/vine), while the highest amount of sugar was in 'Negro Amaro' (24%). Wine that was made from 'Vranac' turned out to be the best among these wines. The highest contents of extracts, polyphenols, and anthocyanins were found in the wine of the 'Vranac' cultivar, while the lowest was in the wine of 'Primitivo'. 收起
