 In addition to producing premium red varietals made from Syrah and Douce noir (known locally as Bonarda), the San Juan region has a long history of producing sherry-style wines, brandies and vermouth.The high yielding Cereza vine is also prominent here where it is used for blending and grape concentrate as well as for raisin and table grape consumption.Recently, the higher-altitude vines planted in the Pedernal valley in Western San Juan, one of the most isolated regions in Argentina, have received significant acclaim for their potential to bring fame to the province's wine industry.
