RandB Posted September 28, 2006 Share Posted September 28, 2006 I bought the Coopers homebrew kit and I was wondering how accurate the theremometer is that you stick on the side of the fermenter barrel. It appears to be about 3 or 4 degrees hotter than the ambient temperature. Does this mean that, due to fermentation, the brew warms up slightly?? PS I have done the lager that comes with the kit and a Canadian Blonde with honey. Can't wait to taste them. Link to comment Share on other sites More sharing options...
PB2 Posted September 29, 2006 Share Posted September 29, 2006 The temperature strip is reasonably accurate +/- 1degC. Yes, it is measuring the temperature of the brew. The brew may be hotter or colder than ambient - keeping in mind that the body of fluid will have some thermal inertia. Yes, fermentation is an exothermic process but the brew is not likely to heat 3 to 4 degrees above ambient. Link to comment Share on other sites More sharing options...
capretta Posted October 1, 2006 Share Posted October 1, 2006 hey, just my 2 cents but i have found 2 or 3 degrees above ambient at the height of the fermentation to be quite normal for me. one brew i did where i pitched 2 packets of yeast at 28 degrees then covered with towels as it was quite cold (18 degrees ambient). one day later i was horrified to find a very vigourous ferment and a temp of 32 on the keg! needless to say, quite a funky tasting brew, :oops: all a learning curve!!
