Hey guys and gals,
If I crushed up and added three campden tablets, added it to six
gallons of apple juice from a local orchard, and pitched WL cider
yeast 7 hours later will it be fine? Or would I have poisoned yeast?
The cider yeast had a 6 hour head start in a pint of unsuplhited apple
juice.

(I understand that cider seems to be a .brewing topic generally, but
sulphite expertise isn't there like it is here.)
