Hello everyone.
I am making a stout. It has been in primary for 9 days. The OG is 1.079 and as the subject says, I used the Wyeast 1728 yeast. It has a 69%-75% attenuation and suggested fermentation temp is 55-75*, which I have been fermenting at 66*. I made a 2000ml starter with yeast nutrients on a stir plate and used an aquarium pump for 30 with a hemp filter for 30 after the wort was down to 67*. I have been checking my gravity and it appears to have stopped. I have a chest freezer with temp control so I set the temp to about 70*, still under recommendations. I also swirled up my carboy to get the yeast back into solution, but there are now bubbles coming out of the airlock, probably the yeast fell back out and/or it is still at 66*. What else can I do?
Thank you in advance.

Just what is your gravity right now? Depending on your recipe (is this an extract batch?), this beer just may finish out at around 1.020-1.023.

The bubbling you are seeing right now is most likely CO2 coming out of solution as a result of rousing the yeast. At low fermentation temperatures like you are using the yeast will work more slowly so I would let it go for at least another week. Since the fermentation is mostly done, raising the temp to 70° is no problem at all and may speed things up a bit. I would also advise against racking it yet (if at all) and wait at least 3 weeks from brew days to bottling.

Your process looks great and I wouldn't change it for future brews. I also ferment most of my beers in the mid to low 60's. All you need is some more patience.

Merry Christmas

Right now the FG is 1.041 and that is only 48% attenuation. That is why I started to worry. I know... I know... RDWHAHB.
