Abstract

Graševina je rasprostranjena sorta grožđa u svim dijelovima kontinentalne Hrvatske. Ona je naime, gospodarski najvažnija i najraširenija hrvatska sorta vinove loze, te ju isključivo nalazimo u kontinentalnim vinogorjima. Prema službenim podacima i procjeni autoriteta struke, svaki peti trs u hrvatskim vinogradima je Graševina. Dobre je i redovite rodnosti, što je posebno važno naglasiti, jer daje prilično ujednačenu kakvoću. Stoga istoimeno vino po količini proizvodnje, prodaje i konzumacije zauzima vodeće mjesto u Hrvatskoj. U ovom radu provedena je procjena kvalitete i kategorizacija vina Graševina istog proizvođača prije puštanja u promet. Za ispitivanja su odabrani uzorci dva vina Graševina godina proizvodnje 2016. i 2017., iz podregije Podunavlje, Iločko vinogorje. Provedena je fizikalno-kemijska analiza odabranih uzoraka i rezultati su pokazali da oba vina zadovoljavaju propisane zahtjeve. Prema kategorijama kvalitete vino proizvedeno 2016. godine spada u kategoriju kvalitetnih vina, dok vino proizvedeno 2017. godine spada u kategoriju vrhunskih vina.

Abstract (english)

Graševina is a widespread grape variety in all parts of continental Croatia. It is the most important and the most widely used Croatian grape variety and could be exclusively found in continental vineyards. According to official data and estimation of the profession's authority, every fifth vine in Croatian vineyards is Graševina. It has also a good regular birth rate, which is especially important to emphasize because it gives a fairly uniform quality. Therefore, the wine of the same name, by volume of production, sales and consumption takes the lead in Croatia. This paper evaluates the quality and categorization of Graševina wines of the same producer. prior to release on the market. Two samples of Graševina wines, produced in the years 2016 and 2017, from Podunavlje subregion, Ilok vineyard, were examined. Physico-chemical analysis of selected samples was performed and the results showed that both wines meet the prescribed requirements. According to the quality categories, the wine produced in 2016 falls into the category of quality wines, while the wine produced in 2017 falls into the category of top quality wines.
