Kolsch recipe - need help

[GoodTruble]

I must have had a bad batch of Omega Kolsch II. I brewed a 12 gallon batch and split in 2 one with raspberry one with out and both had a strange bitterness to the point they were not very enjoyable ( I could drink them but the wife would not). Since I kegged on a brew day I harvested the yeast and used it on another double batch not knowing about the bitterness issue. The next split batches had the exact same issue.

Weird. Are you sure it was 2 (II) and not 1 (I)?

Positive it was ll. Ibu on first set of split batches was 23.4 used Tettnang, second set of split batch as 13 ibu of Cluster on a pair of sours. One black berry and the other strawberry peanutbutter. You knew it was the yeast and was hoping it would fade all the way away but it remained bitter to the end. Only faded some the first week or so.
