      I have no way of analyzing them , I do know that it has been discussed on several professional levels, and the hydrocarbons vary with fermentation yeasts and type of worts.

      Henry,

      Any idea as to what kinds of carbon compounds are deposited on the copper? The chemistry of flavors is a big interest of mine.

Even the larger distilleries that have stainless stills know the benefits of commer on flavor and have removable copper plates in their stills. Yes you must clean copper more frequently but I believe it makes a cleaned distillate. I use a straight through Liebeg design that has an internal baffle that can be disassembled for cleaning with ordinary tube brushes.
