PB2 Posted July 4, 2007 Share Posted July 4, 2007 Firstly, it is nothing to do with using cling wrap instead of an airlock. Sulphur is normally a symptom of the yeast being stressed, more common with lager yeast. It dissipates over time. If you are fermenting with ale yeast, go for a temp closer to 20-21C and can you give us the details of your recipe? I recommend not to immerse anything into the brew. Had a case recently where the homebrewer was meticulous with cleaning, had replaced the fermenting vessel but still had a bad smell and taste with some of his brews. He sent a bottle in for analysis - it was infected and after a long discussion, he finally revealed that he uses an aquarium heater - bingo - the source of the problem.

PB2 Posted July 8, 2007 Share Posted July 8, 2007 Okay, Coopers Mexican Cerveza has a Lager/Ale yeast blend and it benefits from lower temperature ferments (21C or down to the 16-18 mark if you like). As said before, I recommend you don't immerse anything into the brew - that new aquarium heater is now second-hand and is an excellent source of infection.

kieran Posted August 7, 2007 Share Posted August 7, 2007 Yeah, if you're that keen to control temps, buy a 2nd hand fridge and go to mashmaster.com.au and get one of their temp controller kits. Then you can turn your fridge into a big brew incubator, and it will control your temp to within 1C. Works like a charm. You can also use it to control a lamp or whatever to heat it, if necessary. I did a nice north german styled lager this way.. (except I have a converted tuckerbox). Came out brilliantly. Link to comment Share on other sites More sharing options...
