So I am a new cider maker, and do not ferment beer at all. I have been exploring cheap fermentation chambers to expand my product to the 20 gallon per batch step. I have looked at plastic conical inductor tanks and it made me remember, I have a tank similar in shape and near the size I am looking for. the big difference between my tank and the conical inductors is mine is copper.
So the ultimate question, can I use copper as a fermentation chamber for cider?
Here are some pictures of the tank I am thinking of using. the total volume of the the tank is 27 gallons. It needs some serious cleaning but is structurally sound. The original use for the tank was a hot water heater, circa 1900s.
So I am open to thoughts. Anyone?
