Weird flavor from beer lines

[JONNYROTTEN]

Update: Taste came back (though not as strong) after the seltzer spent the night sitting in the line. Second pour was fine. I think I need to replace the lines eventually.

Licorice is weird flavor to pick up. Lines are cheap enough to replace...I'd open the keg and dunk a clean cup in there and see what it taste like. If it taste fine its something downstream of the keg but at least you know its not the keg...I'd disassemble the keg and clean the crap out of the dip tubes and ball/pin locks. Nows your chance to isolate the issue...Crud/ hops can get stuck in them and all fluid flows threw them

As I mentioned in the OP, already did that. Tastes great!
