The GPE Association contains various requisites in its statutes which include that the wine must come from an exceptional single vineyard, that its winery should have attained a demonstrable fame with at least five years of recognised prestige in the marketplace and high marks in national and international competitions. The winery must pass a meticulous inspection by a technical auditing committee, and its wines must surpass the quality requirements set at a vertical tasting to be conducted by the general assembly of our Association.
