Characterizing wine terroir using strontium isotope ratios: a review.

This paper presents a detailed review of the use of Sr/Sr isotope systematics for wine provenance studies. The method is based on the principle that the Sr isotope ratio in wine reflects that of the labile fraction of the vineyard soil from which the wine is produced. The review encompasses Sr/Sr data from wine samples published between 1993 and 2021 from terroirs in 22 different countries.
