7th batch, just boiled with lid on....

[KRASHED]

Failed to notice some critical reading on boiling with the lid off at all times.

Have been using stovetop range for first six batches and kept the lids off.

Got a highly efficient stainless steel setup with propane burner and lid. Kept the lid on as I got to boiling so damn fast I was afraid of boiling off most of my beer while I fiddled with the flow rate.

Probably opened the lid and did a slow gentle stir ever 10 minutes of the 90 minute boil for an Oktoberfest beer.

Am I screwed with DMS? Is there any way to help get rid of any excess from keeping the lid on?

Extract or all grain? What's the grain bill? With an Oktoberfest you'll be better off than if it was a lighter lager.

So you removed the lid 8 times or so... might have let off enough steam to drive off a large part of the DMS...

Nice recipe, wish I had a second fermenting chamber for lagers!

How rapidly you chilled will affect this too. Nothing to do now for this batch but wait and see.

In the meantime, fill your new kettle up with water and determine its boil off rate at the boil intensity that you want to use then adjust your recipes to the new equipment.

I agree, boil off rate is important to zero in on. It is best to control your volumes by starting with the right preboil amount and controlling it with the amount of heat, rather than the lid.
