The approval took place on October 16th, during the 24th General Assembly of the OIV, held in Yinchuan, China. The Portuguese proposal was coordinated by Professor Sofia Catarino (LEAF– Instituto Superior de Agronomia / University of Lisbon), coordinator of the National Experts Group on Analytical Methods of the OIV National Commission (CNOIV).
According to Professor Sofia Catarino, “the ⁸⁷Sr/⁸⁶Sr isotope ratio offers a valuable tool for geographical origin assessment, as it reflects the geological characteristics of the environment in which the vines grow. Wine authenticity and traceability are increasingly important in a globalized market, helping to protect consumers, safeguard wine quality, and support regulatory compliance.”
The OIV's adoption of this method recognises years of research, methodological development, and collaboration, highlighting the scientific contribution made by Portugal, the CNOIV, the Instituto Superior de Agronomia, and its Oenology group to the international harmonisation of analytical methodologies in the wine sector.
