Fermcap-S Foam Inhibitor - 1 oz.

Anti-Foam Drops Minimize the loss on fermenting beer and transfer a slightly larger quantity in your existing fermenter.  An anti-foam agent that can be used during the boil or during fermentation to eliminate messy blowoff. As soon as fermentation is over, this insoluble compound settles out and remains behind when the beer is racked.

Keep refrigerated until use.
