My first thought. Maybe I'm too cynical but I see this as a marketing ploy for the well-healed who will now say they simply must have the ocean-aged wine and turn up their noses at others who can't afford such a delicacy.
Yeah, okay.
I'm waiting for not only 'ocean aged', but specific places in the ocean. 'Mediterranean Sea aged', 'Indian Ocean aged', and rather than the far too common 'Atlantic Ocean', it'll be Bahama Ocean Aged, or Cape Cod Ocean Aged... ;)
