Organic Wines

We have been given a bottle of Chardonnay Vin de Pays des Coteaux des Baronnies. It seems rather sedimenty and we wondered if this is how it should be. Or is it off?

It is showing a 1996 label and is a reddish color but on the back it says it has a buttery nose and perfectly balanced by citrus flavors.

Can you advise please?

This wine was meant to be drank within a couple of years of its creation, certainly not later than 2000. By now it is very oxidized, having turned from clear yellow to dark to orange or reddish which means an advanced state of evolution. While some rare people enjoy the "maderization" effect of oxidation it is not what this wine was supposed to become. It has simply been forgotten and will now end up in the sink unless you can find a use for it in cooking!
