Winemaker Penfolds has released 330 bottles of a 50-year-old port at £1,900 each through its cellar door as well as travel retail outlets across the world.

Penfolds 50 Year Old Rare Tawny is said to boast a "silky and luscious" palate with "concentrated flavours of mocha, chocolate, fruit cake, salted plum and savoury spice." It is suggested that the drink is consumed immediately, rather than cellaring it.

"This is an extraordinarily expressive and evocative wine. This is our history in a bottle" Penfolds chief winemaker, Peter Gago, said.

"Our hopes and aspirations across a hundred years are somehow distilled through this wine" he added.
