grape juice already treated w/ k-meta

[bcvwines]

For my next batch i purchased super maket brand grape juice. There is no sorbate but it says that it was treated with potassium metabusuflite. I called the supplier and they said it was treated with 60-100 ppm. Will this level still be present when I open the bottles. Should I just not treat it and let it air for 24 hours?

I would pour it all in a bucket and lay the lid on top for 24 hours. In the meantime make a starter. You should be ok then. It may take an extra day or so for fermentation to start.
