Impact cv. Regent on the chemical composition and quality of wine blended with cv. Pinot noir

V letu 2008 smo na Univerzitetnem centru za vinogradništvo in vinarstvo Meranovo Fakultete za kmetijstvo in biosistemske vede v Mariboru izvedli tipizacijo vin Modri pinot in Regent. Ugotavljali smo vpliv cv. Regent na kemijsko sestavo in kakovost vina v zvrsteh s cv. Modri pinot. Za poskus smo uporabili vina letnika 2007 in pripravili zvrsti iz sortno čistih vin Modri pinot ter Regent. Nato smo tako pri vsakem posameznem vinu kot tudi pri zvrsteh izmerili in proučili vsebnost skupnih titracijskih kislin, pH, skupnih fenolov, taninov, antocianov in barve. Poleg kemične analize, je bila izvedena še senzorična ocena vin. Pri kemijski analizi obravnavanih vzorcev smo ugotovili, da je dodatek Regenta v zvrsti z Modrim pinotom vplival na vse izmerjene kemične parametre, razen na skupne titracijske kisline. Pri senzorični analizi, pa dodatek Regenta k Modremu pinotu vpliva statistično značilno na vonj, zato je potrebno biti pazljiv, da ga ne dodamo preveč. V zvrsteh pa Regent pozitivno vpliva na barvo.In the year 2008, we have at the University centre for Viticulture and Enology Meranovo Faculty of Agriculture and Life Sciences in Maribor, performed a blending of wines Pinot noir and Regent. Our goal was to determined the impact of Regent on the chemical composition and quality of wine in blended wines with Pinot noir. We have used wines of 2007 wintage for the experimet and prepared blended wines from Pinot noir and Regent. In the blended wines we measeured total acidity, pH, total phenols, tannins, antocyanins and colour. Sensory evaluation of wines was carried out beside the chemical analysis. In the chemical analysis of the presented samples, we found that added Regent to Pinot noir has influenced all measured chemical parameters, except the total acicity. In sensory analysis the added Regent to Pinot noir has influenced the smell, so one should be careful with adding it. In all sorts the Regent has positive influence on colour
