I have heard mention of late addition of extracts. I was under the impression that you need to boil the extract to kill off any possible nasties?
When I brew, so far always from a prepackaged kit, after the steep, I get the boil going, add the steep/rinse water, bring back to boil, add liquid extract, bring back to boil, add hops, boil 60 min, add finishing hops...
what would I gain or lose by waiting to add the extract? and how late into the boil is considered a late extract addition?
Thanks and Cheers!
