• Spectroscopic techniques such as near infrared (NIR) can be used as a physiological indicator for irrigation scheduling based on vine water demand, rather than relying on weather and/or soil moisture measurements, which do not consider the plant in the assessment
  • NIR can be used to analyze chlorophyll in grape wine leaves, sugar content, nutrients and carbohydrates
  • The use of NIR has been reported as a tool to measure physical properties such as firmness, elasticity, and touch resistance in batches of Cabernet Franc grapes (LeMoigne n = 84 et al., 2008)
  • The method based on NIR spectroscopy has been used to discriminate ripening, parcel effects, predict ripening stages, and parcel type (LeMoigne et al., 2008)
  • Investigations of whole grape berry presentation using a NIR spectroscopic device indicated that NIR may have potential for use at the weighbridge or for in -field analysis of total anthocyanins (color), TSS and pH (Cozzolino et al.,2004)
  • Studies have revealed the potential of NIR spectroscopy to predict the concentration of and monitor the extraction and evolution of phenolic compounds during red wine fermentation (Cozzolino et al., 2006)
