摘要: The aim of this work was to evaluate plastic overhead covering (POC) influence on must and wine Moscato Giallo cultivar. In two harvests the 2006 2007 vintages an experiment carry out in a completely randomized design. It performed vineyard covered with impermeable cloth without as control. From each vineyard, three microvinification (20 L) were elaborated. Physico-chemical analysis musts (oBrix, reduce sugar content, density, total acidity, tartaric acid, malic acid e pH) wines (density, alcohol degree, volatile pH, dry extract, ashes, I 420, compounds minerals) analyzed. According results POC (raffia type 160 µm) grapes showed more yield must. However due delay maturation lower concentration. Wine produced had graduation. Another hand, better sanity resulted tenors ethyl acetate acidity. system demands harvest achieve same concentration graduation compared from open sky.
