I just did my first brewday on Saturday. I made a partial extract caribou slobber kit because someone gave me an old one, the yeast was new though I got a new pack of Windsor at the LHBS.
I brewed in my mash and boil 2, mixed all the crap in, boiled for 60 minutes adding hops and all that, then pumped through a convoluted counterflow chiller into my conical's top port (spike CF10), its just under 5 gallons that was transferred (a little spilled when my hose blew off). One alteration I made to the recipe was to add water until it was 5.5 gallons and then boil down to 5 gallons instead of adding water at the end to make sure everything was sterile.
Another change which was probably a mistake since I should go simple at first was I set up the PRV and figured I'd see how high the pressure would get out of curiosity and because I was worried the room might get too hot during the day.
We pitched in the evening at around 70 degrees and the next morning it was at 6 PSI but I had a slow leak because I installed the gasket upside down, so I dropped pressure, reinstalled the gasket, and buttoned everything back up. Within a couple hours it was up to 10 PSI, and while the top was off I observed an impressive 4 inch or so krausen. The second morning it was at 5 PSI, and by the end of that day it was 0 PSI where it has remained. It is now the third morning.
Temp has been kind of erratic, should be 60-70 though, usually its around 66, targeting 68.
I'm guessing I should take a gravity reading to see how far it got before it stalled, but my question to you guys is, is it possible that all my pressure went away just because of suckback when the fermentation stalled or is this an equipment failure? That seems like a LOT of pressure to get rid of in that way. After I flipped the lid gasket there were no sounds to indicate that there was a leak so I'm not sure how it could be equipment failure. Since I started losing pressure I tightened the 15 PSI PRV all the way down so it shouldn't be letting out any gas. I don't have a CO2 cannister to test the system with, any ideas about how to test?
It seems like a paradox, if the pressure has gone down without venting it must have dissolved more CO2 but if it sits at 0 PSI won't the CO2 eventually come out of the solution?
