Don't Fear The Foam!!!
Starsan, at proper dillution breaks down and is eaten by the yeast, it shouldn't and doesn't affect the taste of our beer.....
Hence all these pictures by us in this thread,
"Stupid Starsan Tricks" or why you shouldn't fear the foam...
Most of the sanitzers we use, especially Starsan and iodophor are
No rinse/wet contact sanitizers. They are literally double edged swords. They kill two ways. They kill everything on the object prior to sanitizing, and then as long as they are still wet they form a sanitizer barrier that kills everything that comes into contact with object.
If you let the sanitizer dry any micro organism that comes in contact with the sanitized object, rather than being killed by it, makes the object no longer sanitzed.
If you let it dry you are reducing it's efficacy by 50%
You really want to sanitize right at the time you are using the thing you are sanitizing. And let the wort/beer flow on top of it.
I put a lot of good info and tips of effectively using sanitizers in here.
