Bonnie Sigwalt's life changed the moment she tasted her first Cadbury Creme Egg. She was only four years old, but the sweet treat made a lasting impression. Today, Bonnie—sometimes known as "Coco"—has turned her passion for chocolate into a profession, serving as the chief Chocolate Taster for DC Metro Chocolate Tours. She is joined in her confectionary calling by fellow expert tour guides and chocolatiers who all have shared interests—namely, a love of chocolate and an extensive knowledge of DC history.

The cocoa experts lead groups on walking adventures of historic Capital neighborhoods, from the centuries-old homes of Georgetown to the artistically inspiring environs of U-Street. But the focus naturally remains on the chocolate—each excursion stops at local bakeries, candy shops, or even a cosmetics company that sells cocoa-infused skincare products. The sweets also serve as inspiration for chocolate-making workshops or tasting sessions. During the latter, groups eschew walking for a different kind of journey. They follow the history of the cacao bean, from its origins in the mountains of Peru to its current status as "World's Favorite Plant."
