Abstract
In Sannio Beneventano viticulture dates back to Roman times and is still an important economic sector in this province. This work correlates wine production to its origin and its articulate environmental and geological peculiarities. We analysed 109 samples for 35 different parameters (trace metal, sulphur dioxide and acids) and analytical data were treated with statistical methods. Factors arising from traditional treatments operated on crops or from local pollutant emissions have proved to be spread on products regardless of their specific origin. Multivariate statistics analysis has confirmed that, in particular, the natural geological trace metal composition can be used to characterize the product and act as a finger print to the raw materials geographic origin.
