The region of viticultural production near Pinto Bandeira, Brazil, is being studied to define typical characteristics of wines locally produced. Vineyards above altitudes of 500m qualify as “Mountain Wines”, a geographical denomination. Rocks, soils, and wines are analyzed. Several techniques are used: remote sensing, radiometry, and chemical analysis. Results indicate that elements (Fe, Cu, Mg, Al, and others) from rocks and soils are not detected in wines. However, minerals present in rocks and soils (montmorillonite, mordenite, illite) can be traced in wines, indicating a transmission of soils descriptors to wines. Geological maps of the region were generated from images of SPOT, Landsat and ASTER satellites.
