First, the background. I recently picked up a used stir plate, and it
clearly has some circuitry issues. It has a speed control which doesn't
work above the "5" setting (speed flies out of control after that), and
it isn't supposed to be a hot plate, but boy, does it heat up.
The first time I used it I almost burned my house down. And that was
when I thought I had it turned OFF. Now, when I turn it off I also
unplug it, lest it burst into flame. When it's actually running, the
spinning rotor inside seems to move the air around enough to keep it
below, oh I don't know, 120 F or so.
The first starter I tried to make was destroyed, by cooking on the stir
plate after I thought I'd turned it off. Now I'm making another one,
and it seems to have survived its ordeal except that it fermented warm,
and by warm I mean like around 100 degrees. Not far beyond body
temperature, but definitely in that range.
Is this starter going to be usable, or will it turn my beer into a
hellish goo? Obviously, I'll decant as much of the starter beer off the
yeast as I can, before I pitch it.
