Old thread i know, but my outcome is:-
My sanitation was not up to scratch, and it did not show through untill substansial lag times created by low temp fermentation.
I had the following:-
Crud under lid oring (normally clean every 2nd or third batch) practise now rectified.
Crud behind tap seal. Same procedure. Now clean each time.
How do i know this, same enviornment, same routine. Just tried the 4th batch after tipping 3 batches from the same fermentor & it is nice beer.
I also noted a complete clean on the sheet i put with the batch in the cupboard.
Sorry i wasted so much of your time guys.
