In the interest of saving money, what other metals besides stainless steel might be acceptable to make a grist case out of? This grist case would be suspended above the mash tun, so it would see some steam and heat. I have read that galvanized metal is food-safe, as long as the food is not acidic. I guess brewing water (and therefore steam?) is slightly acidic, but would this affect the grist case? Also, what about other possibilities like painted mild steel?

Galvanized Grist Case?

Condensate water is acidic enough to eat concrete, and will undoubtably dissolve heavy metals (cadmium, etc) from the galvanizing, which might then drip into your mash tun. SS is expensive, but find somewhere else to cut corners (your pay?) or risk exposing your customers to heavy metal poisoning.
Well-painted mild steel might work for you, but will require periodic re-painting. The best paint I've found for the brewhouse is Alloy Bond Supercoat 316L. it makes mild steel look like 316L SS, and lasts very well if used according to the instructions. I think we get it from Nether Ind.Last edited by TGTimm; 07-08-2014, 09:29 AM.Timm Turrentine
