Brewed a Brooklyn Brewing oatmeal stout over a week ago. Took a gravity reading a week after pitching their dried yeast (rehydrated and aerated) and saw krausen for a couple days after pitching. AFter that, I switched to airlock and never saw bubbles go from days 3-7. A week after pitching the gravity was 1.031. I figured it should at least be 1.020 a week after pitching. Don't know the yeast strain (they don't say) and I don't know the OG as I didn't take one on brew day (careless error). Added some harvested US-04, a few days ago and no airlock activity still. Did not make a starter, but I only have .8 gallon and I had 25 ML of yeast that was harvested less than two weeks after adding it to the oatmeal stout. The 04 was in the fridge from harvest date until I added it except for the several hours I let it warm to room temp. The oatmeal stout has been sitting at 67 degrees for over a week now. I've even gently swirled it a few times in hopes of getting the yeast going. Time to add yeast energizer or is this just a doomed batch for whatever reason?
