Fermometer
JS
plastic strip called the Fermometer, which monitors actual temp of
fermenting beer. You don't need to expose the adhesive on the back;
you'd be stuck (pun intended!) with it where you placed it. I use
cellophane tape at either end, and can easily transfer it between
vessels. While growing a starter in my 1ltr. flask, I noticed the
wort temp was about 2 degrees F. higher tham ambient. Now I have my
Better Bottle with 5 gals. of NB's Irish Red going full krausen in the
basement, and damned if the temp reading on the strip isn't 2 degrees
above ambient, that is, 61 and 59 respectively. The only thing that
surprises me is that the differential is not greater. After hearing
that active ferments can be up to 10 degrees above ambient, I'm rather
surprised that with a 1-inch head on top, the temp is only 2 degrees
above. Yeast is the recommended WY1272 American Ale II.
No real question here --- just thought I'd share my observations and
invite comments.

It depends on the ambient temp. The warmer it starts at, the more active
the fermentation will be, and the more heat it will create. Your ambient
temp of 59F is pretty low. I bet if your ambient was 70F you'd see a lot
more than 2 degrees extra, probably more like the 10 that you heard about.
Typically, my ambient is in the low 60s (62-64) and I get 3-4 degrees
of additional heat in the fermenter.

I hope this answers your questions, John.
If not... yeast ferments at its own pace. Some ferment faster than
other and generate more heat than others. The actual temperature that
the yeast is fermenting will also help decide how much heat it
generates.

For one thing, plastic is a much better insulator than glass or
stainless. There may well have been a greater difference in
temperature. The Fermometer just didn't see it.

Hmm, I recall on the Jamil Show, on the Brewing Network, they talked
about glass vs plastic regarding getting a temp read from outside the
vessel, and he pointed out that the walls of plastic fermenters are
quite thin compared to glass. I would tend to think that would tend
to equalize things. You may have a point, tho.
