- Nov 29, 2006The heating problem seems to be worse when I do a corn/barley mash. The rising CO2 pushes the crushed grain up forming a sorta insulating cap on the mash. I usually punch it down several timed a day. Seems to solve the problem.Dave H.----- Original Message -----From: donald holcombeSent: Tuesday, November 28, 2006 9:11 PMSubject: Re: [Distillers] Re: youtube videoI never paid any mind to the temp rise in the fermentor till I joined this group . I have since found it can be quite a noticable rise. I guess thats why we never made drum size batches till fall. LATER----- Original Message ----

The main problem with large ferments is the mash temperature. Most
distilleries will have cooling tubes in the fermentation vat to keep
it constantly at the optimal fermentation temperature. Generally they
will set it to ferment at the fastest rate they can without killing
the yeast. However, this results in more fusel oils produced.
Fermenting at lower temps produce less fusels, but they also take
longer. Much longer than 60 hours.
