Background: The effects of cluster thinning (TH) on Verdejo wine composition were studied. Cluster thinning was applied in three water regimes (WR) (R0, rainfed control; R25, drip-irrigated at 25% ETo, and R50, drip-irrigated at 50% ETo) during the 2012-2014 seasons.
Results: Cluster thinning advanced grape maturity, although this was only significant in 2012.
