I use a large % of Pils (Franco-Belges brand) in all my beers and do a 90min rolling boil (not jumping out of the kettle) to drive out the DMS precursors. I'm also paranoid during the initial chill down that the SSM/DMS (whatever) in the steam/vapor will condense on the lid and drip back into the kettle so I chill with the lid cracked a little.
The forum members have given good troubleshooting tips. Does the forum know if different brands/types of Pils have higher SSM potential?
