An anti-foam agent that can be used 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. It will not affect the finished beers flavor, appearance or head retention.

Can also be added during the boil to reduce the risk of boilovers. Use a few drops per gallon for boil, or two drops per gallon for fermentation.

Keep refrigerated until use.
