The three most important wine types in Croatia are : Istrian Malvasia, Plavac and Riesling with a total representation makes 48,09 %, while the remaining 51,91 % are other types. One of these other types is yellow muscat, that belong to group of of muscat types. Yellow muscat has high resistance to botrytis (grey mould) but it is susceptible to black ticking. Common characteristic of all muscat types is very highlighted grape aroma. Quantity of aromatic elements ingrapes depends of number of factors like climate, soil, degree of maturity of the grapes etc. Climate is avarage balance of weather on some teritory in some time interval and into consideration is taken avarage and extreme deviations. Research goals are to compare by physical-chemical analysis two wine samples from 2012. And 2013. Year and come to conclusion which are the differences and name the causes of thats differences. Reasearch is conducted on Yellow Muscat type wines produced in winery at University of Požega. Physical-chemical analysis is objective methode of evalvating the wines and it is perform to determine phiscaly-chemical composition of the wine, its health condition quantitative ratio of individual ingredients etc.
