Until its integration into Europe in 1986, Portugal had a long tradition of exporting Porto and Madeira. Since then, there has been a revival of other Portuguese wines, rich in singularities, preserved by a traditionally traditional viticulture. The long isolation of Portugal has had the advantage of leaving intact the tremendous diversity of native grape varieties and maintaining unique know-how. Legislation modeled on the French model has made it possible to better frame this heritage. As a result, Portugal has been able to enhance its heritage while raising the level of its production to the current requirements. The most significant development was in Alentejo, where the extension of the vineyard did not take place at the expense of its identity.
