Well... maybe you can, but it's a lot harder than not using enough!

Just made an 1800 ml starter in a 2000ml Erlenmeyer flask, and only put in three drops/squeezes of Fermcap-S. I figured that would be enough.

FAIL!

Slight boilover, right through my foam stopper, no less. Cleaned up, put in five more drops/squeezes, and brought back to a boil.

Much better.

Please, for the sake of the stove and your sanity, don't skimp on the Fermcap-S!

-Steve

p.s. Did I mention that I really like Fermcap-S?

I just bought Fermcap-S and I have to say I love the stuff too. But i havent had any issues with boil over and found that if I use less, it still works great. I did an 1600 ML starter and boiling the wort in a saucepot (I have an electric stove) I put 1 drop in and had no issues at all. Usually I have to cut it down.

I also just brewed a batch and ended up starting with 7 gallons in my 8 gallon brew pot. I only put 6 drops in and it worked great. I still formed a nice hot break on top will about a 1/4in think layer, but no other foaming, even when adding hops.

Fermcap-S is by far my most favorite ingredient. When I do full 6.5 gallon boils in my 7.5 gallon turkey fryer I make sure to add about 3 full droppers. I have heard people use a lot less but I mainly add that much for peace of mind. Plus it isn't that expensive, so what the hell!

Lemme tell you a story....

Last friday I did a harvest of Hoegardaan yeast using the dregs of 11 bottles I recapped upon pouring and drinking the beer over a week. On suday I decided to feed it another batch of wort. I have a large earlynmeir flask, but clearly not a large enough flask for the blowoff I got when I came home from vintage baseball sunday evening, even blowing off the tinfoil.

After I cleaned off the outside of the flask and sprayed it ad a fresh piece of foil with starsan I hit the foam coming out of the neck of the flasks with a few drops of fermcap, and the harvest krauzen layed down and played nice...

Awesome stuff to have on hand.

I was at Captain Lawrence Brewery and they had like a 1 gallon container of that stuff... I was like hey i use that too!

Then I found out you can get it in up to 25KG containers...

3 full droppers???? I don't what the harm in overdosing is, but the directions are usually 2 drops per gallon, and most people get away with 1 drop per gallon without any reduction in performance.

25 kilograms *might* actually be too much... I don't think I could brew enough in a lifetime to use it all up!

I believe the problem is silicone is what is used to make the product work. You can ingest silicone in small amounts but its not good to overdose.

We sell the Five Star Defoamer and they say:
Usage: 1-2 drops per gallon. Do not exceed this dosage or your beer will exceed FDA limitations for silicon content.

I use a single drop in my 1L starters...I can boil like mad with zero chance of boilover. In the kettle, I stick to the 2 drops per gallon...although it's goopiness makes it nearly impossible to measure accurately.

But: Directions aside (which can merely be for liability purposes), where is there any evidence that the Fermcap-S is going to be in the finished beer AT ALL? I have read more than one thread that states that the Fermcap-S precipitates (falls out) of the wort or beer completely, whether in boil or fermenter, and is discarded with any trub / sediment. Has anyone seen any authoritative reference on this?

Note: Guess I didn't read the earlier post closely enough, which generates the next question: is the 5-Star defoamer the same product as Fermcap-S?

As for my use of Fermcap-S, 10 drops in a 6.5 - 7 gal boil does the trick, every time. This is a fantastic product for those of us who boil in 30 qt. kettles. I don't make starters, etc., so I can't speak to that application.
