Book of abstracts... Petrolina: Embrapa Semiáridoc2016  ap. 46.  aThe predominant grapes in the São Francisco Valley (SFV) are from European origin (Vitis Vinífera L.). According to Pereira (2011) the tropical viticulture developed in this region differs from the traditional areas due to the capacity of a vine to produce more than one crop per year. Chenin Blanc is one of the main cultivar used to elaborate white wines, presenting a good adaptation to the soils and climatic conditions of the SFV area, and typical characteristics in the region. Climate changes according to the years and can influence wine characteristics (PEYNAUD, 1997). In this way, to evaluate effects of different vintages on physical-chemical characteristics of Chenin Blanc white tropical wines from SFV, this study was carried out. Wines used in this study were  laborated by traditional process to obtain dry white wines (PEYNAUD, 1997), at Embrapa Semi-arid, evaluating two seasons, the first one in July 2014 and the second one in September 2015. Vines were planted in a partner winery, cultivated in pergola, grafted onto IAC 572, and drip irrigated, in Santa Maria da Boa Vista, Pernambuco state, Brazil.  aGrapes  aUva  aVinho  aVale do São francisco  aVinho Chenin Blanck1 aSOUZA, J.
