Front-face fluorescence excitation-emission matrices in combination with three-way chemometrics for the discrimination and prediction of phenolic response to vineyard agronomic practices

•PARAFAC, LDA and DA-UPLS discriminated between irrigated and non-irrigated grapes.•PARAFAC, LDA and DA-UPLS discriminated between high and low crop load.•The resveratrol concentration predictions were better applying UPLS.•The PARAFAC results for catechin and epicatechin were comparable with LC res...
