beer in the line

[mfischer2]

After I finish filling my cup from my keg, there's beer that stays in the line. Is this a problem? Does air leach into that line? If its been awhile since I've drank, I usually dump the first half cup before filling again.

if you have clean lines and forward sealing taps you should be fine.

Or just drink more.

The beer in the line will be fine, but it will probably go flat. As long as you keep the post and connector clean and sanitary when you hook up the line, it will not go funky on you.

If the faucet is sticking on you, squirt a little water or starsan up there when you are done for the night.

Once the qd is attached to the keg, isn't the inside of the tubing basically an extension of the inside of the keg? I don't see why it would go flat. (Admission: I only use ~18" serving lines attached to picnic taps, so even if the beer in my lines did go flat, I would barely notice it.)

I don't know why, but it does. My lines are all at least 6' and some twice that so I get a fair slug of line-beer at first pour which makes it more obvious I guess.

Maybe the tubing is CO2 permeable even though the liquid can't get out? Hmm I wonder if O2 is getting in that way too, then. Never noticed a huge oxidation problem with the beer in the line, but I haven't been looking for it either. I might now.
