Ferment temp

[Brownbeard]

I pitched my yeast into my Oatmeal stout last night at roughly 9pm. I have it sitting at 60 degrees right now, I am using Wyeast 1728 Scottish Ale yeast, which has a low end of 55 degrees. This morning, there was no action yet. I am wondering if it is too cold. I suppose it could be going tonight. This was the first time I did a starter, as well as the first time I used harvested yeast. I did the starter in a wine bottle, and there was about 1/3 of an inch of yeast on the bottom. I shook the yeast really well to get it all roused up, then hit the wort with the wire whisk for a while and pitched. It is probably bubbling away as I type.

I had question along this same line. My brewing closet stays about 62-65 degrees. I was wondering if I heated it up to about 70 if my fermentation will go further. I brew with extracts and get good activity with 12 hours but usually nothing after about 4 days. WOndered if I used a home heating pad under or near carboy would raise temp just a little or is it too hot to use? I read where you could use some kind of "lightbox" to heat closet, but I thought light was bad. I do keep carboy covered with one of my sons t-shirts.

Fermentation is an exothermic reaction and will generate some heat on its own. I have seen fermenting temps 5 degrees or so above the ambient temps so you should be good.

The time I would be concerned is when ambient is above normal operating range of the yeast and fermentation may creep into the mid-high 70's or better and produce some off flavors or to much fruity esters.

I got home last night and mine had about 1/3 inch of krausen on the top and was bubbling slowly at 60 degrees
I brought it into the kitchen, placed it next to the heater vent overnight, and this morning, there was a solid inch of krausen on the top and it was bubbling like crazy. I moved it back to the cooler spot, because I want it to ferment cool. That is why I chose the scottish ale yeast. It was still working a couple hours later. I did wrap it in an insulated flannel shirt.
