I have a few old kegs and keg couplers. Some of the couplers don't have the stainless rod with elbows and shutoffs. 1/2" copper pipe is the same size, so I could use copper and be able to get the fittings I need, very easily.

Is there any reason copper shouldn't be used with finished beer?

Thanks

I don't know the exact reason but I have read a few times that copper before the boil is good and copper after the boil is bad.

I think there is an issue with copper in long term contact with the beer. Such as in a copper fermenter or copper fittings in a keg. The immersion chiller is not in contact long enough to be a concern.

But I don't know enough to tell you exactly why. Sorry

I wonder what is considered long term contact.

I read that that harmful materials in the copper can leach into the beer, I don't remember where I read that however.
