The "Marque Nationale des Vins luxembourgois" was introduced on 12 th March 1935. The distinction "Marque Nationale - Appellation contrôlée" on the rectangular label affixed to the rear of the bottle certifies the state-controlled production and quality of the wine.
Wine with this quality label must undergo a comprehensive chemical analysis in the laboratory of the State-run Institut Viti-Vinicole (IVV). It must achieve a score of 12 out of 20 points in an organoleptic examination of its colour, clarity, bouquet and taste. This examination is carried out predominantly by members of the tasting committee of the Marque Nationale for Luxembourg Wines ("Commission de la Marque Nationale des Vins Luxembourgeois"). If it scores 14 points it can be called a "Vin classé", 16 points makes it a "Premier Cru", and 18 points gives it the title "Grand Premier Cru". For descriptions such as "Vendanges Tardives" (late harvest), "Vin de Glace" (ice wine) and "Vin de Paille" (straw wine) there are additional criteria to be observed, which have been regulated since 8 th January 2001.
In earlier times Luxembourg produced predominantly Elbling wines, exported to Germany and blended with other varieties in the production of that country's sparkling wine. Since the beginning of the 20 th century, there have been great changes in the winegrowing region: various varieties have been introduced and their yield strictly governed over the last twenty years.
A generation of young and innovative winegrowers has arrived, combining considerable specialist expertise with the most modern winemaking techniques. With advice from foreign oenologists, they have paved ever new paths, achieving a spectacular improvement in quality which has gained them well-deserved recognition in international competitions.
