Lager fermentation too cold?

Hey guys,
So my new brew spot is a little colder than I thought. Also a bit of a cold front happening right now. Anyways the ambient outside temp is 40 degrees. I checked on the stainless conical fermenter and the stick on thermometer is registering at 42 degrees. Have a spunding valve on and it hasnt produced enough pressure to register yet. The strain temp calls for 46 to 56. Do you think this is too cold?

Do you have a heating pad? Just enuff to get to 50*F. I’ll bet you’ll warm up naturally and the fermentation will take off. We do store yeast in a cold environment .

I do have a heating pad actually.

A heating pad would work with a temperature controller to monitor. If not bring it to a warmer spot let the temperature come up to the high end until fermentation starts. Then wrap in a blanket and bring it down. The fermentation temperature and blanket will keep it in the zone you need. It will slow as it cools but its still fermenting. After a week bring it up again for the d-rest for a day wrap then back down and lager

Ok I’ll try that. Im wondering how accurate the stick on thermometer is with a stainless fermenter

I just checked on it and its at 46 degrees and 5 psi so I think its rolling!

Have a thermapen? See if it reads the same as the stick on shtick…

Actually those stick on thermometer are pretty darn close

Yeh I thought about the thermopen. Im going to let this one roll and order a thermowell for the next batch. That will sit somewhat inside of the fermenter and then I can put a probe in there and have the temp controller set with a heating blanket or something. Kind of strange trying to keep it warm for a change, haha its usually the opposite.

The price of packaged brews has gone up quite a bit, so home brewing makes sense… again?

Well I checked on it before leaving on a trip for the weekend and it was at 40 with almost 15 psi built up. Added the electric heating pad that I use to use on buckets with some electric tape so I will see how it is tomorrow.

Alright its at 52 degress, 15 psi and bubbling away like crazy. 1 week (lager) later now.

Sounds like it’s rolling along… when it slows then start a slow warm up. Try 5*F and see if activity starts… couple days?
And repeat.

So the fermentation went fine. I only got about 3.5 gallons in the keg using the new conical. I think I need to aim for 6.5 gallons into the fermenter next time since I think the actual cone at the bottom holds a gallom or so before it even registers. Lots of trub amd sediment in there i must have dumped almost 2 gallond out. I didnt really mess with the rotating racking arm while I was filling it was angled slightly down toward the cone just didnt feel like moving it anymore once i saw some sediment enter the line to the keg i closed the valve and popped the ball lock off. Crystal clear beer otherwise though tastes great.

Are you saying you got more trub than usual in the conical? How long did you crash? This last batch I cold crashed (34F) a good week and the cake was pretty solid which allowed me to transfer wort without stiring up the trub. I probably get about 4.5 gallons from 5.5 in

My fermenter has a little bit of a dish compared to yours. I did cut the pick up tube off so it leaves about 1/2 gallon behind…. I really don’t mind a bit of trub… good B-complex vitamins for you!
