Hi,
I'm trying to get away from bottle fermentation. I have a Fermizilla and bought a counter pressure bottle filler. I don't want to deal with kegging right now either. I also don't have a good way to cold crash right now which is ok because the beer is crystal clear.
This is a Brown Ale that I would like carbonated to 2.3 vols. I did not ferment under pressure this time because I wanted the ester production. Frankly the WLP005 yeast was about done in 24 hours so it would have been hard to time slapping on the spunding valve for the last four points of gravity.
My plan is to carbonate in the Fermzilla. The temperature is 65 F. The bottles will be stored at 65 F. According to online calculators, to get to 2.3 vols at 65 F I need to pressurize to 23 PSI. From what I can tell, that should be safe for the bottle and once cooled in the fridge, that pressure should go down as more CO2 is dissolved in the beer.
All the videos on counter pressure filling have people using chilled kegs and bottles often around 12 PSI (depends on beer type). I do wonder what happens when those bottles warm up and CO2 comes out of solution (bottle bombs?)
If anyone has done this, what are the lessons learned? Once the beer is chilled in the bottle, because more CO2 will have been absorbed, will I have issues with head or foaming? While people talk about chilling the keg and bottle before counter pressure bottle filling, isn't it mostly about having the beer and the bottle at the same temperature to avoid foaming? I can see a chilled bottle encouraging some more CO2 to be dissolved and ensure the reverse process doesn't happen. The Fermzilla handles up to 35 PSI, so pushing it to 23 PSI seems ok, but it makes me nervous since most of the videos on line talk about 12 PSI give or take (but those guys have the Fermzilla in a fermentation fridge at 45 F after cold crashing).
Help me avoid any more big mistakes. I did my first brew with a Brewzilla Gen 4 and it was a s4it show, but hey, I still got beer in the end and it came out pretty good!
