| description | The modern enology technology allows the elaboration of high quality wines that preserve the differentiating characteristics according to the vine, production area, fermentative yeasts or to the different technology used for the elaboration of wine.
The study of 45 spanish white wines with « Denomination of Origin », 5 of those belong to Alto Turia, 6 to the Clariano, 14 to the Valentino, 10 to the Valdepeñas and 10 to the Rueda, allows to establish importants differences among them according to their chemical composition. This differentiation has been possible by means of the application of the Discriminant Analysis to 35 parameters related with the chemical composition of theses wines. In the first place these compounds have been grouped, according to their chemical affinity, in three groups: general component, alcohols and esters. Discriminant Analysis has been applied to each one of these groups, being observed that the esters allow to be carried out the classification of these wines in their corresponding groups, because only it confuses some wine of Clariano with those of Valentino.
To carry out a correct classification of 45 wines studied in their corresponding « Denomination of Origin », it is necessary to appeal to carry out a Discriminant Analysis with the 35 compounds together, being, in this case, the compounds that contribute to this differentiation pratically the same ones that those which contribued to differentiate each group of variables separately. |
