•The WUEi can be used as selection criteria to improve WUE in grapevines.•There is a wide variability of the WUEi among grapevine cultivars.•Inside clones of Tempranillo the WUEi variability is around 80% than among cultivars.•Some cultivars and clones with higher and lower WUEi than the average wer...
