In the mid-nineteenth century, two of the leading Chilean wine producers brought vines from Bordeaux to improve the quality of the original vineyard of Viña Los Vascos. Chile's natural geographic frontiers protected it from the Phyloxera epidemic of the late nineteenth century and resulted in an unbroken line of wine stock that now produces some of the finest wines in all of Chile. The acquisition of 50% of Los Vascos by Rothschild (Lafite) in 1988 was the result of an exhaustive search of more than one hundred Chilean wines for one that could meet their criteria for excellence. The vineyard's own Chardonnay grapes are complemented by a selection of grapes from the Casablanca valley located further north between Santiago and Valparaíso, which is renowned for its great Chardonnay production.
