This region cultivares about 35 thousand hectares and produces more than 500thousand tons of grapes, most of them processed for wine and grape juice produc-tion. Serra Gaúcha is a moumainous region wirh a somewhat mild climate duringthe four seasons of the year, which is an invitarion [O the enorourism. Indeed, thou-sands of people tasre wines especially during the winter and summer times. Wineand grape juices are made following rradinonal methods. However, due to the in-creasing dernand for foods produced according [O agro ecological procedures ali overlhe world, a group of growers began to produce grape [uice, wine, and sparkling winefollowing these procedures. The partial change of consurner behavior is due to theperception of the benefirs that this kind of producr can bring to the human healthand to the environment. AlI products made from the sustainable viticulrure are certi-fied hy organizations registered in the Brazilian Ministry of Agriculrure, l.ivestockand Food Supply. However, so far data regarding heavy metal conrenrs is limited.Thus, 41 samples of agro ecological products derived from grapes were analyzed,i.e., 28 grape juices, 11 wines, and 2 sparkling wines. Samples were direct!y collecredin thc wineries and rhey represem products from the 2006 and 2007 vimages. Foreach product, rhe maxirnum, minimum, and mean concenrrations of the followingminerals and heavy metals were deterrnined: phosphorus, potassium, calcium, mag-nesium, sulfur, copper, zinc, iron, manganese, sodium, aluminium, cadmium, chro-mium, nickel, lead, molyhdenum, cobalt, arsenic, sclenium, and vanadium. Resultsshow that rhe concenrrations of the minerals of the agro ecological products were ac-cording to Brazilian legislation and those ofheavy merals presented very low values.
