When it comes to preventing boil overs on the hot side of brewing, FermCap is a fantastic solution. It works by reducing the surface tension of the liquid, which helps to prevent the formation of foam and ultimately boil overs. To achieve the desired effect, it is recommended to add 2 drops of FermCap per gallon of liquid during the boiling process.
Adding FermCap to your boiling wort or beer not only prevents boil overs but also helps to create a nice rolling boil. This is important as a vigorous boil promotes proper hop utilization and evaporation of unwanted compounds. The addition of 2 drops per gallon ensures that you have the right amount to achieve an optimal boil without any excessive foam or overflow.
Moving on to the cold side of brewing, FermCap is also useful in controlling the krausen during fermentation. Krausen is the foamy layer that forms on top of the fermenting beer, and it can sometimes rise to the point of overflowing from the fermenter. FermCap helps to keep the krausen in check, limiting its height to around 1/2″ in a 6-gallon carboy.
To use FermCap during fermentation, it is recommended to add only two drops per gallon at the start of the fermentation process. This small amount is sufficient to control the krausen without affecting the overall fermentation process or the flavor of the beer.
One of the great advantages of using FermCap is that it eliminates the need for blow off tubing in a 6-gallon carboy. Blow off tubing is typically used to redirect the excess foam and krausen that can occur during fermentation. However, by using FermCap, you can avoid the hassle of setting up blow off tubing and the risk of potential contamination.
It is important to note that the recommended dosage of FermCap is two drops per gallon for both boiling and fermentation. Using more than the recommended amount may not yield any additional benefits and could potentially impact the flavor of the beer.
In my personal experience as a brewer, FermCap has been a valuable tool in preventing boil overs and controlling krausen during fermentation. It has provided me with peace of mind and allowed me to focus on other aspects of the brewing process without constantly worrying about potential spills or overflows.
FermCap is a reliable and effective product that can be used in both the hot and cold sides of brewing. By following the recommended dosage of two drops per gallon, you can ensure a smooth brewing process and achieve optimal results in your beer.
