Since beginning all grain batches I have making use of that leftover grain and bottling the extra runnings from my mashtun for later use in starters. I hate having bags of DME open and half used as they always make a mess. I have also had better success with starters using wort from all grain diluted to OG 1.04 compared to 2 cups water ½ cup dme.
My question is about preserving the wort after you have bottled and procedure for making a starter:
If you take it out of the MLT boil it, and pour into sanitized bottles, then cap it, does in need to be refrigerated? What is the shelf life of this stuff? Are there any benefits to keeping it cool?
My homebrew buddies and I were discussing whether it would be safe to just open a bottle at room temp and pitch the yeast directly in, or if you would want to re-boil the wort before pitching into a starter. I lean more towards the safe side so I would always boil again before making the starter, but I wanted to see if anyone else had experience with this.
