Should I ad additional yeast?

[UglySister]

Wyeast 2124 is fermenting slow. After 10 days of fermentation it has slowed to 2½ minutes between bubbles. (temperature is 53°) I don't know what to expect as FG. OG was 1.040. I'm wondering if I should add another yeast pack or just wait for it to finish.

Have you taken a gravity reading? It could be done and still have occasional bubbles in the airlock.

I haven't taken a reading yet. What should I expect for an FG? It was 9 lbs of 2 row and 1lbs of carapills.

What temp did you mash at? And I can plug it into beersmith for you.

153° 75 min / 167° 10 min

I put the OP's grain bill and yeast into Beersmith and assumed 152° mash temp. Came up with 1.052 OG, 1.014 FG.

Current gravity is 1.012
I racked to secondary and put it back in the basement. Hopefully it will drop a little more.
I had extra so I filled a growler. Was that a bad idea?

6 gallon recipe (Those numbers are 5 gal I'm guessing)

Did you raise the temp into the 60's for a few days to do a diacetyl rest? Lager really needs some time for yeast clean-up, several weeks on the yeast.

That would explain the lower OG.

No, I don't have access to 60°. I could bring it upstairs put in a closet. (70° daytime / 65° nighttime)

yeah probably is i got 1.054 with my equipment and 5 gallon batch.. with 6 gallons i get 1.043 og and 1.011 estimates at 150F.. so your not doing to bad...

 

[helibrewer]

You've racked it off the yeast already so I would just give it a couple weeks now....you can sample it to see if you can taste any diacetyl (buttery, buttered popcorn like taste)

Do you think the growler will naturally carbonate even without bottling sugar? Is it safe? I don't want it to blow up.

Growlers aren't made to hold much pressure, seems a bit risky
