I am fermenting a porter with WY1450. I am going to give it a bit days to be certain but I have a bad feeling it's stuck at 1.022. I want a full body but not that full. I have read that you can rescue a stuck fermentation by pitching a higher attenuating yeast starter at high krausen. I was thinking of using some some US-05 to finish it out but I'm curious about one thing. Is there a way to calculate how much more my gravity will drop with the US-05? I just want to be certain it's not going to dry my beer out too much. I also have some S-04 if need be. I'll probably throw a starter together tonight and worst case scenario, if the beer begins to ferment again I'll just pitch it into something else.
Thanks for the help!
