I understand that getting the last one percent or so of the water, etc.,
out of the ethanol is a fairly complex process. That alone, might make a
home-sized project non-productive.

I doubt that the alcohol has to have the last 1% water out since they use
alcohol to remove water from gas tanks (Heet). From what I've read, size 3A
zeolite molecular sieve will absorb water but not alcohol. And you can dry
and reuse the zeolite.

I like your take on the plc approach, though. I am new to Arduino as a
microprocessor, and I can see that a lot of folks use them for automating
beer production.

I have 3 Arduino boards, they would be a good controller for such a project.
The handy thing about the PLC is I have modules for I/O for discrete and
analog + temperature sensing & load cells, also have a couple of touch
screen HMI panels. After finding out what works for controls on the PLC, it
would be nice to convert to an Arduino, my industrial PLC's are rather
bulky, my control cabinet might be bigger than the still.
