Trentino-Alto Adige Trentino–Alto Adige is the northernmost Italian region, comprising two areas with very different personalities: the Germanic Alto Adige or Südtirol, which borders and once belonged to Austria, and right below it the more Italian but still very Alpine Trentino. The region’s capital and largest city is Trento, followed closely by the Südtirol provincial capital, Bozen (Bolzano). The breathtaking valley of the Adige River is renowned in the wine world for varietally labeled cool-climate wines, mainly white. It has no DOCGs, eight DOCs (see map), and four IGPs. In 2015, Trentino–Alto Adige produced 1.2 million hectoliters (13.7 million cases) of wine, almost three quarters of it white and 89% at the DOP level, the highest percentage of any region. The region’s primary grape varieties are Chardonnay (22%), Pinot Grigio (19%), and Schiava (9%).
