At the 2011 Nederburg Auction, a trio of 50-year-old bottles went for an impressive R20 000, the equivalent of R6 666 a 750ml bottle. The 1961 vintage wine was bought by a foreign company trading between Asia and Africa. There were two other lots of vintage Chateau Libertas that also fetched handsome prices. A six-bottle case of 1965 was sold to a local chain for R14 000 (or R2 333 a bottle), while a 1967 case of six bottles went under the hammer for R8 800 (R1 466 a bottle), sold to a Chinese buyer. Chateau Libertas was developed by Dr William Charles Winshaw in 1932 as an elegant Cabernet Sauvignon-based blend and has been made without interruption ever since.
