A TRAILBLAZING wine maker is undertaking a crackpot plan to mature his wine underwater.
Ronda vineyard owner Federico Schatz has placed a series of cases of his award-winning wine under the sea, near Marbella, to see how it evolves.
The German winemaker, who first planted his vineyard in 1982, was inspired by wines discovered on shipwrecks from the Roman era that were still drinkable.
The wines have been placed in a cage and submerged at a depth of 20 metres.
He wants to discover if there is any difference in taste between wine matured on land or under water.
Beware scuba diving theives.
