SO2 in Wine

[TonyR]

I understand that the free so2 will dissipate when wine is racked or during long term bulk aging. If wine is bottled and corked with high levels of so2 will the so2 dissipate with time as in over a year.

Yes. It will slowly dissipate. It could take a while, depending on how much you are talking.
