Filtering near-pure alcohol - suggestions?
Posted: Mon Aug 19, 2013 10:14 am
Hi all...
I'm not a distiller, but am making some home liqueurs from 95% alcohol (Everclear) and herbs/spices.
I have a need to filter my concoctions to remove fine particles, and have been looking around; I saw various wine and beer targeted filtering systems, and ended up getting this one:

However, I was wary of the plastic it was made from, so I tested it by dumping a cup of alcohol into the main container and letting it sit for a couple of days.
After evaporating the alcohol, I found some plastic residue left over - so it had been dissolved. I contacted the distributor (The Vintage Shop), and they said they didn't recommend it for this use (which I don't think is mentioned on any website).
I also contacted the maker of the Buon Vino motorized filtering machines, and they told me they also couldn't guarantee pure alcohol wouldn't damage the plastic/rubber parts inside it (valves mostly), nor that sparks from the engine might not set the alcohol on fire.
Can anyone recommend a good way of filtering out particulate around 20-50 microns from pure alcohol in a way that won't dissolve anything?
