Symington FamilyEstates owned Cockburn's Port has been re-launched with a bottle design based on the original 1970s model and an enhanced flavour.
In 2010, Cockburn's celebrated its 195th anniversary by returning to family ownership and is now benefiting from major quality improvements as well as an investment programme.
The re-launch also includes the introduction of a new bottle design - which was created by London based agency Bloom and based on the Cockburn's classic original design of the '70s.
Paul Symington, joint managing director, said: "We are committed to reviving the fortunes of this iconic port brand by restoring the quality that was the hallmark of its heyday.
"Cockburn's has gone back to its roots in the Douro vineyards."
The range includes Cockburn's Special Reserve, Late Bottled Vintage, 10 and 20 Year Old Tawny, Quinta dos Canais, Vintage Port and Ruby, Tawny and White.
