Lagarino bianco is a white Italian wine grape variety that is grown in the Trentino-Alto Adige/Südtirol wine region of northeast Italy. It was once thought that the grape was a white berry color mutation or offspring of South Tyrolean grape Lagrein with a weiss Lagrien grape variety reportedly growing near the commune of Bolzano in 1318 but DNA profiling conducted in the early 21st century has shown that the two grape varieties are distinct with no direct relationship to each other.[1]
Lagarino bianco was nearly extinct until viticulturists at the Istituto Agrario di San Michele all’Adige (IASMA) in San Michele all'Adige worked to revive the variety and since 2007 the grape has been listed in the official Italian registry of grape variety. While the grape is not widely cultivated, some producers in the Trentino-Alto Adige/Südtirol region are producing varietal examples of Lagarino bianco.[1]
