FermCap-S Foam Control - 1 oz.

In Stock
60 day no hassle return policy. Details

No more boil overs, no more blow-off tubes. Once you’ve used Foam Control you’ll never brew without it again!
Foam control does just what its name suggests--it reduces foam production during  the hot-break portion of the boil, and it reduces the amount of krausen developed during fermentation.
Also known as FermCap S, Foam Control does not affect the head on your finished beer. In fact, it can actually increase the head by retaining head-forming compounds that would have been blown off during fermentation. It will settle-out of your beer before bottling or kegging as it is actually absorbed onto the surface of the yeast cells and filter media. 
Add two drops per gallon at start of fermentation. Comes in an eye dropper bottle for easy use. Good for about 50 batches of beer.
Note: Keeps best when stored in the refrigerator.

This stuff is fantastic in reducing the amount of foam during fermentation and actually also lessons the amount of encrusted foam you need to clean from your carboys!!

Can I re-pitch the yeast after using this in my kettle?
Philip Diehl on May 7, 2018
BEST ANSWER: Yes, you can pitch before or after fermcaps. Some use this to reduce high krausen and maximize fermenter space.

It works
This actually works. Add some to your wort before the boil and it will break the surface tension and prevent boil overs when adding hops.

I use a sintered stone and aquarium pump to aerate my wort and it sure stopped the foaming. I haven't tried the beer yet though.

Prevents boil-over like a champ. Less effective during fermentation.

I put two drops into a 5 gallon ferment that was looking like it would foam over. About 15 minutes later the foam had reduced and no foam over.

Worked Excellent
Boiled 18 gallons in a 20 gallon kettle and had literally no foam! Will be using on big batches from here on!

This can be added in the fermenter without adverse affects to packaging.

No more boil overs!
I boiled 8 gallons of wort in a 15 gallon kettle, and this stuff works like magic. Barely any surface foam. Planning on doing a 10 gallon BIAB batch in the same 15 gallon kettle, starting with 13.5 gallons of water, and I would be highly confident of no boil over. Can't wait to use it for yeast starters!
