Abstract

The purpose of the present work was to assess the influence of water stress and cover cropping on the phenolic fraction of Aglianico and Nero di Troia grapes and wines, produced in 2007 and 2008 in Apulia region, Italy. Two parcels with soil tillage and cover crop, using Festuca rubra, Festuca ovina and Trifolium subterraneum, were considered. Each of the two parcels was divided into three sub parcels, and each one was subjected to different irrigation volumes corresponding to 36%, 24% and 0% of crop evapotranspiration, respectively. Grapes were submitted to traditional red winemaking using 5 days maceration, without any other oenological treatments. Results showed that the content of some phenols is strongly influenced by the season and water deficit, and partly by soil management. Water stress together with soil tillage led to an increased of phenolic compounds in grapes and, consequently, in wines, suggesting that the use of these agronomic practices could improve the oenological potential of the two cultivars grown in Apulia.
