 Very vigorous vines, these varieties are able to produce many clusters weighing as much as 9 pounds (4 kg) and tend to produce pink or deeply colored white wines that oxidize easily and often have noticeable sweetness.These varieties are often used today for bulk jug wine sold in 1 liter cardboard cartons or as grape concentrate which is exported worldwide with Japan being a considerably large market.In the late 20th century, as the Argentine wine industry shifted it focus on premium wine production capable for export, Malbec arose to greater prominence and is today the most widely planted red grape variety followed by Bonarda, Cabernet Sauvignon, Syrah and Tempranillo.
