And what is the right way? the way you say to do it? you just dont get it. This thread is so far off topic its sickning. If you all have such a problem with star san and its so unsafe and poisonous, lets just outlaw it and stop using it. My god.
First, it's not off topic. We're discussing using starsan as an acid source to modify pH, aren't we? The OP asked for comments. You seem to think that anything aside from praise is out of line.
You're also creating a strawman argument saying people are objecting because they think starsan is "poisonous and unsafe." If others are saying this at all (I never did) they are probably referring to that concept that when you use starsan NOT as directed, it certainly does have deleterious and unwanted effects.
My point, demonstrated by the example of the Austrian wines is simple: just because an innovative and alternate solution to a problem has a similar result, it doesn't mean it is equally as good. Will starsan lower pH? Sure. Will one tiny drop in a gallon of water have any bad side effects? Most likely not. In an emergency, that's a pretty good stop gap measure and a clever one, I can see that. But to make it your go-to process is just laziness. And that's just an opinion. To me, it's like someone who can't be bothered to go get a hammer so they try to pound a nail in with a rock. In a pinch, it gets the job done. But I'd never rely on the rock as an everyday tool when hammers are easy to come by.
