[et al.] - Defining the uniqueness of monovarietal wines from native portuguese varieties of Vitis vinifera. In Congresso Mundial da Vinha e do vinho, XIII, Lisboa, Portugal, 22-27, June, 1998 - Novos mundos para a viticultura mundial: proceedings. Lisboa. p. 83-88http://hdl.handle.net/10400.14/6248Studies have been carried out on red and white monovarietal wines vinified during the 1995, 1996 and 1997 harvests. The essential aim being to evaluate sensory quality, correlate it with chemical analytical data and relate these to the various winemaking options available. Hence selective native varieties from the Douro, Dao, Bairrada and Vinhos Verdes regions have been studied and the analytical / sensorial data correlated to such factors as grape maturation and maceration regime. Results are presented illustrating the quality effects of variety / winemaking practice combinations, both in terms of analytical data (sensory and chemical) and taster preferences.engPortuguese varietiesWinemakinAromajournal article
