Moonshine

Moonshine was a clear, bootlegged alcohol distilled using a still.

Also known as white lightning, it was 198 proof, a nearly pure ethanol. 

History
In 2253, Bob Brien and Montgomery Scott distilled moonshine from a still hidden in engineering aboard the USS Enterprise (NCC-1701). Unknowingly, however, the pipes had been been exposed to gamma rays, which made the resulting ethanol particularly intoxicating. Luckily, the effects were not permanently damaging. 

In April 2063, the Crash & Burn bar smelled of moonshine, a smell that gave Lily Sloane a headache. Zefram Cochrane drank ten shots of it. He also christened Phoenix with a bottle of it. 

In 2270, James T. Kirk brought Leonard McCoy a decanter of moonshine as a peace offering. One shot of it numbed all pain. Officially the captain was unaware that a still in engineering produced the illegal beverage, but he was able to get some from former security chief O'Shay. 

In 2270 while a Tomariian prisoner, Scott distilled a strong moonshine from a dandelion-like plant. He often shared it with IIob, his captor. 

In 2270 during a visit to Yonada, Keridwen Llewellyn poured McCoy a drink of moonshine. 

Lumberjacks still made moonshine in Alaska in the 24th century. 

In 2350, Sisko used to drink moonshine whiskey with his father in Louisiana. He recalled that it went down roughly, burning the throat on its way to his stomach. 

While competing in a pan-dimensional contest, Tom Paris kept his focus by reminding himself he was not a jockey competing for moonshine or holoprograms.
