The aim of this study was to monitor the phenological
parameters of grapevine (Vitis vinifera) of Syrah
variety recently introduced in the region of Marari, A ¿ gua
Doce, Campos Novos and Sa?o Joaquim, Santa Catarina
State (SC), Brazil, and to characterize the phenolic composition
and antioxidant activity of wines produced from
this variety of the vintages 2010 and 2011. The adaptation
of the grapevine to climate conditions of these grape
growing regions of Southern Brazil for this variety has also
been assessed. The climate variations occurring between
the phenological cycles of grapevine of Syrah for each
growing region influenced the phenological extension and
heat accumulation of the grapevine. The wines showed
significant levels of phenolic compounds and high antioxidant
activity, while catechin, a potent antioxidant, was the
main phenolic compound quantified in wines. Positive
correlations between the phenolic compounds and antioxidant
activity were observed. The principal component
analysis confirmed the influence of the growing region and
vintages on the phenolic composition of wines, indicating
the importance of climate conditions. This study identified
possible phenolic markers indicative of climatic influence.
