Just got half way through brewing a batch of mild, got the wort up to a boil and before i could add my hops the boiler sprang a leak. i quickly poured the hot wort into a sanitised fermentor and sealed it. I can now add some sealent to my boiler and finish the brew later. The question is how long have i got until it starts going off. Will it sour up with no hops in there? I want to try and do it tomorrow but might not have time. Can I leave it till sunday?
