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.Graševina is a widespread grape variety in all parts of continental Croatia.
