Study of changes organic acids in red wines during malolactic fermentation
Original language description
The aim of this contribution is to be able to describe the movement of organic acids in red wine during malolactic fermentation. Wines from Znojmo wine region were represented by varieties of Svatovavřinecké (Saint Laurent), Rulandské modré (Pinot Noir),Zweigeltrebe, Frankovka (Lemberger) and Dornfelder. The grapes went through the same way of wine making and after completion of alcoholic fermentation were inoculated with pure culture of lactic acid bacteria Oenococcus oeni. Samples were taken for chemical analysis during biodegradation of acids within the range of 2 to 4 days and they were measured using a device WineScan FT 120. Chemical analysis detected changes in the concentrations of the following parameters: total acidity, lactic, malic, tartaric and citric acids. The total content of acids statistically significantly (P = 0.05) differed only between samples of Svatovavřinecké T 66 and Zweigeltrebe T 2. The differences of average mass concentrations of lactic, malic and citric
