supports: Denominazione di origine controllata (DOC) (English: controlled designation of origin) is a quality assurance label for Italian wines. The system is modeled on the French "Appellation d'origine contrôlée" (AOC) designations. The Italian government introduced the system in 1963 and overhauled in 1992 to comply with European Union law on protected geographical designations of origin, which came into effect that year. Verdeca is a white Italian wine grape variety that is primarily grown in the Colli Piacentini region of Emilia-Romagna in central Italy and Apulia in southern Italy where ampelographers believe that the grape may have originated. In Apulia, it is one of the main grapes in the "Denominazione di origine controllata" wines of Locorotondo DOC and Martina Franca DOC along with Bianco d'Alessano. In Campania, it is grown on the slopes of Mount Vesuvius where it used as a blending variety with Falanghina, Coda di volpe and Greco in both the white wines and the sweet dessert wine of the region, Lacryma Christi. It is also a minor component used in the some vermouth production. The Colli Piacentini ("Hills of Piacenza") is an Italian wine region located at the western end of Emilia-Romagna. In 1967, it was given the "Denominazione di origine controllata" (DOC) quality designation. Within its boundaries are several smaller DOCs including Colli Piacentini Gutturnio, Monterosso Val D'Arda DOC, Trebbianino Val Trebbia DOC and Val Nur del Colli Piacentini DOC. The region has a long history of winemaking with fossilized vine roots and grape seeds excavated from the region showing viticulture taking place as early as 2000 BC. In Roman times, Julius Caesar's father-in-law Lucius Calpurnius Piso Caesoninus, grew grapes in the Piacenza hills. Lacryma Christi , ( also Lachryma Christi of Vesuvius , literally `` tears of Christ '' ) , is the name of a celebrated Neapolitan type of wine produced on the slopes of Mount Vesuvius in Campania , Italy . White Lacryma Christi is made mainly from Verdeca and Coda di Volpe grapes , with smaller proportions of Falanghina , Caprettone and Greco di Tufo included . Red Lacryma Christi is made from Piedirosso and Sciascinoso grapes . It is also , as archaeologists have discovered , the nearest equivalent to wine drunk by the Ancient Romans , having analysed microscopic residue left on the taps of the casks . An appellation is a legally defined and protected geographical indication used to identify where the grapes for a wine were grown; other types of food often have appellations as well. Restrictions other than geographical boundaries, such as what grapes may be grown, maximum grape yields, alcohol level, and other quality factors, may also apply before an appellation name may legally appear on a wine bottle label. The rules that govern appellations are dependent on the country in which the wine was produced. Wine (from Latin "vinum") is an alcoholic beverage made from fermented grapes. These grapes are generally "Vitis vinifera," or a hybrid with "Vitis labrusca" or "Vitis rupestris". Grapes are fermented without the addition of sugars, acids, enzymes, water, or other nutrients. Yeast consumes the sugar in the grapes and converts it to ethanol and carbon dioxide. Different varieties of grapes and strains of yeasts produce different styles of wine. These variations result from the complex interactions between the biochemical development of the grape, the reactions involved in fermentation, the terroir, and the production process. Many countries enact legal appellations intended to define styles and qualities of wine. These typically restrict the geographical origin and permitted varieties of grapes, as well as other aspects of wine production.
