Beer from keg tastes like plastic

[AlphaWolf-Brewery]

I was outta town for about a week and when I got home I poured myself a pint from my keg and it tasted like plastic. This beer tasted great before I left. Could it be the beer that sat in the hose for the week picked up the plastic taste from the hose? If so do most people just pour away the first couple oz's after not pouring a beer for a few days? Thanks

How old are the lines? I some times get a plastic taste when I change out beer lines. It always goes away after a pint or so.

Yeah the lines are brand new.

I recall someone on here comparing beer lines based on flavor and settled on the bev seal ultra 235. I use them as well and haven't had problems with flavor. Mine are 1/4" (smallest they sell) and the restriction is .4 PSI/ft. That's great for my setup but I don't know if that would be a problem for you

Yeah, just dump the first 1oz.
