Vernaccia of San Gimignano, a wine which is born “clean”

The first stage of the project entrusted by the Consortium Consorzio della Denominazione San Gimignano to Indaco2 ended. Indaco2 is the spin-off company of the University of Siena (Tuscany) that carries out this study in order to find out how much CO2 is currently emitted in the production cycle of a bottle of Vernaccia of San Gimignano, so taking into account the whole chain, from cultivation of the vineyard, wine-making in the wine cellar, until the bottling of the finished wine. Carbon Footprint is the indicator chosen in order to determine the potential impacts of the life cycle and identify policies to mitigate and counterbalance these impacts.
The response has been very positive, especially considering that this study concerns the actual situation, which is therefore prior to the implementation of possible corrections to the production cycle. The average amount of the emissions generated by the production of a bottle of Vernaccia of San Gimignano resulted to be 0.90 kg of CO2 equivalent. This is a very good result, well below the average obtained from a sample of white wines monitored in Italy.
The project has involved four pilot companies, selected in the territory as representative of the production situation of San Gimignano. One of these companies is the largest one as for both land ​​planted with vines and production, while the other three are characterized by small to medium size, including two biological ones.
The analysis carried out by the team of Indaco2 showed in detail the effects of the different production stages and thus allowed to identify for a certainty a number of possible solutions in order to further reduce the impact of these productions.
