Number of investigations shows that consumation of foods and drinks with high content of antioxidants have preventive or therapeutic effect towards many illnesses. Grape, as well as wine /especially red wine/ and juices prepared from grape are among the foods that have high concentration of natural antioxidants. In the present work total antioxidant capacity -TAC of 7 different grape varieties was investigated. Three of the grape varieties are typical wine cultivars: Cabernet sauvignon, Strogosia and Gamza. The other 4 varieties Bolgar, Brestovitsa, Palieri and Hamburg misket are mainly desert varieties although they can be used for wine production as well. For TAC analysis two standard analytical tests were used: FRAP and TEAC. The highest TAC was detected in Palieri /4.4 µmol Fe2+/g FW for FRAP, 2.8 µmol Trolox/g FW for ТЕАС/ and Cabernet sauvignon. With lowest TAC was Gamza variety /2.6FRAP, 1.4ТЕАС/.
