In a moment of laziness, I transferred some finished beer into a keg that just kicked without cleaning and sanitizing the keg. All is good. I have no fear of contamination and the beer that was in the keg was from the same batch as the one going in. There was some trub in the empty keg from the first beer and I siphoned a little more from the fermenter in the process, but it was fairly clear beer.
I carbonated the keg by shaking under fairly high pressure, which is my normal method.
I had used gelatin to clear the first beer in the keg.
Do you think that the remaining gelatin in the keg from the first beer will clear the second beer?
I guess time will tell, but it seems to me that this should work.
I normally put the warm gelatin into the bottom of an empty keg and siphon on top to get good mixing. So I think it could work except that you might have pumped a good bit of it out in the first pint or two . Maybe not. Maybe use a lesser amount ?
Several days and several pints later I’d have to say it didn’t work. The beer is still fairly hazy. My guess is that enough of the the gelatin got pulled from the bottom of the first keg’s use that there wasn’t enough to clear the second beer. Or maybe Narvin’s theory about jello, but I’m not sure that’s how it develops.
on the commercial side we’d use 180 F water from our HLT and add it at around that temp to cold crashed beer to give it one last clearing. We always had good results. I can’t remember what our h2o - gelatin ratio was but something like maybe 1/2 lb to 1 lb for a 15 bbl batch
