With the aim of studying the influence of the late pruning technique in mitigating grape ripening imbalances, a field trial was carried out during three vintages on cv. Monastrell in a semi–arid climate where the effects of two late pruning strategies carried out in spring were compared to a conventional winter pruning. The late pruning delayed grape harvest time by about a week. In the third year of testing, late pruning resulted in a decrease in production, mainly linked to the decrease in the average cluster weight. With the same total solids values, grapes from the latest pruning (carried out 10 days after the buds began to sprout) had lower pH than those from the other treatments, which will affect wine microbiological stability during fermentation. In the wines, late pruning reduced alcohol content, total acidity, malic acid and color parameters with respect to the conventionally pruned wines. Consequently, late pruning is a promising technique to delay the phenological cycle in semi–arid climates and reduce the alcohol content of wines; however, more studies are needed to assess its impact on the wine phenolic composition.
