Traditionally, in the viticultural regions of the Brazilian Southeast, grape harvesting occurs during summer, period of high rainfall, which predisposes the incidence of cluster rot and impairs the process of berry ripening. Wines made from those grapes, especially red wines, are thin, astringent, acid and without potential of aging. On the other hand, the recent increasing demand for fine wine consumption in Brazil led to a constant search for new viticultural areas with better conditions for grape ripening. In this context, the insertion of the Southeast region in the scenario of Brazilian fine wines is becoming possible due to double pruning management. This technique was tested by the Centro Tecnológico EPAMIG Uva e Vinho (CTEUV), at Três Corações, South of Minas Gerais State, aiming the improvement of grape quality through changing the period of harvest from summer to autumn – winter. Preliminary results of studies conducted by CTEUV showed that the climate conditions such as low rainfall, high insolation and high thermal amplitude, from May to August, were suitable to ripening and harvesting Syrah grapes. As a result, grapes presented an excellent maturation index, mainly the phenolic maturation. Studies carried out in the Northeast of Minas Gerais State, at Pirapora, also revealed a good enological aptitude. Syrah and Sauvignon Blanc are promising cultivars for the vineyards of Minas Gerais and São Paulo States. The inversion of grapevine cycle through double pruning management opens up a new possibility of viticultural activity in the Brazilian Southeast.
