Default wort started to ferment without yeast

so this is a sad story. i made a wonderful brew, porter-like beer, made the wort, cooled it, aerated it and put in the fermenter. Now, I left it in there for 3 days without pitching yeast. the reason was i ran out of yeast without taking notice. so i got my yeast today and wanted to pitch it in, BUT i heard the airlock bubbling!! so i opened up the fermenter and a really foul smell came out and bubbles on the top.. what the heck just happened??? i sanitised everything! snif snif snif ...

Bubbles in the airlock don't really mean it's fermenting. But if it smells really bad, chances are something bad got to it

3 days is a long time for wort to be sitting, no matter how sanitary you were....

Yeah, but you tempted fate by leaving it for three days. Sanitation may buy you some time, but you should never count on it, if you can help it.

how did you aerate it?

unless you sterilized everything (which is practically imposable) there are still a few bacteria and what not on every surface. thats why cleaning products only claim to kill 99.9% of germs. 3 days is plenty of time for the survivors to party and start eating your brew.

you can try boiling it again to kill anything that is currently living it it. but the damage is already done. there is no telling what kind of byproducts the wild what ever put into the beer. you may end up with undrinkable crap.
