........That's about right. Hence the high costs of long-aged
spirits. The losses AND the storage costs have to be recovered at
final sale. User pays, as always.

........What type of pump action is it? Piston, diaphram, or
peristaltic? There are issues with each type re unwanted smells
getting into the product. Let me know the type.

........ Sounds like an interesting experiment! I don't see why it
wouldn't work, although I'd put some sort of one-way vent into the
closed system, to draw more air when necessary. The air dissolving
in the product (it will) and varying atmospheric pressure can create
a vacuum in the closed system, so more air may be needed or the
tubing will collapse, shutting down the recirculation & possibly
burning out your pump. Electricals shorting out around ethanol
fumes ain't a fun idea.
