We currently brew about 120 gal. in 170-180 gal plastic frementors. There is a 2 foot head space between the final beer volume and the top of the tank once the knock out is done. Based on what our yeast guys tell me about the psi of O2, time of aeration and amount of yeast to pitch- these variables cannot change. My issue is that by the next day the tank is so active that I've lost about 10-15 gallons of beer from blow off. Any suggestions???? I can try an add a blow off but feel this will not amount to anything other then not having to clean up the mess after, instead of flowing out the top it will just flow out the tube.

Know that the Patcote is a vegetable oil based antifoam and not silicone based like most. Thats how you can get away with it in unfiltered beers. Granted the silicone works better but I dont want that in my beer. Dana says the yeast will metabolize some of the oils and we have never had head retention issues because of it.

Ive used it in 3 batches. 40ml at the end of the boil. So far everything seems to be working with not tanks overflowing. Its also much easier to clean the tanks because it has not spilt over the covers and blowoff. Next week I will xfer the first batch so I dont have any results for head retention, but from what everyone is saying this is not an issue.
