Os principais fatores que colaboram para esta vitivinicultura de baixas latitudes são: temperaturas elevadas ao longo do ano, precipitação pluviométrica moderada ou deficitária, radiação solar em abundância e água disponível para a irrigação. Podem ocorrer ciclos contínuos, onde quem decide quando podar e quando colher é o produtor, em função das estações chuvosas, das demandas do mercado, da estrutura física e dos tipos de vinhos elaborados. No Vale do São Francisco, Nordeste do Brasil, produz-se vinhos tropicais há mais de trinta anos. A vitivinicultura praticada na região é uma das mais tecnificadas do mundo, pois exige elevado grau de conhecimento dos viticultores e técnicos, em termos de manejo do campo, assim como diferentes conhecimentos dos enólogos durante as vinificações. São produzidos na região vinhos espumantes moscatéis, espumantes tradicionais secos e meio doces, vinhos tranquilos tintos jovens e de guarda e brancos jovens, além de vinhos comuns (de mesa), mais recentemente. Este artigo apresenta as características desta vitivinicultura jovem e diferenciada, quando comparada àquela praticada nos países produtores tradicionais, bem como resultados de pesquisas realizadas na região nos últimos quinze anos, em parceria com as vinícolas. Tropical wines are produced in winegrowing regions where vines can have more than one cycle per year and at least one harvest. The main factor contributing to this viticulture from low latitudes are: high temperatures throughout the year, rainfall level with moderate or deficient water supply, abundant solar radiation and water availability for irrigation. Continuous cycle happen and is the producer who decides when to prune and to harvest, according to rainfall season, market demands, physical structure and wine types elaborated. In the São Francisco Valley, Northeastern Brazil, tropical wines are being produced since the last thirty years. Viticulture practiced in the region is one of the most technified worldwide, because require high degree of knowledge of the viticulturists and technicians, for field management, as well as knowledges for enologists during winemaking. The region produce fine sparkling wines - dry or semi-dry, sweet muscat sparkling, young and aging still reds and young still whites, besides table wines, recently. In this article will be presented characteristics of this young and different vitiviniculture, as compared to that from traditional countries, as well as results of researches carried out in the region in the last fifteen years, in partnership with wineries. jeu., 13 sept. 2018 14:12:46 +0200 jeu., 19 déc. 2024 09:12:29 +0100 http://preo.ube.fr/territoiresduvin/index.php?id=1658 http://preo.ube.fr/territoiresduvin/index.php?id=1830 Les vins tropicaux sont ceux produits dans les régions vitivinicoles où plusieurs cycles végétatifs de la vigne peuvent se produire par an, avec au moins une récolte annuelle. Les principaux facteurs qui contribuent à cette vitiviniculture en basses latitudes sont : des températures élevées tout au long de l'année, des précipitations modérées ou insuffisantes, un rayonnement solaire abondant et de l'eau disponible pour l'irrigation. Des cycles continus peuvent se produire, et c'est alors le producteur qui décide quand tailler et quand récolter, selon les saisons des pluies, les demandes du marché, la structure physique et les types de vins produits. Les vins tropicaux sont produits dans le Vale do São Francisco, au nord-est du Brésil, depuis plus de trente ans. La vitiviniculture pratiquée dans la région est l'une des plus technicisées au monde, car elle exige un haut degré de connaissances de la part des viticulteurs et des techniciens, en termes de manipulation du terrain, ainsi que des connaissances différentes des œnologues lors de la vinification. La région produit des vins effervescents de muscat, des vins effervescents traditionnels secs et demi-sec, des vins rouges encore jeunes et de garde, et des vins blancs jeunes, en plus des vins communs (de table), plus récemment. Cet article présente les caractéristiques de cette vitiviniculture jeune et différenciée, par rapport à celle pratiquée dans les pays producteurs traditionnels, ainsi que les résultats des recherches menées dans la région au cours des quinze dernières années, en partenariat avec les domaines viticoles.
