In 1979, two University of Colorado professors decided to open Boulder Brewing Company–the forty-third brewery in the nation and the first in the state since Prohibition. Over the next four decades, young entrepreneurs from across the country flocked to the picturesque region to follow their bliss and brew beer. The county’s brewing heritage is brimming with stories of how a band of ragtag ruffians helped launch a nationwide revolution. The likes of Oskar Blues, Avery Brewing Company and Left Hand Brewing Company laid the fertile ground for torchbearers such as Upslope, Bootstrap Brewing and many others. Packed with firsthand accounts from adventurous brewers, Michael J. Casey recounts the tale of those who turned Boulder County into ground zero for craft beer in the Centennial State.
