several of my neighbors make wine, and then grappa from the leftover mash. it is also readily available in liquor stores, both plain and with fruit (pears, lemons, plums, etc) swimming in it.
my macedonian neighbor makes some mean grappa. the first year he lived next to me, i was fascinated watching him make wine.
a few weeks later, as i was working in my garden one sunday morning, i saw him hauling sheets of copper, tubing, buckets, and a giant fish tank into his garage.
several hours later, he stumbled out of his garage with a small jug, offering me a swig of some clear "viskey" as he called it. nasty stuff. it burned the whole way down. each time...
so i jumped over the fence and went into his garage to take a look at what he built. it was a big, phallic still with a turkey fryer burner underneath, a coil of tubing going through a fishtank full of icewater, and the final product dripping into a bucket with a hydrometer clipped to the side.
at the time, i wasn't sure if making distilled spirits was legal in the u.s., so i told him to close the doors of his garage in case the police drive by. he said in his heavy accent and gesturing with his hands, "no close doors. BOOM!"
fortunately, he had enough air flow with the doors open to prevent "boom", lol.
