What is this brown stuff inside my tail pieces?

Post by Rezzin »

It's been over a year or longer (maybe 2? :oops: ) since I've cleaned out and changed the liquid tubing and hardware in my kegerator. I took everything apart and have it all soaking in a PBW bath but I noticed this brown buildup in each of the tail pieces that attach to the shanks... inside the barbed fitting and underneath the black rubber ring that sits between the tail piece and shank.

Is this beer stone? Rust?

Everything is still soaking right now so hopefully it comes off nicely but I was pretty surprised I saw that. I'm hoping it's just caked on yeast or something.

I've decided to start with a Common this weekend to take advantage of the cold weather.

Beerstone's my guess. If you need some BLC (beer line cleaner) I've got some. You may need to take a bristle brush to them as well to get the gunk off.

Good luck on the common! Do you need my recipe?????? (I posted this dec 13 2005 on the BCJP forum)

Here's a recipe I'd made in Feb. '05 when it was cool here in So. Cal., then "lagered" it in my 32 F. beer fridge and kinda forgot about it till November 05.
I entered it in the MASH and HHHBC and took 1st place with a 43 and 38 respectivly.

It's a realllly nice beer.
Hope some of you can use this info.

What's left is a gallon in the keg, the great hop nose is still there backed by malt but the bitterness is a bit light. Next time I'll increase the NB and not use the cascade/centennial as dryhop.
Otherwise this is a KILLER beer and has been loved by all whenever I've served it.

It's probably yeast, mold, sediment and trub. It collects pretty quickly which is why you shouldn't wait two years :!:

haha yeah I know. :( Well I'm happy to report that most of the crud came off but it seemed to have 'stained' whatever it touched. After a soak in PBW, BLC, and Starsan, I hooked everything back up. It's nice having clean beer lines!

Looks like rain is in the forecast for the next several days so hopefully my first brew session in 1/2 a year will be next week sometime. I'll be in TX the majority of the week afterwards so I'd at least like to be around for the first several days during primary.

Hey rezzin,

I was reading a post about a gut who was switching to kegs and you showed some great pictures of a freezer kegerator that you made from a freezer you got from home depot. I am very interested in making this same set up. Would you be willing to take one more picture from the back and post it. I am not sure how your were able to move the lid up without moving the brackets up on the wood frame, which I am assuming you did. If this was done, what did you do with the holes in the freezer from wherethe brackets originally were.

Sorry to crash your question about his beer lines, but I did not see a way to email you or contact you any other way. hope you dont mind. any sugestions on the kegerator would be helpful. Thanks.

Sure thing - its kinda late and really cold in the garage so I'll do it wheni get home from work tomorrow. Once you see the pics you'll see how easy it is. You just remove the hinges from bottom part of the freezer and attack it to the collar.

you can email me at rezzin at socal dot rr dot com if you need to 'pm' me.
