Abstract
Graševina bijela najzastupljenija je sorta vinove loze u hrvatskim vinogorjima. Zbog njene važnosti i raznolikosti stilova vina koje može dati, 2004. godine započeo je proces klonske selekcije koji je rezultirao registracijom četiri klona sorte ´Graševine´. Kako bi se analizirao kemijski sastav i kakvoća vina od klonova OB-445 i OB-412, provedena je fermentacija s dva soja Saccharomyces cerevisiae kvascem te sekvencijalna fermentacija s vrstama Metschnikowia pulcherrima i S. cerevisiae. Osnovnom analizom mošta i vina utvrđena je niža koncentracija alkohola u vinu s provedenom sekvencijalnom inokulacijom, ukupna kiselost je istovremeno bila niža, a ukupni fenoli su varirali ovisno o klonu. Senzornim ocjenjivanjem, prema opisnoj i metodi redoslijeda bolje su ocijenjeni uzorci inokulirani sojevima S. cerevisiae.
Abstract (english)
Graševina is the most planted grape variety in Croatia. The range of wine styles produced by this variety is wide. Due to its importance, the process of clonal selection of Graševina began in 2004, after which the four best clones were selected. To test the chemical composition and quality of the wine, clones OB-445 and OB-412 were fermented with two strains of Saccharomyces cerevisiae yeast and sequentially fermented with Metschnikowia pulcherrima and S. cerevisiae strains. According to the basic chemical analysis of must and wine, a decrease in alcohol content was found in wine produced by sequential inoculation, total acids decreased and total phenols varied between samples regarding the used clone. On the other hand, samples inoculated with Saccharomyces sp. were sensory evaluated as better according the general impression and the ranking method.
