Hi,
The location of the shipwreck? the mean temprature that the bottle sat at.
I'm afraid that unless it was very very cold were it was. I don't belive there
is much chance that its any good.
I belive there was recently a bunch of champange found in a shipwreck in very
cold water and they seemed to have survived anyone still have the URL for that?
Cheers,
Dave
PS doesn't mean it isn't a neat find!
