Penfolds wines enjoy great success in the secondary wine market in Australia and in many important wine markets across the world. They are amongst the most traded wines in Australia dominating the auction price charts.

Grange in particular has garnered a reputation that rivals the great classified growths of Bordeaux and Burgundy. The only Australian wine to be Heritage listed, it is a culturally significant wine that excites wine collectors and attracts strong demand on the secondary market. The 1955 Grange was listed by Wine Spectator Magazine as one of the greatest wines of the 20th century. Such international recognition is reflected in strong auction results around the world.

Joining Grange amongst the list of the most traded wines on the Australian secondary wine market are Bin 707 Cabernet Sauvignon, St Henri Shiraz, RWT Barossa Valley Shiraz, Bin 389 Cabernet Shiraz, Bin 407 Cabernet Sauvignon and Bin 28 Shiraz.
