Suitablilty of copper for parts of brew kit

Postby Sosh » Fri Apr 15, 2005 1:04 pm

Hi,

Just wondering what the general concensus was on using copper items in the brewing process, eg brew kettle or femerter. Stainless steel is just so expensive!

Thanks

Copper is OK

Sosh: Copper is ok for plumbing use on the pre-fermentation side of things in the mash/lauter tun, boil kettle, hot liquor tank, chillers, etc. Many homebreweries are hard-plumbed with copper. It is a trace nutrient for yeast. However, once you have finished beer, I would steer away from any long-term exposure to metal (copper, brass, etc.) as it will taint the brew with a metallic flavor. So during fermentation, serving, etc. I would stay with food-grade plastics or stainless steel. Does that help?
