Hi,
Star San needs to be under a 3.5 PH to be effective although it will still kill up to 4 from what I here. Just not as effective. What makes Star San 'no rinse' is that you are going to dilute it with a HIGHER ph wort. This will 'de-activate' the Star San. I think a lot of people do not understand what makes star san 'no rinse'. If the concentration is too strong, it is no longer 'no rinse' and it will kill your yeast. A brew lore myth got created that Star San will kill everything but your yeast. Like somehow it's magic and will kill the foreign yeast and not your WP001. Have a bunch of star san foam sit in your little 1L starter and add your 5.2ph wort to it and see what it does to your yeast if you get it down to 3.5ph. Am I off base here?
I'm trying to figure out Iodophor, but there's just sooo much food industry info on that it's too much to sift through so I'm hoping someone here knows the answer.
Does Iodophor act like Star San in it's PH? What makes it no-rinse or 'de-activates' the killing action of Iodophor?
Also, my 'Homebrewing for Dummies' book calls sodium metabisulphite 'no rinse'. I was told that for beer you can't use it.. Any info on that would be great appreciated.
Thanks!
