I recently brewed 2 separate batches of Oatmeal Stout a week apart. Both of them are now stuck at 1.030. There were a few changes that I made with my procedure but I do not see how they would have affected it this much.
1.) Mashed too high. I mashed around 160 since i had a new thermometer that I did not calibrate before use. I could see this adding to the FG, but I do not know if it should have been that much.
2.) Grind my own grains. I purchased a monster mill and ground my own grains. I left the settings alone and I had A LOT of powder so I think the teeth are too close together. I also got a lot of trub afterward which I believe is from this.
3.) Did not use PH 5.2 stabilizer. I also did not check my PH at all, but I did a full volume (almost 8 gallons) BIAB and the recipe came out at 1.058 for both which was almost 80% efficiency. I was getting 70% before with store ground grains.
I did just place an order for amylase as I have already tried to rouse the yeast, added yeast energizer and nutrient, and raised the temp to 72 (I fermented right around 66). I did re-pitch a 1L starter of Nottingham a week or so ago and nothing happened.
I'm open to suggestions. Thanks in advance.
