This article shares data and field observations along with scientific findings to discuss the effect of irrigation frequency on vineyard water use regulation. It is suggested that imposing high irrigation frequency is not always the most desirable strategy to reduce water deficit. High frequency irrigation can lead to more severe yield loss and increase sugar concentration before harvest due to fruit ripening disorders or heightened fruit sensitivity to shriveling. Such fruit responses related to water deficit management should be avoided particularly in a context of higher temperatures. The discussion leverages historical vineyard performances using continuous vine water status measurements in response to high irrigation frequency. Thanks...
