Italian immigrants introduced this thin-skinned red grape to California in the 19th century, though producers there still struggle to match Italian quality. In Italy's Veneto region, a small acreage is used to craft a rare recioto-style dessert wine from it. Which grape?

Question

Accepted Answer

Nebbiolo. Italian immigrants brought Nebbiolo grapes to California in the 19th century, but Nebbiolo has been hard to grow well there, lagging behind other Italian varieties like Sangiovese. In the Veneto, only a small amount of Nebbiolo is planted, and some producers use it to make a sweet Nebbiolo recioto wine.
