Hi all
I use the Fermzilla as my fermentation vessel, I do not use it (yet) for pressurized fermentation but use the included airlock.
Next week, I'm going to brew a NEIPA which includes dry hopping during the last 3 days of fermentation. Since this beer style is very sensitive to oxygen I want to avoid introducing oxygen as much as possible.
Will I introduce oxygen if I simply remove the collection jar at the bottom of the fermenter, add the dry hops, purge the jar with CO2 and reconnect to the fermenter? Or is there a chance the fermenter might suck in oxygen through the air lock when doing this?
Or would it be better to pressure ferment straight from the start? I have a spunding valve but not yet the gauge to measure the amount of pressure in the fermenter, which is one of the reasons why I haven't tried it yet.
Thanks!
Gilles
