Study of the Chianti and Chianti Classico appellations: Evaluation of enological potential of Sangiovese and complementary varieties by a multiparametric approach

This PhD program was developed in collaboration between the Ruffino winery and the University of Bologna and the University of Belgrade. All the work is divided in three sections as follows: The first part is related to the climate change in Tuscany. The ongoing climate change may affect the agriculture to a large extent since all the crop production is influenced by the weather conditions. Thus, even viticulture and wine production may subject to certain changes. The new meteorological conditions may have a strong impact to the DOP wine production that follows their appropriate production regulations. This is the reason why it is important to better understand the climate conditions of the last century and to estimate the future climate conditions in order to be able to adapt the wine production to the newly formed environment, keeping the same wine DOP style and quality characteristics. In this work, the climate conditions in Tuscany where assessed from 1990 until future 2100 year. When it comes to the second part, the typicity and quality of the Chianti and the Chianti Classico appellation of origin were studied. The main grape variety used for these wines is Sangiovese which is employed in at least 75% of the total production of the mentioned wines and it was studied by a multiparametric approach in this PhD research. As for the third part, the wine oxidation, as one of the most important chemical reactions that influences the wine quality and aging, was studied. Polyphenols are one of the main substrates of the wine oxidation and their content was assessed using the linear sweep voltammetry in the initial part of vinification.
