Abstract
The fluorescence spectra of Bulgarian and French wines of the same price class were obtained at excitation wavelengths of 265 nm, 275 nm and 295 nm. The excitation-emission matrices are obtained and compared. A correlation between the emission maxima and the anthocyanins or the antioxidant activity expressed in Trollox units is obtained.
