Characteristics of Petit verdot grape variety (Vitis vinifera L.) grown in Tikveš vineyards

Research is being performed to the variety of Petit verdot. The vineyards are sited on the Lepovo-Tikveš vineyards, in the property of Bovin winery. Plantation is started in 2008 with certified plantation material, 2.4 m planting distance between rows, and 1.0 m distance between vines in a row. The training system is Guyot two arms, with 20 eyelets leaving the vine. Some optimal agro-technical and ampelo-technical measures are applied. The plantation is under drip irrigation system. During the research period (2011– 2012) the following items were included: yield (kg/vine), chemical composition of grape must (sugar, total acid, pH), and chemical analysis of wine. The results show considerable variation in yield interest (14.48), which is due to the age of the crop, whether it is in the second (2011) or in the third (2012) year of birth. The must contains 230 g/L sugar and 5.5 g/L total acids, average for the test period. The wine has a high content of extract (40 g/L) and 13.11% vol alcohol, which is due to selective grape harvesting and the way of vinification (winemaking)

Characteristics of Sangiovese grape variety (Vitis vinifera L.) grown in Tikveš vineyards

Studies were carried out to the variety Sangiovese of manufacturing plants located in the site Lepovo-Tikveš vineyards and all of this in property of the Bovin Winery. During the period of study (2011-2012 year) the following items were included: realized yields (kg/vine), chemical composition of grape must (sugar content, total acids, pH) and chemical analysis of wine. The results show considerable variation in yield (coefficient of variation was 18.45) which is due to the age of the crop or it is in the second (2011) and third (2012) year of birth. The must contains 224 g/L sugar and 6.75 g/l total acids average for the test period. The wine has a high content of extract (33 g/L) and alcohol from 12.90 vol% which is due to selective harvesting of grapes and the way of vinification
