Copper and Aluminum

[Schlenkerla]

Dude -- I don't want to revive yet another aluminum good or bad debate, but did you read that passage you jsut quoted? The pH usually has to be above 9 for aluminum to cause metallic flavours. Not gonna happen with wort.

Also, in Palmer's latest edition (3) of his book, he very much advocates the use of aluminum.

I think you are badly misquoting him here in your post.

Feel free to quote the Beer for Dummies book, but I don't think it is regarded as highly as Palmer's book.

Flyguy - Actually, I didn't quote him all. I indicated Beer for Dummies doesn't recomend aluminum. Then pasted in Palmer's off taste paragraph under metallic. Then said try it, implying it might not be a problem.

Palmer states it can and then says it usually won't unless the pH is over 9. Not a ringing endorsement for aluminum in my opinion.

I don't have his 3rd book, why don't you post his opinion in contrast?

Since aekdbbop asked I told him what I know and warned him that it might be an issue. Nothing more.

He's got the kettle he should try it and see if it works. If I just bought one and knew I could return it for stainless model, I would do that.

Who knows maybe new kettles are heat-treated differently. I kind of doubt it myself. My Northern Brewer Catalog doesn't offer aluminum, same with Williams Brewing.

Truthfully, I don't think I gave any bad advice.

Schlenkerla -- I re-read your post, and you are right. You didn't actually say that Palmer discouraged the use of aluminum. I just read that into it. My mistake -- sorry.

No Problem! I do this everyonce in awhile myself. The problem with typing is you can't get the tone or inflection as one does in speech. Misunderstandings are therefore all too common. Its funny how you can reread something and get a new meaning.

Cheers!!
