Boiling 101

When boiling the wort, is it best to keep the lid off of the pot? Why?

Yes keep the lid off during the boil! The boil drives off DMS, which results in a cooked corn aroma/flavor in your beer. If you are having trouble getting to a boil you can cover, but take the lid off when it starts to boil.

BTW you don’t need a fevorish violent boil if you can;t get to that point on a stovetop etc. I used to use a glass cooktop and could never get a strong violent boil. As long as you can get a boil, even a gentle rolling one, should be good enough.

I use my lid because of a ceramic top but keep it cracked on the back to allow the steam and the DMS to leave. I do a normal 60min boil but probably only get a real vigorous boil at the last 30min. So far no “corn” flavors or issues that I can tell and everyone that has tasted my batches likes them.

Keeping the lid off helps make the whole house smell like a brewery. What more reason do you need?
