Evaluation of the quality wine Riesling

Abstract

Graševina je najzastupljenija sorta grožđa u kontinentalnoj regiji Hrvatske. Srednje je bujna, dobre oplodnje, redovitoga i dobrog prinosa. Kakvoća joj znatno varira ovisno o ekološkim uvjetima i opterećenju. Relativno kasno dozrijeva, otporna je na niske zimske temperature. Sorta graševina je popularna i kod malih proizvođača vina. Stoga je cilj ovoga rada bio procijeniti kakvoću vina graševina proizvedenog na području Vinogorja Petrinja. Istraženi su slijedeći pokazatelji kakvoće vina: relativna gustoća, pH, količina šećera, ukupnih kiselina, pepela, alkalitet pepela i količina fosfora.Riesling is most common sort of grape in continental region of Croatia.
