Lid on or off

[Brewberoza]

I am wondering if anyone knows whether leaving the lid on with DME or LME is as serious as doing so with grain. I am hoping to restart home brewing but dont want to alienate everyone I live with my steaming up the kitchen so work arounds are welcome.

Malt extract is made by mashing then evaporating the wort into LME. Malt extract skips out the mashing process and IMHO it still needs boiling, and therefore still needs the lid of to allow the boil off of the precursors to DMS etc.

LME (and DME) production

I like their experiments but they shouldn’t been seen as conclusive evidence, they usual a one off brew with a small sample. By all means use then as a guide/reference but don’t let them dictate your process.

Hi!
So there is room for further study - perhaps we should be trying lid on/lid off experiments ourselves - not forgetting partially covering the boil.

Lid half on for me as it's the only way to keep a good strong rolling boil with my electric hob. I've not ever suffered from any off-flavours like those described for DMS.
