A capillary electrophoresis (CE) method has been developed and validated for determination of organic acids (oxalate, tartrate, malate, malonate, pyruvate, succinate, acetate, citrate, and lactate) and inorganic anions (sulfate and phosphate) in red wines. The separations were carried out in an automated separation system equipped with wide-bore (300 μm i.d.) fluoroplastic capillary and contact conductivity detector used for monitoring the separation and quantification of the analytes. The fast method (analysis time less than 5 min.) provided a good linearity of calibration curves (R 2 > 0.9920) for the studied acids, as well as a good reproducibility of migration times (RSD
