Default Copper reacts with wort?

I made myself a copper wort immersion chiller which I used for the first time today. I had cleaned it with VWP sanitising solution, then rinsed thoroughly. What bothers me is that the whole coil was slightly dull when it went in (as you'd expect from unpolished metal) but when it came out of the wort, especially the base (where the cold water enters), was quite shiney. Now this suggests to me that something in the wort has stripped the oxidation off the coil but more worryingly that is presumably in my beer now.

I pitched a freshly washed Wyeast Brit Ale II into it and it's bubbling away happily after only a few hours, but I am worried that the flavour might have been effected. I realise that only time will tell on this, but does anyone know of this situation? Is it something of nothing?

Thanks.

The wort is acid-washing the copper. Completely normal.

Thanks guys. I was rather concerned earlier when I saw what was happening! I did'nt have any other way to cool down 4.5 gallons of wort so I just pushed through with hope!

Cheers.

Actually this ís bad for you. Copper is not good for you and it doesn't leave your body very very quickly at all once ingested. I don't understand why people here aren't worried by this.

Once your retinas turn blue, your hair turns spiky and you go nuckin' futs you'll regret it.

Make those damn things out of either just Iron or stainless steel, chromium and nickel aren't exceedingly healthy either but better than copper...

Does anyone have anything to add to Nerro's comments? I thought copper immersion chillers were sold by homebrew shops . . . . such things would surely need to be safe in order be on sale?

When did you do the brasso addition? If done too early it can lead to excessive polishing of the wort chiller.

When you would need to be worried is if the copper is turning green and blue. if it was just darker I wouldn't worry for one moment. As mentioned in a book I am reading, people and breweries have been using copper for several hundred years.

It was just darker and dull, just like any lump of copper that is left about.

Sure, I'll add something to Nerro's comments. He's full of crap. Copper is indeed good for you, and it's a necessary element of life. Copper is important for the formation of bone, hemoglobin and red blood cells. Copper also helps keeps nerves healthy, and is involved in hair and skin coloring and sensitivity to taste as well as aiding in the healing process.

My stepmother has a rare disease that doesn't let her body process out copper and other elements. She can't drink anything other than distilled water, because of mineral content. It's caused her joints to stiffen to the point it's hard for her to walk and talk, but she neither has blue retinas, spiky hair, or is crazy. The only time to worry about copper is when it gets green and and blue like the Statue of Liberty. The patina is toxic, but easily polishes off.
