Syrah as a variety in Croatian vineyards has appeared only recently, although it is known and recognized in the world, it is expected to achieve the best results. Wine quality depends on many factors, but climatic conditions are the most important end product indicator. Climatic conditions vary from year to year, which controls and effect the quality of grape and wine as its product. A four-year study was conducted on Syrah cultivars on the production areas of the Kutjevo vineyard, owned by the Polytechnic of Požega, during 2011- 2014. years. After collected results and analysis, it was established that 2012 was the most favorable for Syrah's properties. The highest amount of average sunshine hours, the temperature during the vegetation period, caused that the grapes of that year accumulated the highest amounts of sugar, resulting in the highest percentage of alcohol in wine compared to other years. The vintage year 2012 after the wine analysis gave the best results with respect to the vintage date, the wine of that year achieved the highest rating by the organoleptic commission. Vintage year 2014 was adverse to its properties; overcrowding, small amounts of sunshine and low temperatures caused the grapes of that year to accumulate the least amount of sugar, resulting in a low percentage of alcohol in wine after chemical analysis and a relatively low rating by the Organoleptic Evaluation Commission.
