In answer to how long can you keep red wine. Me personally no time at all! Realistically some wines are good for many years and others made to be drunk quickly like Beaujolais Nouveau. You will have to open it and taste it. I will be available any time later to help!
In a sealed bottle I'm unsure there is a limit. They are removing bottles from long sunk ships and trying them aren't they ? That said I'm unsure the taste would be up to much, but must be worth a try.
There is no problems with red wine,most white wine should be drunk within 10 years normally.
I'm sorry I have not got a clue about Red Wind Bottles though.Best advice I can give is smell them first
It won't kill you, but it might not be very nice by now. It will depend on the quality of the wine (the great wines can take 20+ years before they should be drunk, and can still be excellent after 50+ years) and how it was stored (standing up in a room with temperature changes is not ideal).
Open it, test a little, and then be prepared to let it breath for 2-3 hours after decanting
