Tandem Coffee Roasters is a specialty coffee roaster based in Portland, Maine, with two cafes—a combined roastery on Anderson Street and a coffee-and-bakery spot on Congress Street. They source single-origin beans from producers like Fausto Romo in Ecuador and Faver Ninco in Colombia, roasting toward bright, fruit-forward profiles: creamy raspberry, sweet apple, mango, and floral florality. Subscriptions are available in single origin and blend formats, and new coffees drop regularly. Beyond the beans, there's a bakery, a vinyl collection, and a rewards program called Venkmans. Their motto says it all: 'Spread Joy.' It's specialty coffee without the pretension—thoughtful sourcing, consistent roasting, and a genuinely good vibe from a roaster that feels intentional, not corporate.
