Effect of the vintage year on strontium isotopic ratio (⁸⁷Sr/⁸⁶Sr) of wines: a Portuguese case study.

ABSTRACT:

Background

Currently, there is a growing need for wine authenticity tools to face the global wine market and deal with adulteration cases. Stable isotope analyses, recognized by the Organization of Vine and Wine as a tool for detecting authenticity fraud, form the basis of the European Wine Databank, which faces limitations concerning the geographical origin of wines. Several studies were developed on applying the ⁸⁷Sr/⁸⁶Sr isotopic ratio to evaluate wine geographical origin, involving wine-producing regions worldwide. The most important feature of Sr, evidencing its reliability as a provenance tracer, is its assimilation by the vine plant roots in the same isotopic proportions in which they occur. Although important aspects such as ⁸⁷Sr/⁸⁶
