Default How Long is Wort Fresh? (ie. Mash, Refrig, & Boil Later)

Say I mash and sparge tonight to collect my wort in my brew kettle. Can I cover the kettle, refrigerate it, and do my boil in 24/48 hours? Does the sweet wort go bad?

Man, that is tough, it is FULL of bacteria before you boil it. You would run a huge risk of souring the wort Id think, even cooled.

I do it all the time and so do a bunch of others here...you'll be fine. It won't go sour that quick and you'll be boiling it for an hour at least soon enough.

Okay, good... I understand that the boil will kill tha lacto, but they get 48 hours to live in the wort. Mashes go sour very quickly... good to hear the cooling inhibits it.

I've done it a couple of times without issue, but I've never gone more than 14 hours between collecting and starting the boil. You might try bringing the runnings up close to a boil to kill the bacteria before turning in for the night.

Yes sir. That sounds like a fine idea. But then do I have to worry about hot-side aeration on the cooling?

You'll get differing opinions on that, but I believe the consensus round here is that HSA is the bogey-man of homebrewing. I've not experienced it under this scenario, or any other for that matter.

EDIT: And The Pol beats me to it. Figures, I offer some help and I'm a day late and a dollar short.

My biggest con to the plan is the energy waste. Heating to 150, then cooling, then heating from 38 to 212.
