Abstract
The fourth agricultural revolution is leading us into a time of using data science as a
tool to implement precision viticulture. Infrared spectroscopy provides the means for
rapid and large-scale data collection to achieve this goal. The non-invasive applications
of infrared spectroscopy in grapevines are still in its infancy, but recent studies have
reported its feasibility. This review examines near infrared and mid infrared spectroscopy
for the qualitative and quantitative investigation of intact grapevine organs. Qualitative
applications, with the focus on using spectral data for categorization purposes, is
discussed. The quantitative applications discussed in this review focuses on the
methods associated with carbohydrates, nitrogen, and amino acids, using both invasive
and non-invasive means of sample measurement. Few studies have investigated the
use of infrared spectroscopy for the direct measurement of intact, fresh, and unfrozen
grapevine organs such as berries or leaves, and these studies are examined in
depth. The chemometric procedures associated with qualitative and quantitative infrared
techniques are discussed, followed by the critical evaluation of the future prospects that
could be expected in the field.
