Resumo: This work aims to study the evolution of the various characteristics of wine, using with samples from vineyards in the region of the São Francisco Valley, Brazil that are in different states of maturation. Samples were taken from four different plots that were pruned at different dates, from Cabernet Sauvignon, Aragonez and Alicante Bouschet varieties. Before analyzing the samples, two different types of analysis were evaluated concerning the precursors of aromas, tannins and anthocyanins levels of total phenolic contents. At the end the Carbonneau method was chosen for the extraction of compounds and in order to study them after. To complement the analysis of each sample the following characteristics were also analyzed: sugars, malic acid, tartaric acid and total acidity. The study shows that many of the changes in the evolution of aging are due to the weather, and that the greater the degree of maturity the further the weather is an interfering factor. We must also bear in mind that the plots had differences in viticultural practices, and it was demonstrated that driving systems, clones and rootstocks also interfere with the results of the samples
