I picked up this strain because of its wide temp range. 1st batch went great and I saved a bunch of slurry. 2nd batch pitched a cup and a half of slurry and it was a slow bubble in a day and has been consistent since. started at 1.070 and 10 days in 1.030. When i drew the sample it was still too sweet and actual attenuation is only at 57%. Should I just let it keep going? It has a thick layer on top but the bottom has a real thick layer so it looks like it dropped out. Everything ive read on this strain which there isn’t much info out on it says it takes off but this doesn’t seem to have that characteristic at all. I know a starter would have helped. I’m lazy like that.
I’ve seen several people use this strain, like you with good success on the first batch, but I have seen far fewer results on a repitch. It’s definitely unusual that the yeast would underperform on its second round. Normally yeast acclimate better to beer fermentations in subsequent pitches.
I’d be curious to know more about your pitch on the most recent beer. How old was the slurry? Did you make a starter or aerate the wort? How warm did you ferment this? It may just be a finicky strain like 3724.
