Abstract: The quality of a wine is directly linked to the best point of the grape maturation. Harvest accomplished in premature or late time result in wines with smaller expression of their qualitative potentials. The objective of this work was to evaluate the evolution of the maturation of the fruits and the composition of the musts of Cabernet Sauvignon and Merlot varieties in five different commercial vineyards of São Joaquim’s area, during the cycles of 2010 to 2013. All technological maturation and polyphenolic indicators of the grapes presented an appropriate evolution of the parameters and they were shown appropriate for the elaboration of fine high quality wines. However, the conditions of the area allow a slow decline of the organic acid levels in the grapes and musts without, however, endanger the balance between sugar and acidity. After the crop, the musts presented attributes that prove the good qualitative potential of the varieties studied in relation to the present conditions in the area.
