Geographical Indications (GIs) — in the EU - Protected Designation of Origin (PDO) and Protected Geographical Indication (PGI) — legally link a product’s name to a defined place, production methods, and quality criteria. For wine, GIs codify terroir, grape varieties and traditional practices into a product specification and a control system. That formal link protects reputation, reduces information asymmetry for buyers, and creates a credible, collective brand that individual producers can leverage.

Tradition and regional authenticity are powerful market signals. Consumers often use origin and stories of place as cues for quality, leading to higher trust, purchase intent, and willingness to pay. Beyond direct price effects, well-managed GIs support collective marketing efficiencies, easier export access, wine tourism, and rural development by keeping value in the producing territory and preserving local varieties and know how.

The latest study on geographical indications showed that the value of sales of a product with a protected name is on average twice as high as that of comparable products without certification. Geographical indications highlight the EU's culinary expertise but also bring clear benefits to the rural economy.
As of 1 October 2023, the European Commission had registered a total of 3,552 names, including 1,656 wines, 1,634 foods and agricultural foodstuffs, and 262 spirits.

EU funds can accelerate promotion of wines produced under Gis in European market and third countries market and capacity-building, but only when producers present a coordinated, credible plan linking authenticity to measurable market outcomes.
