Influence of co-winemaking technique in sensory characteristics of new Spanish red wines

The influence of co-winemaking technique on the sensory profile of wines made from minority red grape varieties cultivated in La Mancha region (Spain) was researched by sensory characterization. Sensory analysis was carried out by a panel of 15 experienced wine-testers, all with a previous training. The sensory profiles of monovarietal red wines-Cencibel, Bobal and Moravia Agria-were studied and also the effects of co-winemaking technique on sensory characteristics were evaluated. Co-winemaking red wines were obtained by blending (a) Cencibel (50%) + Bobal (50%); (b) Cencibel (50%) + Moravía Agria (50%) and (c) the three grape varieties Cencibel (33%) + Bobal (33%) + Moravía Agria (33%). The co-winemaking technique intensified the principal sensory properties of monovarietal wines and the wines proved to be more complex than the monovarietal wines.
