Moonshiners.

Home distillation of liquor used to be the province of backwoods bootleggers. Up until 1974, when the world price of sugar skyrocketed, commercial moonshiners throughout the Southeastern United States made enough money making hooch that it was worth the risk of getting caught by federal revenuers.

Today, making your own liquor is as illegal as ever, and a lot less lucrative. In fact, it's considerably cheaper to buy it off the shelf.

As a result, today's home distillers are quintessential do-it-yourselfers. Many are engineers and techies, much like the liquor connoisseurs who attend the Whiskies of the World Expo each year in San Francisco. "We have a whole audience that we refer to as the whiskey geek," event founder and organizer Riannon Walsh says. "I think 90 percent of them are techies."
