A bit confused about Star San

[Shooter]

Chemical burps sound phenolic, which could be either an infection, chloramines or underpitching your yeast. Not really something we see with starsan, since again, the starsan breaks down into some the same ingredients that exist in coca cola. Mostly phosphoric acid. I find it highly unlikely that starsan is the source of your burps. And frankly I think it's a step back to use one step, which isn't even recognized by the fda as a sanitizer.

Here's some info on phenols.

Thanks for the info Revvy, I will try changing up my water before I give one step a try. We will see.

I think this is a good plan. I once accidently racked a finished beer onto two cups of Star San sitting at the bottom of my keg. I somehow forgot to dump it out. The beer tasted just fine.
