Wine composition of Merlot and Cabernet Sauvignon vine clones under the environmental conditions of Serra Gaúcha, Brazil

Abstract This study aimed to evaluate the wine composition from vine clones of Merlot (181, 346, 347, 348) and Cabernet Sauvignon (R5, 18A, 163, 338, 341).

After crushing and destemming the grapes, the musts were transferred to glass containers, where the alcoholic and later malolactic fermentations occurred. Next, the wines were bottled and analyzed, where the classical variables were determined by physicochemical methods, volatile compounds by gas chromatography, and minerals b...
