I tried adding gelatin for the first time to a already carbed keg that just wont clear up. Its a smoked amber, that is as cloudy as a hefe. Sounded like gelatin would clear it up in a couple days. I added it 5 days ago to a cold keg, and it looks exactly the same now as it did before. How does the stuff not work? I added it warm, just dumped it in, didn't stir it.
