I'm in the same boat. Made an extract irish clone batch 20 days ago, and the initial fermentation kicked off fine. I used about 45 sec of 02 through an airstone, but didn't shake (this was my first time using an 02 setup). Fermentation was going strong the next morning before work... Never got an OG due to my wife cleaning out the brew pot before I could get to it. A week later, the SG was 1.032 according to the refractometer. I moved it from the 62 deg basement to my office which is a bit warmer, and shook it once a day for the next few days. A week after that, SG is still 1.032, and still is now.
For re-pitching yeast - do I just make another starter (I used dry yeast rehydrated), and pour in, or should I step it up w/ sterile wort a few times? Should I re-oxygenate as well? I can't RDWHAHB since it's all been drank except for the gluten free batch... Thanks!
