The 87Sr/86Sr isotopic ratio is a well used marker for geographical origin reflecting the geology on which the crop or animal is raised. It has already been used as a provenance marker for evaluating of wine geographical origin from wine producing regions worldwide. This paper discusses the challenges on using strontium isotope signatures for wine authenticity and provenance. It recomends having a robust database of strontium isotopic values, as well as combining it with other discriminating parameters, namely trace elements for the identification of wine provenance.
