The University of Castilla-La Mancha, within the frame of FENAVIN-2009, has organized the workshop "Innovation as a strategy of differentiation: from biotechnology to commercialization of wine", first session of which has been based on "The importance of the terroir in the elaboration of wine", in which Luigi Bavaresco, Professor of the Catholic University Sacro Cuore of Piacenza (Italy) has participated; along with José Ángel Amorós Ortiz-Villajos, Professor of the University of Castilla-La Mancha and Francisco Montero Riquelme, Professor of the University of Castilla-La Mancha.
Luigi Bavaresco has focused his explanation on the role that climate has in wine growing. In the first place, he has given the audience a general view of grape production in the world, which with regards to production of fruit holds the second place, after bananas. 49% of grape production takes place in Europe and 70% of the grapes are used to make wine. He likewise pointed out that global distribution of wine growing is to be found in Spain, while the average production is focused in Italy.
The Italian professor has enumerated the factors that are responsible for production and the quality of the grapes, which reside in the soil and climate, elements that make up the concept of terroir. He also commented that the role of the vine grower is important, because "the vine grower is the one capable of recognizing the quality of the territory and exploiting its qualities".
According to Bavaresco, climate is characterized by light and temperature. In this sense he highlighted that equally important are the meteorological aspects, "thus the reason why we have good and bad harvests". He reminded that temperature is the most important climate factor that affects the choice of variety.
The speaker underlined that the world is confronting a tremendous problem: the climate change. The consequences of the climate change are focused on the increase in temperature, which has a profound impact on the agricultural systems. In short, according to the professor the main effects are focused on the advancement of the harvest and that grapes have more sugar and less acidity.
He finally suggested how the vine should be adapted to the climate. In this respect he pointed out that the variety of the grape can be changed; rootstocks that support drought better can be used and vines can be sprayed with anti-stress production products.
On his part, the professor of the University of Castilla-La Mancha José Angel Amorós has centered his speech on the viniculture agri-system that is composed by the following factors: soil, plant, climate and cultural practices. "It is impossible to conceive a terroir without the intervention of man", he stressed.
Amorós has defined the soil as the "terroir's poor relative" because making the influence of the soil on wine manifest is very difficult". During his speech he detailed the different types of soils that exist and their physical properties, amongst which the gross elements are to be highlighted, color, texture, clay and organic matter.
Finally, Francisco Montero's intervention has been based on the quality of wine production. He has emphasized that "we must be more aware of reality. We must be realistic and evaluate the possibilities we have to achieve this quality". The professor of the University of Castilla-La Mancha has pointed out that "Castilla-La Mancha is a region of contrasts in which all the hybrid resources are limited (soil, water and vegetation)".
