Abstract
An investigation was undertaken to prepare wines from the pure and blended juices of Sauvignon Blanc (SB) and Manjari Naveen (MN) grapes. Juices were blended according to plan, and wines were prepared following the standard vinification procedure and evaluated after two rackings. Alcohol in prepared wines ranged from 11.48 to 12.75 per cent. The acidity, volatile acidity, and pH of wines were within acceptable limits. Observed aroma compounds using ‘GC×GC-TOF/MS’ were mainly related to aroma notes in commercial wines. Wine prepared from T7 (SB-50% + MN 50%) attained a maximum score (4.7 out of 5 points hedonic scale) in overall acceptability. The wine quality got improved when the juices of Sauvignon Blanc and Manjari Naveen were blended before fermentation. However, there is a need to optimize crop load, suitable rootstock, maturity level at harvest, etc., for harnessing the aromatic nature by adopting a suitable juice combination of these two varieties.
