Multivariate classification of wines from seven clones of Monastrell grapes

The enological characteristics of different clones of Monastrell grapes hav e been studied. The wines obtained from different clones were subjected to chemical analyses, including the determination of organic acids, colour cha racteristics and mineral elements. Significant differences were found among clones. To check if these analytical parameters could correctly classify t he wine samples, multivariate statistical analysis was done. Cluster and pr incipal component analysis classified correctly samples belonging to the sa me clone. (C) 2000 Society of Chemical Industry.
