Santa Ema was established by Pedro Pavone, the son of Italian winemakers from Piedmont in Italy. Having arrived in the Maipo valley of Chile in 1917, Pedro was an engineer by trade and spent his early years grape growing for other wineries, having planted his first vineyards in 1931 and harvesting his first cabernet, Merlot and sauvignon Blanc grapes four years later. He then established the winery with his son Felix in 1955. Santa Ema produces Chardonnay, cabernet sauvignon, Merlot and Sauvignon Blanc in addition to a reserve range, Barrel Select line, and a Bordeaux-style red blend called "Catalina" which consistently earns praise for each vintage. Santa Ema was named one of the 20 "World's Finest value Brands" by Wine Spectator in 2005.
