    Oh of course, the immersion chiller.

    I googled "zinc in coins" before my previous post and yes, the do have very little copper but have a lot of zinc. Luckily though, all of the copper is in the plating which putis it conviently on the outside for max exposure : )

    Wewe you unsure of whether pennies had zinc in them, or whether it would end up in the beer from simple exposure?

    I was unsure if you could get enough zinc simply by immersing it in large format solid form. Maybe you can. I just don't know.

    I use a half of a 15 mg. zinc diet tablet to get to the correct ppm range for a 10 gallon batch.

    Thought I'd share the information Briess gave me:

    Our water contains approximately 63mg/L Sulfate and 28mg/L Chloride. We brew at 16 Plato, then concentrate to 80% or 98% solids. If Briess extracts contributes 16P to your wort you should have about 63 & 28mg/L, if 8P then 31.5 & 14mg/L.

    The only other information I can give you about our mineral profile is that our water is moderately hard.
