I asked on another thread about doing no chill and got a response that was quite different. They said that the "no chill" brewers had to boil for 90 minutes to make sure to drive off all the DMS precursors and that they had to be anal about sanitation. I don't see that you people are doing 90 minute boils so how are you not getting DMS? If you boil in the pot and put the lid on while it is still steaming, do you get DMS from the condensate dripping back into the wort or is a 60 minute boil sufficient? Do you worry about infection or does putting the lid on while the wort is hot steam pasteurize the lid?
