Abstract:
Meteorological data of the Franciacorta AOC are were collected since 1966 by 4 different weather
station placed in the same number of sites, selected with the aim of giving data representative of
the whole AOC territory: those data were daily collected and concerned temperature (minimum and
maximum), relative humidity and rainfalls. Since 2001 a large number of Chardonnay vineyards
were monitored in order to study ripening kinetics (from veraison to harvest) by the measure of
soluble solids, pH, titratable acidity, malic and tartaric acid. These data set was the starting point of
this research, wich has the purpose of seeking for relationships between meteorological data,
agronomical variables and productive parameters; furthermore, an improved knowledgeon the
viticoltural model, object of this study, and on the source of variability that determine different level
of production (both from a quality and quantity point of view) was searched. Besides, through a
mechanistic approach, a model simulating sugars store during ripening was development and
tested using daily meteorological data (minimum and maximum temperature and rainfalls) as
guiding variables.
