Thanks. As if regular brewing wasn't complicated enough...

Very interesting. Thanks for the initiated analyses and references. I will burp some artificial CO2 into the vessel tomorrow and see what happens. Or maybe rather when the vessel is empty, to rule out any other parameters than leakage.

Another interesting discussion. With forced carbonation in kegs (as I normally do), you can't just crank the pressure up to the desired level for a couple of days, turn it off and be done with it. You have to continually add gas for many days to reach equilibrium at the target pressure. I...

OK. Maybe I'm reading too much into the data. I'm eager to understand possible effects of pressure fermentation but this is probably unrelated to that, then. I do, however have questions about the usefulness of pressure fermentation if the pressure drops to less than 0.1 bar after the...

Yes of course. But gradually (asymptotically). Not abruptly like this. Granted, my experience with 34/70 is limited. Maybe it is known for behaving wierdly?

"Concerned" is too strong a word. I can live with 1.010 as FG. I'm wondering about the sudden and definitive halt of the fermentation. I'm regulary recording my fermentations with my TILT and I have never seen a curve like that. Two more days now and still bang at 1.010.

Well, I reckon the beer gradually absorbs CO2 and if no new CO2 is added, the pressure drops (to the point of equilibrium). At least that's how it behaves in my kegs.

Howdy! My first attempt at pressure fermentation. Got myself a Fermzilla 30L All Rounder with a spunding valve. Brewed a German(-ish) lager in the usual way. Pitched 2 packs of 34/70 at 10 °C and let it ride with no pressure for the first 3 days. Set the spunding valve at 0.8 bar on day 4 and...

Roughly Valves: 20$ JG couplings: 30$ Switch, LED, terminal blocks: 15$ Power adaptor: 10$ TOTAL: 75$ And yes, it's tempting to turn the switch back and fourth frantically and persistently while pouring a pint. A world of new discoveries:ban:

On reflection, there's probably a larger volume in the shank than in the tube. This is hard to avoid...

It's pretty minimized as it is. The residual volume is just in the 60 cm tube between the "hub" and the tap. A few ml. I could of course move the hub very close to the tap, but that would require four tubes all the way there whitch would defeat the purpose of reducing tube hassle. If I had...

Hi folks! Long time lurker on this exquisite board just wants to share this humble low-tech construction of mine. Two years ago when I was decieved into homebrewing, I had no ambition to become any kind of equipment or DIY nerd. I felt quite content with stove-top BIAB and carbonating in...
