Default Ferm temps too low?

So, I've scoured the threads, and I'm still left with a question. My active fermentation is fine. However, after that, my fermentation vessel and beer usually hover @ 60-62F -probably 58-60F at night. Do you think I'm getting enough residual fermentation going on, or is the remaining yeast just going dormant?

All yeast has a temp range which you can find on the package or online. As long as the fermenter is in that temp range everything is fine. And the lower in the range, in most cases, the better.

Thanks for the response. Anyhow, I know the best temp ranges for this yeast. I just was wondering about the drawbacks of it being under the low side. I don't have a lot of options for warming it up. :/

As it falls below the recommended temp the likelihood of it falling out and leaving an unfinished job increases.

That's where some sort of thermostatically controlled heat belt or other comes in handy. Keep it from dipping too low.

The drawback is that the yeast can go dormant, at some point below the bottom end of the temp range is the point the yeast will go to sleep until warmed back up.

There's always options to warm a fermenter up, they just haven't occurred to you yet.

Wrapping a blanket or sleeping bag in is good for a few degrees.

Putting a carboard box over the fermenter.

Move it to a warmer section of the house.....like against a sun facing wall.

Do you have hot tap water? Do a reverse "swamp cooler," put your fermenter in a larger container and fill it with hot tap water instead of ice.

Wrap a blanker around it then wrap it in christmas lights for an extreme example.

Put it near the furnace/water heater.

Put it in the closet with a ceramic heater.

Put a heating pad under it (but be aware that some modern ones have a timed shut off. Go to a salvation army or junk store and try to find an older model without one.)


Told ya...

(These are all options without using a temp controller and a heat belt.)

I may use a fermenting carboy as a Christmas tree this year. Thanks for the idea, Revvy.

You need to make sure you wrap it in something to block out the light though. I'm not sure how having a light source that close would affect the beer. That's why I suggested wrapping it in a blanker (or sleeping bag even) first.

HA! Reminds me of the idea we had last year. Put green rolling rock bottles on my red bottle tree,then my son inserted some mini lights. Voila! Red neck Christmas tree centerpiece! And I saw the Christmas light thing on craigtube before. He put them in a small dunnage container with the bottled beers so they'd condition properly in a cold Canadian basrment. I imagine a cardboard box around the fermenter with the lights would do it.
