 ABSTRACT

       Wines produced in different geographical regions will each have their specific character dictated by the climate, latitude and altitude. In wine authentication a key issue is to find suitable markers such as oxygen, carbon and strontium stable isotopes which record the isotopic composition of the vine source of water and the climatic condition experienced by the grape vine. These stable isotopes have been explored extensively to detect wine adulteration or for proving the claimed origin. Also, wine aroma is a very important parameter in terms of rigorous quality requirements. This work gives an overview on the most sensitive techniques applied for wine fingerprinting, considering information about environmental and technological aspects of wine geographical authentication.

Keywords: wine, stable isotopes, fraud detection, ICP-MS, IRMS, GC-MS.
