This has been alluded to a lot in pressure canning wort discussions, but I can't find any simple info on making sterile water. Most brewers that can wort mention that they also like to make up some jars of water, but no real info is given. I've read 15 PSI for 30 min. How much head space do I need to leave? If anyone can give some tips on what they do, I'd appreciate it. Thanks!

250 F for 15 minutes (15 lbs) will certainly do it.
I'd fill it almost all the way up and let it rip. Let it cool down on it's own. Letting the pressure out too quickly will drop the boiling point and it will boil half the water out of the jars.
Then place boiled lids on jars and screw them down.

I do about 1/2 to 1" of headroom on wort. Probably would do similar for water.
