I've had a good scout around here, but I can't seem to get a definative answer.
Would Metabisulfite (sodium or potassium) be usable as a no rinse sanitiser? It seems okay for wine, so I'd assume it would be okay for beer, but I was planning using this for everything but I'd be a little bit scared of killing of any yeast when I bottle.
I would have thought though that the yeast would be well snough established that it wouldn't matter, along with the meta being so dilute. Any advice apperciated!
