Etna DOC affects the maturation of the grapes and therefore there is a significant difference between the harvest period of the Etna and the rest of the Sicily areas. The soil is volcanic and very rich in minerals. It is formed by the disintegration of one or several types of lava of different ages and eruptive materials such as lava, ash and sand. Containing all these particles, the crops cultivated on Etna soil benefit from nutrients like iron, copper, phosphorus, magnesium and others. Etna DOC Etna is a "Denominazione di origine controllata" (DOC) for wine from the Etna region in Italy. Etna
Mount Etna volcanic edifice, forming a stratovolcano in alternating explosive and effusive eruptions. The growth of the mountain was occasionally interrupted by major eruptions, leading to the collapse of the summit to form calderas. From about 35,000 to 15,000 years ago, Etna experienced some highly explosive eruptions, generating large pyroclastic flows, which left extensive ignimbrite deposits. Ash from these eruptions has been found as far away as south of Rome's border, to the north. Thousands of years ago, the eastern flank of the mountain experienced a catastrophic collapse, generating an enormous landslide in an event similar to that seen in the 1980
