You need to ask him.
Fart smell is hydrogen sulfide not SO2.
Sulfide is an indicator of yeast stress.
I have never before seen an association between Campden tablet use and hydrogen sulfide.
I’m asking you since you seemed to have an answer. Don’t sweat it…its Ok.
200+ brews using sulfites. Had sulfide once when using wlp380.
My fault most likely.
Thanks for the reply. Still doesn’t answer my question, but that’s fine.
I didn’t mean to imply that. I just wanted to point out that wort contains iron, copper, etc. regardless of what material one’s mash tun or chiller are made from. And that tannic acid is an effective chelator of iron (though apparently not of copper).
Yes, bravo Denny the best info/wisdom of this entire thread.
I’m not discounting lodo and if it makes those who employ it enjoy their brew day more brew on!
I’ll take the Denny approach everytime though.
