A new laboratory technique could make it quicker and more accurate to confirm where a wine was produced. By analysing the wine’s unique inorganic ‘fingerprint’, researchers say the method could strengthen anti-fraud checks and improve confidence in origin claims.
Scientists have developed a faster way to verify a wine’s geographic origin by measuring 23 inorganic elements with exceptional precision. Published in Food Chemistry, the technique uses advanced mass spectrometry to create a detailed elemental profile that reflects the soil, water and growing conditions where the grapes were cultivated.
The researchers found the method can reliably distinguish wines from different regions, offering laboratories a powerful new tool for authenticity testing. Compared with existing approaches, it delivers improved speed and analytical accuracy, making it more practical for routine checks.
If adopted more widely, the technique could help wineries, importers and regulators confirm provenance, protect appellations and reduce wine fraud. As demand for trusted origin claims grows, this chemical fingerprinting method could become an important safeguard for both producers and collectors.
