Wine people are fascinated by the question of how wine ages at the bottom of the sea. A recent report on a barrel of 2009 Bordeaux red wine, aged in the oyster beds of the Bay of Arcachon for six months, has been doing the rounds. The wine was retrieved and compared with a barrel of the same wine aged in the winery’s cellar and found to be superior. It seems like drawing the longbow, but this experiment is being compared to the bottles of 200-year-old champagne found in a shipwreck at the bottom of the much deeper and colder Baltic Sea two years ago. The 11 bottles were sold at auction this month for £90,000 ($140,000). And in Greece, winemaker and a part-owner of Gaia Wines, Yiannis Paraskevopoulos, has placed a cage of bottles of his Gaia Santorini Assyrtiko white wine in the sea near his winery on the coast of Santorini.
