The bud break anticipation would be accompanied by the anticipation of maturation, thus it would be possible to obtain an increase in grape and wine quality. The study aimed to evaluate the effect of different pruning times on phenology and chemical composition of Merlot grapevines. The experiment was conducted at EPAGRI Experimental Station, located in the city of S??o Joaquim, Santa Catarina State (28??17'39? S; 49??55'56? W, altitude 1,415 m a.s.l.), during season 2016. The vineyard was planted in 2006, the plants were grafted on Paulsen 1103, vines were trained in vertical shooting positioning trellis and spacing 3.0 x 1.5 m. The pruning dates were May 29th, June 25th, July 23rd, August 21st, and September 8th (control). The experimental design was randomized blocks with five plants per plot. The phenology was evaluated until inflorescence clearly visible stage. During harvest it was evaluated soluble solids, pH, total acidity and total polyphenols. When pruning is anticipated to the end of May, there is an anticipation in bud break of about a month. There was an increase in the concentration of total polyphenols and berry weight when the vines were pruned on May 29th and July 23rd. The soluble solids and pH were not affected by pruning time, while pruning performed on the first date reduced total acidity.  abud break  aMerlot  aVitis vinifera L1 aBRIGHENTI, A.
