The aim of the study was to investigate the impact of the on-vine double maturation raisonnée (DMR) and off-vine berry partial dehydration in the chamber (PDC) on the chemical characteristics of the grape and wine grapevine cultivar 'Refosk'. A liquid chromatography-mass spectrometry (LC-MS) system was used for the identification and quantification of phenolics and the HPLC for sugars and organic acids. Berries subjected to DMR partial dehydration reached technological maturity (18.5 °Brix) within 14 days of cane cutting and those under PDC in 22 days upon harvest. The greatest decline in berry weight was recorded in the PDC treatment (14%), …
