Sir Bobby Charlton, Gary Neville, Bryan Robson and Nicky Butt enjoyed a tour of Pirque Casona, near the Chilean capital of Santiago, and took part in a meet and greet session with staff of the world-renowned winery.
A highlight of Pirque- one of Latin America's biggest tourist attractions - is the famous Casillero del Diablo (The Devil's Cellar). This was the original cellar built by the founder of Concha y Toro to house his wines. After some of his wine was stolen, the founder - knowing how superstitious the local people were - started a rumour that the devil lived in the cellar. No wine was ever stolen again.
Before descending the steps into the cellar, the four Manchester United legends were officially welcomed into the exclusive Concha y Toro Brotherhood in a traditional ceremony in which members are presented with traditional Chilean ponchos.
The United legends were also joined by Raúl Bustos, Samuel Avalos and Juan Illanes - three of the famous miners who were dramatically rescued last year after a terrible month-long ordeal of being trapped in the mine where they worked in the Atacama desert, north Chile.
Also while in Chile, the quartet launched the Latin American leg of the Champions Trophy Tour. The Premier League trophy is being taken to Mexico, Ecuador, Brazil and Argentina to enable fans in those countries to share in United's record 19th league title success.
