Was using wyeast 1056. I have never had any flavor like this from this strain of yeast (US05 or California Ale by white labs). I am going to clean my lines.
I had a dry stout a few days ago that had a fresh milk note to it but it was very awesome ..i used 1084, i believe my cause was diacetyl....but with 1056 i have no clue how you got milk notes ..no matter what goes wrong with 1056 i always find it clean..wish i could have helped
did you dry hop? if so, at what temp? I ask because the last couple times I've dry hopped in the keg at racking, then straight into the fridge to carb, I've gotten a serious milky, cloudy, basically sh#t flavor for the first week or so. it's amazing how funky bad it is and then how magically it transforms after 8 or 9 days in the keg.
No dry hopping. I think maybe what I am getting is the dank/musty flavor from using too much citra hops. There is a nice citrus and slight sweetness but then that is followed by the musty/dankness.
