Pressure Transfer Question

[jonheather2010]

Hey all,

I ferment in a 14 gal conical. I happened to purchase the leg extensions for it so the racking port is higher than my keg. On kegging day, I just put my keg underneath the racking port and gravity fill. Could I still benefit from pressure transferring because O2 is being sucked into the fermenter via the blowoff cane to replace the exiting beer (and therefore my beer is technically coming into contact with O2 and it isn't a true closed system)?

suppose it wouldnt hurt. Just toss your tank on there and hit it with 1psi and let it basically gravity feed. But the amount of O2 that comes into contact with the beer from being sucked up the blowoff is negligible, so I probably wouldnt worry too much about it.

Yes, pushing CO2 in where oxygen/air would normally draw in is a best practice for ALL activities involving anything coming out of the conical. Trub dumps, yeast dumps, sampling, etc.
