Brazil. The wines were originated from Campo Belo do Sul (27??40'4" S, 50??44'48" W, altitude 950m asl) and S??o Joaquim (28??16'31? S, 49??56'09" W, altitude 1,400m asl), Brazil, in the 2013 season. In vitro antioxidant activity was analyzed by DPPH and ABTS methods. The phenolic content was determined by high-performance liquid chromatography, and were quantified the main flavonoids compounds and non-flavonoids compounds. Wines produced in Campo Belo do Sul (950m asl) had markedly elevated concentration of total monomeric anthocyanins, with 295.9 e 588.5 mg L-1 for Merlot and Cabernet Sauvignon, respectively. While the wines produced in S??o Joaquim (1,400m asl) stood out due to high anti-oxidant activity, with 5268.3 e 5243.1 μmol for Merlot and Cabernet Sauvignon, respectively. Also the wines of S??o Joaquim showed higher levels of flavonols and trans-resveratrol. Based on the wines phenolic profile it is possible to affirm that Campo Belo do Sul (950 m) has a higher suitability for produce Merlot wines, while S??o Joaquim has a greater aptitude for produce Cabernet Sauvignon wines.  aanthocyanins  aflavonoids compounds  anon-flavonoids compounds1 aBRIGHENTI, A.
