 Most of the wine production in the Americas is based on Old World grape varieties, and wine-growing regions there have often "adopted" grapes that have become particularly closely identified with them.California's Zinfandel (from Croatia and Southern Italy), Argentina's Malbec, and Chile's Carmenère (both from France) are well-known examples.Until the latter half of the 20th century, American wine was generally viewed as inferior to that of Europe.
