Viticulture in the Alto Adige has historic roots that preceded the Roman Empire. This region’s vineyards extend over the plains and hills surrounding the Isarco Valley and the Adige River whose valley is Italy’s corridor to Germany. Alto Adige is considered more Germanic than it is Italian and although the Trentino in the south tends to reflect Italian culture, it too remains more cosmopolitan, as exemplified in the international grape varietals so popular in this region. The most famous varietals are Gewürztraminer, Pinot Grigio, Pinot Bianco, Müller Thurgau, Riesling and Moscato. Trentino is also responsible for Italy’s largest production of Chardonnay and is a leader in sparkling wines.
