Resumo: The quality of the grapes is changeable and through this study we pretend to analyze the effect of intensity and season of cluster’s thinning (M0 – control, M1 – thinning, leaving one cluster/ talon in buckshot berry season, M2 - thinning, leaving one cluster/talon in verasion season, M3 - thinning, leaving one cluster/stalk in buckshot berry season, M4 - thinning, leaving one cluster/ stalk in verasion season) over leaf area, canopy structure, grape maturation and yield. The thinning consisted on a qualitative cluster removal (two intensities) in two different seasons (buckshot berry and verasion). The essay took place at “Herdade do Rocim”, sub region of Vidigueira in the wine region of Alentejo, in 2011, over the “Aragonês” and the “Alicante Bouschet” varieties. When compared with the witness, the modalities of both varieties in which the thinning was made, presented differences in the yield (number of clusters, average production per plant, total production per hectare) although the M3 and M4 of “Aragonês” only diverged with M0 in the number of clusters. Despite of being less productive, the thinned modalities had a superior probable alcoholic content (PAC). The modalities M3 and M4 presented a better balance between yield and PAC.
