Bottled by Delaage, Great Level The Beauregard estate as we see it today dates back to the late 18th century, the time of the construction of the current château and also when viticulture was established as the predominant activity on the property. The origins of the Beauregard estate perhaps lie with the Knights Hospitalliers of St John of Jerusalem, who owned and occupied a small house on the property during the 12th century.
