Killing lacto in wort bow long to boil

[anico4704]

If I wanted to leave my wort sitting for 8 hours before the boil, can I bring the temp of the wort up to a boil for a minute and cut the heat. Will that be sufficient in killing the bugs until I can fully boil in 8 hours?

If you bring the wort up to 161 Degrees F for 15 seconds it will pasteurize the wort. You will be safe from bugs at that point, but you will need to keep it covered that whole time or something else could get in to the wort once it cools down.
