Résumé
Anthocyanins in skins of Tempranillo [Valdepeñas (California)], Moristel, and Garnacha (Grenache) skin grape varieties were separated and quantified by HPLC in two different vintages (1987 and 1988). The relationship between this evolution and the climatology data for the sampled vineyards was studied. The changes in the anthocyanin content were greater between the same varieties in different years than the different varieties in the same year. Nevertheless, differences were found between varieties. The delphinidin- and petunidin-3-glucosides were found in much higher relative content in Tempranillo grapes than in Garnacha and Moristel. Garnacha presents a higher relative content in cyanidin- and peonidin-3-glucosides, while Moristel presents higher malvidin-3-glucoside relative content.
