Fermacap to help with Boilovers

I love this stuff, I add it to the boil and the carboy prior to fermentation as well. No issues or headaches!

One question, though, since there are so many Fermcap users/advocates here, I saw today that I left my bottle out, un-refrigerated for almost a week. Should I get rid of this and get a new bottle, or can it still be used?

 

I've never refrigerated mine. I didn't even know I needed to. Still seems to be going strong.

 

Older thread resurrection but a quick question.
When do you put it in. At the beginning or right when it starts to boil.
Or does it even matter?

 

not sure it matters, but i am in the habit of adding a few drops as the foam begins to build, right before rapid boil. it makes adding the correct amount easier. the prescribed "x drops per gallon" is misleading i think because it has the consistancy of Elmers glue. you just squeeze enough until the break drops and you're done. maybe a bit more if a hops addition causes some foam to rise.
Cheers.

 

I use as directed in the boil and it's amazing! I can push my 8 gallon kettle to the extreme. I did just have a 1# addition of Wheat DME with 20 minutes left in the boil that I needed some boil over control (lowering flame and stirring to settle the foam) but I have never had issues with hop additions causing boil overs.

I also use in fermentation to keep the blowoff in and not lose any of those necessary particles in the foam. Huge 12%+ ABV barleywine that fermented for a few weeks with only 1" krausen at high krausen! vs. 8% Impy Stout that blew off for days hours after pitching the yeast.

Edit: Supposedly it falls out during fermentation so there is no worry of carry over into the keg or bottle if you siphon carefully.
