Interesting, although I'm not sure the CEO of the company selling the wine is going to be especially objective.

It does raise a question - for wines that a vintner wants to age for a really long time, why would they use UV-transparent glass bottles and cork stoppers? Surely a glass bottle that's opaque to UV light would be better, as would a non-porous stopper. Even in the mid-19th century they had access to those things. Dipping the entire bottle in wax would do the job. I've never seen it done though (not that I'm any sort of wine expert).

Yes folks, these wines will still be drinkable. I've had 1929 red Burgundies on more than one occasion and can confirm that aged wine is not only drinkable but enjoyable. I was in Bouchard's cellars last November and can tell you that their storage facilities are top notch.

Salient point (TIL)...

We also check our bottles regularly and replace the corks every 25-30 years, which gives us an opportunity to monitor the quality of the wine.

---- Presumably they are checking its 'drinkability' among its other qualities!

So is it drinkable or not?

Did I miss the part where they answer the question?
