Was mine just defective or what?
Clearly. The stuff I got from Morebeer is like night and day. I can put it in the boil kettle and literally go have a nap. NO chance of boilovers.

Or perhaps you forgot to shake it up REALLY well?

This stuff is amazing! I have never used it in my kettle but I use it in all my fermentations. I can now add more to my fermentors and get a solid 5 cases for every 10g batch! I can also vouch it does not effect flavor or heead retention!

A great start would be here:

I use it on all hot side boiling including my BK and my erlenmeyer when making starters, I have a 15 gallon pot that I fill to the brim with 13.5 gallons of wort and hit it with fermcap-s and go eat lunch and come back for the 60 minute addition (90 min boil).

My LHBS recommends StillSpirits Top Shelf Distilling Conditioner (Defoaming Agent) to minimize boil over. This product works great but I am somewhat apprehensive about putting Silicone into my beer. The ingredients are Silicone and propylene glycol and I think it is designed for distilling, not brewing.

I used about 1/2 capful (1.5 mls)/5 gal in two batches. Have I poisoned my beer?

Thanks for any input.

Has anyone experienced a decrease in how vigorous of a boil you get when using fermcap? It does not make sense that it would cause the actual boiling to decrease, just the foam.

The major cause of foaming prior to the hot break is due to the protein not being fully coagulated. Once the colloidal protein coagulates and drops out in the hot break foaming is less of an issue. Since copper can hasten the process, I simply keep three or four pennies around by kettle. If the foaming becomes too intense I throw the pennies into the boil and watch the foam recede. Works every time and the pennies are reusable.

I start my boil and watch for when the foam starts to rise. At that point I start adding drops of fermcap until it drops back down. At that point I can get a nice vigorous rolling boil with no boilovers.

I've used it a couple of times in my beer and never noticed any off-flavors and it really does the trick in a turkey fryer when you only have maybe 1 inch of pot above the wort.

I've also had some brewing sessions where the boil just seems to behave itself and the drops were not necessary. Haven't figured out why exactly yet.

I did a stout a couple of weeks ago with McStout and we used gas drops from the store. Tamed the wild foam. We'll see soon how the flavor turned out.

And as an FYI, I boiled a small amount of wort separately on the stove, and that did not get the drops. The 2 quarts of beer that did not get the drops developed a LOT of krausen. My very quick peek into the bucket of the stuff I used drops in seems to have little to no krausen marks. I am thinking that the stuff managed to get transferred into the fermenter from the kettle, as I no-chilled the kettle outside in the snow and poured it through a strainer going into the fermenter.
