Where did you hear that?

Answer my own questions with Google.

"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!

Since I found out that Fermcap is supposed to be filtered out, I've cut way back on my use of it.  For instance, I've gone back to using a spray bottle of water to control the boil.  I"ll still use it when I have to, but I use as little as possible and avoid it if I can.

Where did you hear that?

Probrewer forum and data from one of the wholesalers who sells Fermcap.

" It is adsorbed onto the surface of the yeast, vessel walls and filter media. "

I thought the site I found said that only Fermcap S must be filtered, Fermcap AT does not. No real distinction on your link.
 
I only use it in starters, but that makes me wonder. Good old paying attention works for the kettle.

I had heard that also, so I bought some AT.  But I've come around to your way of thinking...I use a little for starters, but I'm back to using a spray bottle for the kettle.

Fermcap also seems to be degraded when exposed to longer boils (90-120 min). I recently did a batch where I over sparge by alot (though the ph and gravity wee all still above the warning area [1.018 and ph was around 5.5]). I ended up with about 9-11g of liquid for a 5.5g batch. I ended up boiling for roughly 4 hrs and had to add 2 additions of fermcap, since the first stopped after 90-120 minute mark.

The only thing I've used it for recently has been to keep my blow-off receptacle from foaming all over the place while I'm at work and crapping up my fermentation freezer.
Thank you BEER!
