Book excerpt: From the mash in pioneer stills to the Malört in a hipster's shot glass , David Witter explores how liquor has influenced nearly two centuries of Chicago's existence. Follow the trickle of alcohol through Chicago's history, starting with the town's first three permanent businesses: The Wolf, Green Tree and Eagle Exchange Taverns. Stir together stories from the Peoria Whiskey Trust and the Temperance Movement. The cocktails that lubricated the Levee District may have set up Chicago's first gangsters, but Prohibition-era bootleggers would change the city's identity forever. Post-Prohibition alcohol helped to create vast fortunes for Chicago based families and corporations, and the new Millennium saw KOVAL usher in a new era small and craft distilleries throughout Chicagoland. Sample a spirited history of the Windy City.
