A collection of limited-release and rare Penfolds wines will be sold at the biennial Barossa Vintage Festival Rare Wine Auction in Australia.
The auction is being held at Penfolds Red Barrel Cellar in Nuriootpa on April 17, and will be seen as a barometer for the value of super-premium Australian Shiraz on world collector markets.
Penfolds chief winemaker Peter Gago said: "There are some very special wines on offer, in varying formats and across many decades, all with global reputations.
"The provenance of these wines is outstanding. Many have never left the cool dark confines of our wine library."
Lots include an imperial bottles of 2004 Penfolds Block 42 Kalimna Cabernet Sauvignon and a 1985 Penfolds Bin 95 Grange.
The auction relies on donations from the museum cellars of Barossa winemaker and raises funds for local marketing and wine education initiatives.
