diacetyl rest activity?

[MacGruber]

Hey guys,
I have an oatmeal brown that I took out of my kegerator for a diacetyl rest. I used Londen ESB ale, and a full diacetly rest is recommended. It's been in primary, in the kegerator for 3 weeks. It's been out overnight and my house is 78 degrees. It sounds like it's going crazy and fermenting again. Please tell me this is just off gassing from taking it out of the kegerator. I don't have a wine theif and I'm leary about opening the fermentor to take a hydrometer reading because I don't want an infection. I think it's the only way I'm going to know for sure though. Does this normally happen though?

Yes, if it's going from the kegerator to 78 degrees, there will be lots and lots of off-gassing as warmer temperatures release far more dissolved co2.

Just took a sample and it's at 1.020. I guess it's definitely time for the rest. When I tasted it, it had a slightly fruity taste, almost like faint apples in the background. Overall, it tastes pretty good. We'll see what the rest does for it.

I remember this happening with my first AG batch, a Noble Pils. You were also the one who helped me through that stressful process. Thanks again!

Glad to help!

78 degrees is pretty darn warm, so I'd try to keep it under 72 or so if possible. We're having a heat wave here (well, just about everywhere in the US, I guess) so it might not be easy to do, but I'd give it a try.

Will it make a huge difference at this point? Will it produce fusel alcohol during the diacetyl rest?

I used wyeast 1968 esb. In a brown ale and it finished out at 1.020 as well I didn't don't any rest and it came out good

Did you get any diacetyl, buttery flavors, or slick mouthfeel from the 1968? How about acetylehyde? Did you have a fruity, apple taste?
