The search for higher levels of quality, time and competitiveness is a constant concern of economic agencies and agro - food could not be different. A growing body of research has been published detailing the use of analytical techniques for determining the mineral content, isotopic ratios or both as geographical descriptors of different agricultural products from fresh food to processed products. A search of wines in Brazil is still very restricted to the poles wine producers in the country. And, most of the work has as objective the analysis of classical parameters of quality control, and recent research in our country involving the development and / or application of methodologies that characterize the wine and its producing region. Spectrometric techniques such as ICP-OES, ICP-MS, are the most used for this purpose and were used in this study. For the first time the study of the isotopic ratios of lead and boron was applied to the Brazilian wines. The analysis and classification of the major components (PCCA) and cluster analysis (CA) were used for data processing. The South and Northeast could be identified using data from both inorganic as the isotopic characterization, but not enough to define the wine producing regions of Rio Grande do Sul, particularly the Valley of the Vineyards. It became clear in this study that the use of multivariate statistical data obtained through the inorganic and isotopic determinations is a powerful analytical tool.
