Because of that it should never be used instead of sulfite. The use
I've heard is adding some while bottling (and maybe racking) and
reducing the amount of sulfite used at the same time. It sounded like
too much hassle with doubtful gain, but it might make sense for people
who are sensitive to suliftes.
