do I need to re-stabilise this before bottling?

[Mikeymu]

I have a gallon of elderberry wine that is two year's old. It was stabilised and back-sweetened to 0.999 about one year ago.

Is it a good idea to add anything to re-stabilise (or add another campden tablet for longevity) before I bottle it, given that I intend to leave it at least another five years before drinking - if I can be that strong-willed?

You definitely want to add another crushed and dissolved campden tablet, but you don't need to add any more sorbate.
