I started using the stuff on my second brew, I'm brewing #11 tomorrow, and #12 will be all grain. I've never even come close to having a boil over since the first brew without the Fermcap.
Copied from another forum, and I don't think the author, Denny Conn, would mind me reposting it here.
I've been involved in discussions lately based on FDA warnings about using silicone based Fermcap S in unfiltered beers. While I haven't been able to find the FDA statement, I did fond this from Dana Johnson of Birko. They make a silicone based foam control product similar to Fermcap S. BTW, I've gone to using Fermcap AT, which has no silicone (AFAIK).
"Brewers should not use silicone-containing antifoam for unfiltered beers. The FDA allows active silicone to be used up to 10 parts-per-million (ppm) but stipulates that the silicone must be removed prior to packaging by either filtration or centrifugation. In the case of unfiltered beers, use a food grade, non-silicone antifoam. We sell a food grade, canola oil based antifoam that works well for this purpose and has an added benefit of being yeast-friendly at the same time. Look for my article on antifoams in the brewery in the July/August issue of The New Brewer. Please contact me directly if you would like to discuss this or any other matter further.
Cheers!
