Summary:
The origin and the variety of a wine can determine its quality and the price
the consumer will be willing to pay. Many factors can be studied in order to be
able to discriminate wines by their destination of origin or by variety, using
lots of analytical methods. Multielement analysis of wines has been applied,
the latest years, in order to classificate wines by their variety or their
origin.
A method of determination of the elemental content of wines after microwave
assisted digestion with nitric acid using Inductively Coupled Plasma Mass
Spectrometer (ICP-MS), has been developed. The data received have been used in
order to create an elemental fingerprint of “xinomavro” wines produced in
Greece. Xinomavro is a PDO wine and its elemental content has been compared to
this of other wine samples produced in Greece in order to achieve wine
classification, whilst investigating wine authenticity. Calculations included
the following elements: Li, B, Ti, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ge, As, Se, Rb,
Sr, Mo, Rh, Pd, Ag, Cd, In, Sn, Sb, Re, Os, Ir, Pt, Au, Tl, Pb, Eu, Gd, Th
determined by High Resolution ICP-MS.
