I'm curious to know how many of you keep a lid on your boil - even partially. I've always brewed lid free to prevent DMS. The only time I keep it covered is as I'm coming to a boil to speed things up. However, I'm wondering if I'm losing anything (flavors, aromas) by brewing this way. Should I be keeping a lid partially on or anything like that? Just curious what everyone else does.

Also, I brew in my basement (with electric), so winds are not an issue for me.

It depends on the situation. With a good burner and in reasonable weather conditions it should not be necessary to partially cover the kettle during the boil. However, there is not anything wrong if your situation requires a partial cover as long as there is a good rolling boil and the majority of the surface remains uncovered to allow for evaporation of DMS presursors and other undesirable volatile fractions.

Sometimes I do, I have two elements in my kettle and I like to cut one when it comes to the boil, if it is very cold, i sometimes have to half cover the kettle to keep a good rolling boil with one element.

I say let the steam loose so you can smell your efforts.
