I might have to start fermenting Ales 

Has hell frozen over?   

I think it may be on it's way. 

Just can not take a pressure any more...

My last hell(es) did freeze over.  Wish I'd thought of this pun, could have named it so!  fortunately the beer turned out fine after it thawed and finished lagering.

funny...didn't think of that one.

Sorta along the same vein . .

What's everyone's experience as far as lager exothermic increase during active fermentation? About the same as ales? In the past I set the ferment chamber 3 to 5 degrees lower to compensate for what I guessed was going on inside the fermenter. Now that I finally have a thermowell, I guess I'll find out for sure!  Just curious on other's experiences.

I do have temp probe on the fermenter so I do not know.
You are growing less yeast so In theory would not you generate less yeast?

I also have a thermocouple attached to the side of the fermenter.  This will keep any exothermic temp rise in check.
I'm not sure how this will effect the yeast growth but I think it helps keep the clean lager character in check.

I wanted to say:

I guess I should read what I type

Maybe I didn't express myself clearly. (which happens a lot) Experience has shown when fermenting ales, the temperature inside the fermentor can be anywhere from 5 to 8 degrees warmer from exothermic processes than the surrounding ambient temperature during the active fermentation stage. I was curious if that is what folks have found to be the case with their lager yeast as well.

[bluesman]

Never measured it but I think it depends on OG, yeast strain, ambient temp, etc..

As above, and the fermentation is going half as fast so I would assume half the exothermia?

Agreed it's not working as fast therefore it's not sweating as much.

Like I said . . it is mostly a curiosity thing since I now have a thermowell and can find out for sure myself!  I'm 34 minutes away from flameout on a PU clone and the ferment chamber is sitting at 48 degrees. I'm gonna throw a digital thermometer in the chamber and see how much difference there is between it and  the fermentor's bowels when it gets going.. I WILL report back!

Look forward to your findings!

Look forward to your results.  I use the temperature outside of the fermentor, not "in it's bowels" via a "Low tech lagering System".
