Beer Line Brown Near Faucet

[yo1dog]

My keg of home-brewed coffee malt stout was almost empty so I untapped the keg, leaving beer in the line. Two days latter I drain and take out the beer line for cleaning and notice that the beer line is brown at the end that connects to the faucet shank in my tower (I have a keezer) and fades to the normal, clear color over the length of about 1'. I ran BLC through the lines for about 15 mins and let it sit in the lines for about 15 mins. The brown got lighter but is still there. I never turned off the keezer; It was always on, keeping everything cold.

I also had a keg of home-brewed IPA in the same keezer that was emptied earlier and cleaned at the same time. There are no problems with the beer lines for the IPA, however. The IPA was completely emptied so there was no beer left in the lines for that keg. The IPA was drank more often than the stout, but we still poured a beer of the stout at least once every 3 days.

I didn't have a blower in my keezer for the life of these kegs; Maybe the warmth in the tower got to the stout?


What caused the brown stains in my beer line? How can I get rid it? Do I need to? Can I still use it? I will post a picture when I get home. Thanks!

Beer line is pretty cheap. I would replace it and not worry about it. If you would rather clean it, I would run BLC through it and let it sit for a few hours/days. See if that helps.

I'm going to assume that's just a simple stubborn deposit, but if this was a barrier line perhaps the barb damaged the lining and the stout found its way in between the liner and the tubing body...

Cheers!
