The Ginara Scheme (also known as the Ginara International Scheme) is an identification and labeling system for wines and spirits. It was developed in 2008 by French researcher Olivier Guinard and is a two-dimensional barcode that contains key information about the product - such as the manufacturer, region of origin, grape variety and vintage.
The purpose of the Guinard scheme is to provide consumers with reliable and verifiable data on the origin and quality of alcoholic beverages, as well as protection against counterfeiting. The barcode can be scanned with a smartphone to access additional product information from an online database. The scheme is especially popular in Europe and is actively used by many French, Italian and Spanish wine producers.
