This was oxidized.  It's hard to say Pre-Mox since it is 17 years old, but this should not have been in this shape.  It had been purchased a decade or so ago and well stored since then.  Deep gold in color.  The nose is slightly oxidized, but not quite to a "sherry" level.  On the palate, there is some lime fruit and a bit of butterscotch.  But it is oxidized more than the nose.  Perhaps still a bit drinkable but why?  White Burgundy issues have extended into some Chablis wines, but it's hard to say that is what happened here.  This seems more of a less than great cork and a 17 year old Chardonnay.
