Factor analysis was necessary to interpret the many data coming from the grape maturation study (8 vintages, 14 plots, 6 berry samples per plot and vintage, and 10 berry composition variables for each sample). Three factors were identified as a result of the analysis of the factor loading pattern that were designated as maturation, concentration, and mineral factors, according to their meaning. These factors accounted for 59\% of the variance within the data, enabled the modelling of the maturation process, and showed the influence of climatological and location factors.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/48/3/317}, eprint = {https://www.ajevonline.org/content/48/3/317.full.pdf}, journal = {American Journal of Enology and Viticulture} }
