Shortwave Coffee, a family-run roastery founded in Missouri in 2014, accepts bitcoin at its registers across five locations in three states. The company operates two shops in Columbia, one in St. Louis, another in Minneapolis and a roastery in Tampa. The St. Louis location is at 33 N. Sarah Street in the Central West End and includes an outdoor patio, a wildflower garden, indoor seating for more than 75 people and ample street parking. Local bitcoiners contacted baristas and repeatedly emailed the company before receiving confirmation in July 2026. The story also highlights Square's March 2026 move to automatically enable bitcoin acceptance for up to 4 million terminals, although the rollout has been gradual. Bitcoin Magazine's Vagabond presents Shortwave as part of a wider effort to identify independent businesses that accept bitcoin and invites readers to submit similar examples to Vagabond@b.tc.
