Minimize the loss on fermenting beer and transfer a slightly larger quantity in your existing fermenter. Our foam control is a vegetable oil-based antifoam. Proper use to control foam does not affect the head on your finished beer, and can actually increase the head by retaining head-forming compounds that would have been blown off during ferment. Vegetable oil is a known yeast nutrient and will be consumed by the yeast during fermentation of beer before bottling or kegging and will not blind filter media. Add 1 drop per gallon. Comes in a bottle with eye dropper. Good for about 50 batches of beer.
Our manufacturer adds that the amount of antifoam is a “rule of thumb” and the actual amount needed is determined by the brewing system used, the type of beer being brewed and type of yeast used for the beer. Higher original gravity beers like DIPA, big Belgian-Style Ales, and barley wines, for example, may take more; lower O.G. beers like Kolsch and light lagers generally take less.
