Leftover wort from brew as starter

[Beercules1]

Just wondering if there are any rules of thumb to doing so. I saved about 1/2 a gallon of wort from my NE Brown. I put it in a jug and tossed it in the fridge. I was planning on using it as a starter. If I do so, will it be ok to use it in a lighter beer, assuming I decant the yeast after the starter has finished?

Sure! Of course, I'm assuming that you boiled it before sticking it in the fridge.

Not so good. Lacto can grow during the wort cool down, and a bit even at fridge temps. Next time, boil the wort, even briefly, before chilling and saving. I freeze mine.

If you taste it, and it's not soured, it may be salvageable if you boil it before using.

I freeze mine and then defrost and boil when I'm ready to use it.
