Beginning shortly after the unification of their country in 1861, millions of Italians emigrated to the United States and to Canada and countries in South America. Many brought grapevine cuttings with them.
Never be surprised to see an Italian surname among the descendants of those immigrants making wine in the Americas today (for just two examples, Zuccardi in Argentina or Pisano of Uruguay). In the United States, Italian-born winery and winemaker names are nearly as ubiquitous as vines.
