kamsynth Posted May 22, 2019 Share Posted May 22, 2019 We have a 200L ss tank holding our vodka, with Summer coming it's starting to get pretty hot in the distillery. I bought a copper coil immersion chiller for cooling down the vodka but now I am wondering if copper will leach into the vodka if the chiller stays in the tank. Does anyone know anything about this, or copper reactivity/toxicity? I need to get the vodka reasonably cool for bottling. Link to comment Share on other sites More sharing options...
Southernhighlander Posted May 23, 2019 Share Posted May 23, 2019 Is your copper coil corroding and turning green? Link to comment Share on other sites More sharing options...
glisade Posted May 23, 2019 Share Posted May 23, 2019 You could get a SS coil, something like this: http://www.bubbasbarrels.com/cooling-coil Not as cheap as a copper coil from Home Depot but easier to deal with if you're worried about copper flavor in your vodka.

kamsynth Posted May 23, 2019 Author Share Posted May 23, 2019 1.There's no corrosion or oxidation, the copper is shiny and new. 2. Our mash is cooled with a water jacket. 3. I'll probably upgrade to SS soon, the copper coil was the largest option that was available (plus it was a good price) There's nothing to indicate that anything is going wrong here, I'm a guy who started a distillery with no prior distilling experience, so I feel I need to be extra cautious. I've consulted some chemists/chemistry nerds and no one seems to think that this is going to be an issue, so I guess it's all clear from here. Better safe than sorry!

I think that you are probably okay with the copper coil. I have stainless cooling coils sized specifically for what you need for $250.00 Carl's design (Bubbas Barrels) is not the correct configuration for what you want to do, while mine is. Carl is a great guy and friend of mine and he would probably tell you the same. Link to comment Share on other sites More sharing options...
