- •
SDI strategy improved technological berry quality and financial efficiency, to the detriment of WUEyield, berry and wine polyphenolic content.
- •
DI strategies (PRI and RDI) increased WUEyield, berry polyphenolic content and wine quality, but at the expense of lower financial efficiency.
- •
The response to PRI depended on the volume of water applied in the wet root zone and the soil total water availability.
- •
PRI-1 improved the long-term yield-quality-WUE response and berry anthocyanin content and was also the most economically profitable.
- •
We identified an optimum irrigation water volume range (134–200 mm year−1) and an optimum range of yield (8000–12,000 kg ha−1) in DI Monastrell vineyards.
