I was wondering about that. In my specific situation, I felt I had not other option to save the beer, because 1.030 just isn't palatable.
thanks for the info
Imagine an Oatmeal Stout, stuck at 1.030, then using AE to fix it successfully. Sounds very, very familiar Maybe you can get some more info from the following thread:
