 I have been thinking about this for a while. If I wanted to brew, say 10 gallons instead of 5, split the wort into two 5 gallon batches and use different hops and stuff, how long can wort be kept in like a 5 gallong carboy sealed and either at room temp or maybe somewhat colder in my kegerator? I am thinking maybe just a day or two as I only have one propane burner to use and one of my boil kettles is a cut down keg, so 5 gallons there would probably barely fill the bottom. LOL. Anyway, like I said, I was just thinking if I use the same grain bill I can make a 10 gallon batch and split it as long as the wort will be ok for a day or two in some sort of vessel of storage. Thoughts?

My experience is a day or 2 at cold temps, sealed, is OK as long as you boil it after storage. But you're playing with possible botulism, so I won't recommend doing it.

Got it.  Thank you for the info.  Don't want to get anybody or myself sick while drinking.  Hungover is another thing altogether.  LOL.

I used to keep the brew overnight and pitch in the morning. I did this to use wort from the brewday to make a starter with and would pitch the following morning. It was 15 gallon batches and I was trying to save on yeast cost. I don’t do that anymore after discovering all the great dry yeast options but I don’t recall ever having a problem. I would seal the fermenter and pressurize with co2.
