The best liquor I ever had was by a state police detective who had been home distilling since he was 12. It was made from rye and corn, but tasted like peaches.
I think it is kind of magical to witness the process. I only experimented a few times, and never aged it, so every was very sharp. The best was a sharp brandy made from a bottle of wine I bought. The worst was using a leftover keg of beer, which bittered the copper pipe, so everything after tasted like gin.
I would recommend people try it. You can make one out of copper pipe from a hardware store, a few fittings and a pressure cooker. Be safe, of course, and remember that ethanol is used as a preventative for methanol poisoning :)
To me, the refractive index of hot ethanol makes it sparkle like a diamond when leaving the still.
I don't drink anymore, but man I loved distilling. It's like magic.
The best I’ve ever done was a double distilled Spanish box wine we picked up for 1eur/l. The wine was undrinkable, but the brandy was sooooo smooth.
Next best was cheap tokaij furmint, distilled once and then mixed back into some of the undistilled wine. Basically the same thing as pineau de charante, but Hungarian and on the kitchen table.
