Abstract

During the 2008 growing season field tests have been carried out on three varieties of wine grape. Over 2500 samples of wine grape berries were scanned with a portable and commercial near infrared (NIR) spectrometer and subsequently processed to determine °Brix using a digital refractometer. The main objectives of this research are to evalúate the potential of a portable NIR equipment to measure the changes in soluble solid contents of grapes during the pre-harvest period, and to establish calibration model for soluble solid contení (°Brix) in grapes, in order to provide a non destructive tool for determining optimal harvest date. A first calibration model has been constructed based on data of three varieties with a R2 of 0.81.
