Darrin's Coffee Company, Indianapolis

Standing in a smoky kitchen, with fine particles of coffee chaff drifting through the air, Darrin knew he had found his calling. It all began with a book, in which Starbucks chief Howard Schultz describes his first taste of freshly roasted coffee. For Darrin, it was as an epiphany: he had to give coffee roasting a shot. And so, standing in his kitchen with whisk in hand, he roasted the first of many batches of coffee.

Fast forward to today, and Darrin's motto is simple: to roast the best coffee possible. At Darrin's Coffee Co., he roasts a handful of different coffees as often as James Bond hires a new martini maker: weekly. Darrin then sells the resulting blends in 6- or 12-ounce bags. Brewed varieties include dark espresso, creamy lattes, and the grasshopper—a blend of green coffee, chocolate, and vanilla.
