Consumers are increasingly requesting food and beverages to be authentic, especially when it comes to wine and its concept of terroir. Lambrusco wine has a Protected Denomination of Origin (PDO) status—only wine that is grown in these specific regions in Italy can be labeled Lambrusco. In this study, chemical and isotopic compositions were used to determine geographic origin. Specific boron, strontium and lead isotopes can be used to determine climate conditions and plant localities, translating into geographic locations of origins of food and beverages.
