Actually I did replace the o-rings, cleaned the dip tubes, star san'd it all - but I did also get a bit liberal with the keg lube as well. After that I connected it, put it on 30psi and forgot it for 5 days - wups - then disconnected left the purge valve open a couple of days, connected poured / disconnected - open it up, put in pectin enzyme - connected poured / disconnected - put in gelatin / connected poured / poured / poured - swore !@#$ - poured - swore @#$!
You get the idea - somewhere in there somehow something went wrong. Although, I do have to say that even right after the boil this batch never did smell or taste right... I still suspect there might be something in addition to infection - I'm leaning towards the orange peel...
