characterization of a new wine terroir unit in south Brazil are reported.Presently,several areas in Brazil are being studied,in an effort to define new wine terroirsand improve the quality of Brazilian wines.This paper reports what is being done,byEmbrapa(Brazilian Agricultural Research Corporation)and its partners Remote Sensing andMeteorological Research Center(CEPSRMUFRGS)and Brazilian Geological Survey(CPRM),in the Encruzilhada do Sul region,at Rio Grande do Sul State,that is part of theSerra do Sudeste viticultural region.Satellite images from several sources(SRTM,ASTER,ALOS)were used,together with field data(rock samples).Digital elevation models were builtand used to define areas with slopes and solar expositions adequate to vine growing,withalcitudes above 350m.Spectroradiometry of rock samples was perfomed,to identify severalminerals(montmorilonite,illite,pyTophilite and kaolinite).Geologic maps were used to locaterock types to collected in field uips;those rocks had their spectral response extracted fromradiometry,and fitted to the six bands of ASTER SWIR subsystem,resulting in a map of thedistribution of these rocks in some areas of interest.Two wineries were more closely studiedThe first arez produces wine from 35 hectares of Cabermet Szuvignon,Merlot,Nebbiolo,Pinot Noir and Chardonnay.The other winery has 61 hectares and produces Pinot Noir andChardonnay grapes for sparkling wines.The study concludes that the use of remote sensingresources and associated geotechnologies are effective to terToir studies.  \n##

viticulturalgeographic appellations,and for this effort,geotechnologies have been used by Embrapa andEmbrapa Grape and Wine Research Center(Centro Nacional de Pesquisas em Uva e  \nVIII INTERNATIONALTERROIR CONGRESS  \nVinho/CNPUV)is located in Bento Goncalves,at Rio Grande do Sul State,at the mainBrazilian wine production region.One of the more promising new studied areas is locatednear Encruzilhada do Sul city,in Serra do Sudeste viticultural region (Figure 1).This area isdominated by extensive grasslands with minor forest patches developed over old Precambriantenains represented mainly by granitic-gnaissic rocks.Soils are mainly cambisolos andargisolos,poor in organic marter,well drained and occasionally gravely.The whole region ispart of the Pampa Biome (Embrapa 2008),which also covers large areas in neighboringUnuguay and Argentina.  \nFigure 1.Location and vineyards in Encruzilhada do Sul,Brazil  \nVineyards for fine wines(Vinis vinifera)were first introduced around 1970,and presentlythere are more than 300 hectares with grapes such as Barbera,Cabermet Franc,CabernetSauvignon,Merlot,Periquita,Teroldego,Marselan,Pinot Noir,Ancelota,Malbec,TourigaNacional,Gamay,Arinamoa,Alicante Bouschet,Chardonnay.Gewirztaminer,Malvasia deCindia,Sauvignon Blanc,Riesling,and others.Such a large diversity of vineyards proves anongoing search for grape varieties that leads to a terToir identity.This identity,in fact,isalready suggested by Cemin and Ducati(2008),which detected spectral
