The northern area of the Italian double region Trentino-South Tyrol; the southern area is Trentino. The Italian name is Alto Adige. It corresponds geographically to the Autonomous Province of Bolzano (Italian: Bolzano). The Rhaeto-Romans planted the first vineyards here as early as 1,000 BC, making South Tyrol one of the oldest German-speaking wine-growing regions. Here the Romans learned from the Celts how to use wooden wine barrels for storage and transport. In the Middle Ages, viticulture reached its peak. The German emperors who went to Rome for their coronation got to know and appreciate South Tyrolean wine on their travels. A decline occurred from the end of the 19th century, as in many other wine-growing regions, due to phylloxera and mildew. After the First World War, when South Tyrol was annexed to Italy in 1919, the northern sales markets were lost. After the loss of quality in the 1980s due to the marketing of mass-produced wines, there was now a return to top quality.
