Geologia integrada a dados de relevo para caracterização de terroir vitivinícola em Pinheiro Machado, Brasil

Abstract

Wine terroir characterizes an area in which natural and cultural factors determine the typicality of wines. Worldwide emblematic examples relate wine terroir with rocks, as in Burgundy, Canary Islands, Azores, Douro Valley, South Africa, California, among others. In the state of Rio Grande do Sul, the largest wine producer in Brazil, the Serra Gaúcha wine region is known by many geographical appellation, such as Vale dos Vinhedos. In addition this fact, there are new wine growing areas in the southern region, such as Campanha and Serra do Sudeste wine regions. Brazilian Agriculture Research Corporation has made studies using geotechnology in the Serra do Sudeste Wine Region and studies was made with geology and wine. The objective of this study was to investigate aspects of the relief in each geological unit, in order to evaluate its favorability for wine terroir under relief aspects. Using MDE, elevation, slope and exposure were obtained and these were reclassified and analyzed in GIS. The integration of geological data with relief information resulted in geological criteria for wine terroir in the Pinheiro Machado Region. The product of this work was the indication of areas that have relief attributes favorable to the viticulture in each lithology unit and its capacity to contribute for wine terroir in Brazil
