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.
