Conteúdo: 	The use of non-traditional grape varieties for elaboration of sparkling wines is a challenge for the
winemaking industry. The Goethe variety stands out as being a typical cultivar of the Urussanga
Region in the south of Santa Catarina State, Brazil, where most of its production is directed to the
elaboration of still wines. The objective of this work was to characterize the base wine and sparkling
wines (cv. Goethe) regarding classical oenological parameters and evaluate the influence of aging on
lees of sparkling wines in the evolution of phenolic compounds, antioxidant activity in vitro and
browning index. The samples were analyzed relating the oenological parameters and monitored for 15
months of aging on lees to verify the evolution of total and individual phenolic compounds
(hydroxycinnamic acids). The results showed that during aging on lees, the sparkling wines had an
increase in antioxidant activity in vitro. As for total phenolics, there was a decrease in concentrations
after 15 months of aging. Among the hydroxycinnamic acids, trans-caftaric acid was the most
abundant. During the aging the concentration of caffeic acid increased in the sparkling wines (0.91 mg
L-1) in relation to the base wine (0.41 mg L-1), and by correlation analysis it was possible to observe a
strong correlation (r=0.90) between this compound and the antioxidant activity. These results
demonstrated the great potential of using the Goethe variety for the elaboration of sparkling wines.
