My last batch on my HERMS, I hit my OG and measured with a refractometer of 1.065(1 degree higher than expected). My mash efficiency was 73%(first time BIAB). I felt great that I hit my OG using the method of BIAB for the first time.
I used OLYMPIC Irish Ale Yeast for my Oatmeal Stout. I cooled down (and maybe not cool enough and this is where I went wrong) to 82F and pitched the yeast(No starter since it was a 5gal batch and the yeast had manufacture date of about 3 weeks prior). I put it in my fermentation chamber and set it to 67F. The fermentation took off in under 12 hours and things were going good. After about days it really slowed and I checked the gravity and got 1.038 with the refractometer. What? I am expecting 1.020.
I roused the yeast and set the temp to 69F. Btw, I am using a bung with the thermometer tube and an Ink Bird.
2 days later, I am still around 1.037.
Did I stress the yeast out too much from my initial pitch? Should I have made a viatility starter even though the yeast was only 3 weeks old? These manufactures say all you need is one bag for 5 gal...I guess we can't trust that?
Thoughts, ideas on what to do now or future?
Thanks!
