Hi Terry
When I was brewing a number of years back (before I took a break) I used Boots PBs for some beers. What I noticed was that after the initial carbing up of the PB some beers were slightly hazy. However there seemed to be a stage/pressure below which the beer would clear almost overnight after I had drawnn off a pint or two the previous evening. I could never understand why this happened. I have since used PBs in the second part of my brewing 'career' and never noticed this again. Anyway perhaps @That_Steve might have the same. Anyone out there who can offer a solution to this odd phenomenom?
... ok, I'll have a go
Hi Steve
I did half wonder (although looking back I expressed it extremely poorly in my initial post) whether with the internal pressure/carbonation, opening the tap was causing the inside to kind of fizz up like a coke bottle (other brands are available) and thus stirring up the sediment.
... I think some of that may well be happening ... and you need to recognise the chances of that happening (whether in a pop-bottle or a pressure barrel) will be increased by a combination of the pressure in the vessel and the numbers of "nucleation points" in the stuff in there ... you haven't mentioned what sort of kit it was you made and what sort of yeast was used, but if it was a "fluffy" (low flocculating) yeast (like say US-05), and if you're not storing that vessel in a particularly cool location, then you may well be finding you're creating the "ideal conditions" for that to happen whenever you're opening the tap
... and even worse, each time you open the tap, you kick up a load of yeast sediment (creating a load more "nucleation points") and increase the chances of it happening next time
... so what can you do to "break the cycle"? Basically, leave it alone to condition, stop sampling it and get it somewhere cool (which will both increase the amount of CO2 that will dissolve into the beer (reducing the internal pressure) and encourage the yeast to flocculate (to a more compact yeast cake, reducing the number of "nucleation points").
My guess is that what Terry found, and what you will find, is that as you become a more experienced brewer, you gain confidence (and rolling stock) and leave the brew to condition better (for longer, cooler) before starting to drink it, and by then the yeast will have compacted sufficiently to be able to draw off a clear pint ... alternatively, you take Clint's advice and get on with drinking it and it'll be murky until it gets to the point where you've drawn off enough to reduce the internal pressure and waited long enough for the yeast to settle enough, to be able to draw off a clear pint
