According to an unlikely hypothesis, the distillate obtained from marc was allegedly produced in Italy as early as the 5th century. There is documentary evidence, however, that production and export to many countries took place in the 15th century. This makes Grappa one of the oldest distillates, along with Armagnac and Cognac. During the First World War (1914-1918), Grappa In Italy was distributed to soldiers to strengthen their morale and, after the Isonzo battles with their heavy losses, became an almost heroically transfigured national drink. At the instigation of the Italian state, an EU regulation was passed in 1989 stipulating that the name "Grappa" may only be used for marc spirits produced in Italy. Finally, in 2002 this was also permitted to the Italian-speaking areas of Switzerland. Various producers circumvent this by using fantasy names such as Grapillon Grapin, Grappina, Grappinot, Grappo and Grappolo.
