I just added an additional 100g of dry hops to the FermZilla and noticed that it will self flocculate for 10 minutes after releasing pressure then adding the dry hops. By releasing the pressure the CO2 release causes the liquid to roll around in Fermzilla for some time, additional charges with your CO2 cylinder followed by a dumping through the pressure relief valve will initiate the flocculation again. Ive done it 3 times now and it works like a charm. I will add that i removed the Trub through the collection container the night before to minimise the amount of trub being agitated through the aforementioned process. Just make sure you release all pressure from the vessel prior to removing the bottom collection container! The female thread on the Fermzilla collects alot of trub so be sure to spray it clean and sterilise before reinstalling the collection container, then purge the container of oxygen prior to opening the butterfly valve. Although it appears that you'll lose 1L of beer which drops back into the container after dumping the trub, my container is quickly filling up with hops following precipitation into the container therefore it should displace the beer back up into the fermenter where it can be sucked up...This all makes sense WEAL, but will take away 1 of the things I was really looking forward to with using this Fermzilla, which is rousing up after my dry hop additions to get full utilisation out of this dry hop process. My plan was to dump the yeast after fermentation is basically done, and then replace the collection bottle with the dry hops which have been purged with co2. After a few days hook up the co2 to the collection bottle via a carbonation cap/post and rouse the hops off the bottom and get them flowing about again.
I guess I could leave the yeast in the bottle, dry hop through the top & rouse co2 through the beer out post & dip tube. Has anyone done this with the version 1? Would it disturb the yeast too much?
P.S. I love our man Jasper! Keep Drinkin'!
