Freeze leftover wort?

[TimG]

So I usually have a couple liters of leftover wort after a brew. Can I freeze this in a few jars for future starters? No need to be real sterile or anything as it will be boiled again correct?

got a pressure cooker? Put them in Mason jars and process them in it for a half hour. I pressure can all of my extra wort. It is as good as sterile in the jar, no thawing.
Just clean and sanitize the mouth before opening and pitch into a starter.

Nope.. don't have one, but that sounds much easier than freezing/boiling. Someday..

If you do eventually go down the pressure canning route, the only thing to keep in mind beyond what Nick said, is it's a good idea to dilute it to 1.030-1.040. High gravity starter wort is not great for yeast health.
Also Tim, if you wanted to, once you've got a bit of frozen wort you could always bring it by my place to can it. Not sure if you'd really save yourself that much time in the long run, but if you needed to make a starter in a hurry one night, having those ready to go jars is super handy.
