Conteúdo: 	In Santa Catarina State, a new wine region is established in high altitudes areas, above 900 m, where, thanks to weather 
conditions it is possible to produce grapes with unique characteristics and high-quality wines. Temperature is the major 
climate element for grapevine development, controlling the rhythm at several phenological stages like bud break, flowering, 
veraison and maturity that occur during the biological cycle. In highlands of Southern Brazil, information about the thermal 
requirements of resistant varieties (PIWI) is lacking. The objective of this study was to determine the phenology and thermal
requirements of Felicia, Calardis Blanc, Bronner, Aromera and Helios. The experiment was conducted at Suzin Winery, located 
in the city of São Joaquim, Santa Catarina State (28°13'53,86" S, 50°4'14,75" W, altitude 1,100 m a.s.l.). The phenological 
stages evaluated were bud break, flowering, veraison and maturity, between the seasons of 2017/2018 and 2020/2021. 
Thermal requirements were calculated by growing degree-days, considering base temperature of 10°C. It was observed that 
the cycle of resistant varieties is shorter than the vinifera varieties cultivated in the region. The thermal durations are a good 
indicator of vine development phases. Among them, Aromera and Felicia presented the shortest cycle (155 days), Calardis 
Blanc and Helios had the longest cycle (166 days). The average heat summation for the evaluated resistant varieties was 1,470 
GDD. Varieties better adapted to areas of high altitude (1,100 m a.s.l.) should present budbreak in mid-September and harvest 
until the beginning of April. The resistant varieties Calardis Blanc, Bronner, Aromera and Helios are well adapted to high 
altitude conditions of Santa Catarina State. The variety Felicia may present adaptation problems, due to early bud break.
