I took a growler of this to band night last night and somethings going wrong with it. I thought it was just me being critical of my beer but all agreed that while not bad as in an infection, it's changed. One person said it was almost a semi-metallic taste. Maybe all the hops from the Farmhouse Blend are now starting to fight for flavor control.

So, I'm going to keg hop with about an ounce of Amarillo or Cascade and see what happens in 2 days. I don't think there's more than half a keg left so I'll see what this does as a mask for the possible off flavor.
Only other thing to check is the growler though the last glass pour directly from the keg was starting to make me question the taste as well. I am pretty sure what is not the problem and that's the lines. I clean the lines with EVERY keg I change, flushing them and cleaning the tap as well as the ball lock fittings. No way is there funk there.
As I said, still drinkable, just not the greatest, freshest taste that it gave me until about a week ago.
