Some questions about Banyuls!

[quijote]

Wasn't sure if I should post this here or in the South France category, so please move this if necessary....

There are lots of posts in the archives in praise of Banyuls, but I have a few practical questions....

How long should a Banyuls age for? A store in Milwaukee has a couple of 1996 Chapoutier Banyuls at $18 per.... Since Banyuls is fortified and often likened to Port, I'm thinking the 1996 should be fine, but I'd like to hear what you all have to say about it.

Once I open a Banyuls, how long will it last? I've read that Ports, Tawnies, etc. that have been opened can last for at least a few weeks in the fridge. Is the same true of Banyuls? Or should it all be consumed upon opening?

Thanks for your help!

The '96 should be approachable. Treat it (stemware, fridge storage, et al) like a Port.

I have to admit that I never even thought of this question before, since most of the Banyuls I get comes in 375 or 500 ml bottles. But I think IK is correct.
