Are there any metallurgists here who also brew their own beer? If so, I'd like to invite them to combine their interests and join in a planned discussion of whether it is best to use copper tubing coils or stainless steel tubing coils inside of a stainless steel beer fermenter, the coils being used as a chiller? There has been a discussion in another brewing forum about competing concerns between the two, i.e., copper conducts heat better and is easier to bend, versus copper will slowly dissolve in the acidic environment of beer. It has been suggested that this will eventually coat the stainless, sort of like 'passive' electroplating.
Naturally, I don't expect non-brewers to be too interested, but any who are already into brewing might not mind helping shed some light on this.
Anyone interested can contact me directly: snipped-for-privacy@alltel.net or join our new group:
Thanks, and please forgive this off-topic interruption.
