It's called distilling, and nah I've never tried that. Believe it or not that's actually illegal in the US and quite difficult to do. Brewing beer is easy (well, brewing beer that tastes good is not so easy). Freshly distilled whiskey is clear and almost all alcohol. It's actually only called moonshine if it's made from corn mash. Commercial distillers age the fresh whiskey in charred oak barrels for the period of time. Jack Daniels for example ages their black label for seven years. During that time it picks up it's color and flavor interacting with the barrel wood and as the ingredients in the wort begin to chemically seperate and the alcohol breaks down. Then they dilute it to reach the percentage they want becasue fresh out of the barrel it's around 120 proof. There was a great show on Discovery about that a few years back.
Do you work in a brewery or something? Because that was fascinating to read.
