Word of advise especially when you have plenty of time on your hands. Make a yeast starter, this way you know the yeast is good. I dont do the rehydrate thing myself. I much prefer the starter or if not that just the sprinkle on top. So you let it sit 4 days after putting the stuff in before adding yeast. Id be careful waiting that long unless it was really cool although seeing that it was heavily sulfited you were safe in this instance.
