I have just purchased a 23 litre glass demijohn for fermenting my beers. I previously used a plastic fermenter and would cool using one of those stainless cooling coils, this would get it to about 50-60 degrees. I would then put into the fermeter and put in my fermenting fridge, pitching the yeast the next day. So my question is about the temp I can put the wort into the glass demijohn, I did some research online and it appears the 50-60 degrees temp would possibly crack it. What temps to people on here put their wort into the glass fermenter?
