Hi Greg,
High humidity and mold only look bad, the wine is still ok with a
quality cork. Wine has been stored in damp caves for 100's of years;
I'm pretty sure that is why capsules started being used. (I'm not
saying you should just let it grow like crazy in a house, there are
other reasons why that may be unwise.)

It depends on the quality of the cork and its length as to how long
before replacement. Expensive wines are usually recorked every 20
years and topped up at that time, there is a small industry that does
that for the incredibly rich. That topping wine is always an
interesting situation if you don't have a bottle of the exact same
thing, and you need less than an ounce typically.

I have one bottle of 96 left we should be drinking soon; it's a white
with high acid, that's one of the reasons I quit bottling dry white
over 6.5 g/l TA.

Mine will never 20 years, I'm not sure anything we make here improves
beyond 3 years. I have a few Chancellors that were way too tannic
that are over 6 years old, those are staying put for a few more years.
I try a bottle every year or so to see if it's getting any better,
it's been 'stuck' at the same 'still too tannic' level for 4 years
now. It's not getting worse, just not ready to drink.
Regards,
Joe
