dc.description.This study evaluated the influence of soil pH correction and potassium saturation on the quality of Brazilian tropical red wines 'Syrah' from São Francisco Valley. Soil pH correction and potassium saturation were established by applying elemental sulfur, calcium sulphate or potassium chloride to the soil. The experiment followed a 2x3 factorial with two levels of soil exchange complex saturation with base(V) and three percentage of exchangeable potassium in the soil(PKT). The treatments were T1= V 86% and PKT 2.5%; T2 = V 86% and PKT 4.6% (control); T3 = V 86% and PKT 10%; T4 = V 50% and PKT 2.5%; T5 = V 50% and PKT 4.6 %; T6 = V 50% and PKT 10%. The results show that high soil PKT value (10%) reduced must potassium content. Lower soil exchange complex saturation with base (V=50%) with median percentage of exchangeable potassium in the soil (PKT=4.6%) resulted in higher total polyphenols content and organic acid degradation in the berry. The V=86% plus PKT 4.6% and the V=50% plus PKT=4.6% resulted in wines with higher amount of precipitates and highest pH value. The results suggest that these soil management conditions will can promote a great effect on wine qualitypt_BR
