Mashed way high, unfermetables?

Good morning HBT,

I brewed a batch of JZ’s Oatmeal Stout which came in at around 1.058. I believe that I mashed way too high because I used a new thermometer; I did calibrate with ice water… but didn’t check against boiling water until a week or so later and it read ~206º. My best guess is that the mash was at around 160 or so...

The batch was pitched with Safale S-04 and fermented at around 65. So now, 2.5 weeks later the gravity is only down to 1.024. I have warmed the fermenter, swirled and stirred, and repitched with Safale S-05 (last week). No gravity change.

Does anyone have any other ideas, or should I just go ahead and bottle the batch and put them all in garbage bags in case they all explode? Thanks for any suggestions!

That may be all you are going to get, S-04 isnt a very high attenuating strain anyway, and if mashed at 160F you will have some unfermentables in there. If you have warmed it, swirled it, re-pitched with US-05 and the gravity is not budging, IMHO it is done.

 

Does it taste cloyingly sweet though? If it's not what you really wanted, now might be a good time to brew another batch, mash low, and blend.

 

Not really cloyingly sweet that I remember, I'll double check with a hydro sample.

Thanks for the great idea... I might just brew another batch and blend!

What did you decide to do? I have about the same situation here. Mine's not cloyingly sweet, it actually tastes pretty good. I think I'm going to bottle mine sometime next week, stick it in a Rubermaid tub, and hope for the best.
