Research on viticulturally techniques has gained attention for the impact they have in the composition and quality of grapes and wines. This work evaluate the effect of pruning thinning on the viticulturally parameters of Bobal red variety. Four pruning treatments which included winter pruning and green pruning activities were studied. Viticulturally parameters such as vigor, vine balance, cluster characteristics and yield were evaluated.

The treatments showed different results in viticulturally and physicochemical parameters. Vigor and berry size decreased with a larger pruning. Vine balance was best for the control. The control also had better phenolic maturity when compared with the rest of the treatments, and thinning showed to improve maturity parameters. Yield was higher for the larger pruning.
