Star san in beer

[danimal615]

I was battling boil overs like never before yesterday. I was spraying the foam with mist from my water bottle. Turns out that i grabbed my star san diluted bottle. I probably misted it with a good 5 oz of my mixture. What do you think this will do to the beer?

Absolutely nothing. StarSan is a contact sanitizer and the acids just become yeast food. You're fine.

It is dangerous! Send it to me for proper disposal.

Actually it will do nothing. My wife was always bothering me about the foam when racking into a carboy (she was sure it was soap and would be dangerous to drink) and one day I just grabbed my spray bottle and sprayed about three good squirts into my mouth and swallowed, followed by "It's not soap! It's not dangerous! It's fine!" On the plus side, I think my next dental appointment went better.

According to the Starsan MSDS, it has an evaporation rate of .9 (water = 1) and is completely soluble in water. My guess is that if you continued to boil after you applied it, it probably boiled off. I'm not a chemist or anything like that, so this is honestly just my best guess.

Sounds good! Thanks
