Radiological and chemical fingerprinting can help to determine the year of production - vintage and the geographical provenance or designation of origin of high quality wines. Radiological and chemical investigations are performed on Bulgarian Melnik fine wine, as well as, on vineyard soil, grape stems and grape leaves. The gamma-ray activity of the radioisotope Caesium-137 has been measured in wines from different vintages using Low-Background High-Resolution Gamma-Spectrometry. The specific concentrations of 16 metals have been measured in samples from soil, grape stems, grape leaves and fine wine from Shiroka Melnishka ('Melnik') grown in typical Melnik vineyard by means of Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES). Radiological and chemical correlations obtained can be used as initial data base for determination of vintage back to 1986 and for eventual proof of designation of origin of Melnik fine wine.
