Good point, and I plan to use steam pipe insulation on the column, but couldn't resist taking a purdy picture first.
I'm planning to use an existing glass Alhin condenser for refluxing and another existing Liebig for the product condenser, so the additional prototype costs are minimal. It would be easy however, to wrap copper reflux and product condensers.
With one meter of column below the refluxing condenser, I'm hoping that it will fractionate closely enough to redistill low octane drinking alcohol into 190 proof in a single pass.
Since I'm not planning to run mash or wash, I'm not planning to add any copper scrubbers in the mix to react with the sulphides, and so keeping the stainless clean, should be relatively easy.
PS: For ya'll in the parts of the world where it is legal, a meter of reflux column should also allow ya'll to distill off fermented mashes, beers, and washes, as well as wines, and you probably want to mix in a few copper pot scrubbers.
A meter of column should also be tall enough to easily fractionate off the methanol and ethyl acetate fore shots produced in those processes, as well as the heads and tails.
